Changing navigation bar color in Swift

Navigation Bar:

navigationController?.navigationBar.barTintColor = UIColor.green

Replace greenColor with whatever UIColor you want, you can use an RGB too if you prefer.

Navigation Bar Text:

navigationController?.navigationBar.titleTextAttributes = [.foregroundColor: UIColor.orange]

Replace orangeColor with whatever color you like.

Tab Bar:

tabBarController?.tabBar.barTintColor = UIColor.brown

Tab Bar Text:

tabBarController?.tabBar.tintColor = UIColor.yellow

On the last two, replace brownColor and yellowColor with the color of your choice.

Here are some very basic appearance customization that you can apply app wide:

UINavigationBar.appearance().backgroundColor = UIColor.greenColor()
UIBarButtonItem.appearance().tintColor = UIColor.magentaColor()
//Since iOS 7.0 UITextAttributeTextColor was replaced by NSForegroundColorAttributeName
UINavigationBar.appearance().titleTextAttributes = [UITextAttributeTextColor: UIColor.blueColor()]
UITabBar.appearance().backgroundColor = UIColor.yellowColor();

Swift 5.4.2:

UINavigationBar.appearance().backgroundColor = .green // backgorund color with gradient
// or
UINavigationBar.appearance().barTintColor = .green  // solid color
    
UIBarButtonItem.appearance().tintColor = .magenta
UINavigationBar.appearance().titleTextAttributes = [NSAttributedString.Key.foregroundColor : UIColor.blue]
UITabBar.appearance().barTintColor = .yellow

More about UIAppearance API in Swift you can read here.

Updated for Swift 3, 4, 4.2, 5+

// setup navBar.....
UINavigationBar.appearance().barTintColor = .black
UINavigationBar.appearance().tintColor = .white
UINavigationBar.appearance().titleTextAttributes = [NSForegroundColorAttributeName: UIColor.white]
UINavigationBar.appearance().isTranslucent = false

Swift 4

UINavigationBar.appearance().barTintColor = .black
UINavigationBar.appearance().tintColor = .white
UINavigationBar.appearance().titleTextAttributes = [NSAttributedStringKey.foregroundColor: UIColor.white]
UINavigationBar.appearance().isTranslucent = false

Swift 4.2, 5+

UINavigationBar.appearance().barTintColor = .black
UINavigationBar.appearance().tintColor = .white
UINavigationBar.appearance().titleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.white]
UINavigationBar.appearance().isTranslucent = false

if you want to work with large title, add this line:

UINavigationBar.navigationBar.prefersLargeTitles = true

Also can check here : https://github.com/hasnine/iOSUtilitiesSource

UINavigationBar.appearance().barTintColor = UIColor(red: 46.0/255.0, green: 14.0/255.0, blue: 74.0/255.0, alpha: 1.0)
UINavigationBar.appearance().tintColor = UIColor.whiteColor()
UINavigationBar.appearance().titleTextAttributes = [NSForegroundColorAttributeName : UIColor.whiteColor()]

Just paste this line in didFinishLaunchingWithOptions in your code.

Within AppDelegate, this has globally changed the format of the NavBar and removes the bottom line/border (which is a problem area for most people) to give you what I think you and others are looking for:

 func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

    UINavigationBar.appearance().setBackgroundImage(UIImage(), forBarPosition: UIBarPosition.Any, barMetrics: UIBarMetrics.Default)
    UINavigationBar.appearance().shadowImage = UIImage()
    UINavigationBar.appearance().tintColor = UIColor.whiteColor()
    UINavigationBar.appearance().barTintColor = Style.SELECTED_COLOR
    UINavigationBar.appearance().translucent = false
    UINavigationBar.appearance().clipsToBounds = false
    UINavigationBar.appearance().backgroundColor = Style.SELECTED_COLOR
    UINavigationBar.appearance().titleTextAttributes = [NSFontAttributeName : (UIFont(name: "FONT NAME", size: 18))!, NSForegroundColorAttributeName: UIColor.whiteColor()] }

Then you can setup a Constants.swift file, and contained is a Style struct with colors and fonts etc. You can then add a tableView/pickerView to any ViewController and use "availableThemes" array to allow user to change themeColor.

The beautiful thing about this is you can use one reference throughout your whole app for each colour and it'll update based on the user's selected "Theme" and without one it defaults to theme1():

import Foundation
import UIKit

struct Style {


static let availableThemes = ["Theme 1","Theme 2","Theme 3"]

static func loadTheme(){
    let defaults = NSUserDefaults.standardUserDefaults()
    if let name = defaults.stringForKey("Theme"){
        // Select the Theme
        if name == availableThemes[0]   { theme1()  }
        if name == availableThemes[1]   { theme2()  }
        if name == availableThemes[2]   { theme3()  }
    }else{
        defaults.setObject(availableThemes[0], forKey: "Theme")
        theme1()
    }
}

 // Colors specific to theme - can include multiple colours here for each one
static func theme1(){
   static var SELECTED_COLOR = UIColor(red:70/255, green: 38/255, blue: 92/255, alpha: 1) }

static func theme2(){
    static var SELECTED_COLOR = UIColor(red:255/255, green: 255/255, blue: 255/255, alpha: 1) }

static func theme3(){
    static var SELECTED_COLOR = UIColor(red:90/255, green: 50/255, blue: 120/255, alpha: 1) } ...

To do this on storyboard (Interface Builder Inspector)

With help of IBDesignable, we can add more options to Interface Builder Inspector for UINavigationController and tweak them on storyboard. First, add the following code to your project.

@IBDesignable extension UINavigationController {
    @IBInspectable var barTintColor: UIColor? {
        set {
            guard let uiColor = newValue else { return }
            navigationBar.barTintColor = uiColor
        }
        get {
            guard let color = navigationBar.barTintColor else { return nil }
            return color
        }
    }
}

Then simply set the attributes for navigation controller on storyboard.

This approach may also be used to manage the color of the navigation bar text from the storyboard:

@IBInspectable var barTextColor: UIColor? {
  set {
    guard let uiColor = newValue else {return}
    navigationBar.titleTextAttributes = [NSAttributedStringKey.foregroundColor: uiColor]
  }
  get {
    guard let textAttributes = navigationBar.titleTextAttributes else { return nil }
    return textAttributes[NSAttributedStringKey.foregroundColor] as? UIColor
  }
}

Swift 4:

Perfectly working code to change the navigation bar appearance at application level.

https://i.stack.imgur.com/rSnvn.png

// MARK: Navigation Bar Customisation

// To change background colour.
UINavigationBar.appearance().barTintColor = .init(red: 23.0/255, green: 197.0/255, blue: 157.0/255, alpha: 1.0)

// To change colour of tappable items.
UINavigationBar.appearance().tintColor = .white

// To apply textAttributes to title i.e. colour, font etc.
UINavigationBar.appearance().titleTextAttributes = [.foregroundColor : UIColor.white,
                                                    .font : UIFont.init(name: "AvenirNext-DemiBold", size: 22.0)!]
// To control navigation bar's translucency.
UINavigationBar.appearance().isTranslucent = false

Happy Coding!

UINavigationBar.appearance().barTintColor

worked for me

SWIFT 4 - Smooth transition (best solution):

If you're moving back from a navigation controller and you have to set a diffrent color on the navigation controller you pushed from you want to use

override func willMove(toParentViewController parent: UIViewController?) {
    navigationController?.navigationBar.barTintColor = .white
    navigationController?.navigationBar.tintColor = Constants.AppColor
}

instead of putting it in the viewWillAppear so the transition is cleaner.

SWIFT 4.2

override func willMove(toParent parent: UIViewController?) {
    navigationController?.navigationBar.barTintColor = UIColor.black
    navigationController?.navigationBar.tintColor = UIColor.black
}

Below Codes are working for iOS 15

if #available(iOS 15, *) {
        // Navigation Bar background color
        let appearance = UINavigationBarAppearance()
        appearance.configureWithOpaqueBackground()
        appearance.backgroundColor = UIColor.yourColor
        
        // setup title font color
        let titleAttribute = [NSAttributedString.Key.font: UIFont.systemFont(ofSize: 25, weight: .bold), NSAttributedString.Key.foregroundColor: UIColor.yourColor]
        appearance.titleTextAttributes = titleAttribute
        
        navigationController?.navigationBar.standardAppearance = appearance
        navigationController?.navigationBar.scrollEdgeAppearance = appearance
    }

In Swift 4

You can change the color of navigation bar. Just use this below code snippet in viewDidLoad()

Navigation Bar color

self.navigationController?.navigationBar.barTintColor = UIColor.white

Navigation Bar Text Color

self.navigationController?.navigationBar.titleTextAttributes = [NSAttributedStringKey.foregroundColor: UIColor.purple]

For iOS 11 Large Title Navigation Bar, you need to use largeTitleTextAttributes property

self.navigationController?.navigationBar.largeTitleTextAttributes = [NSAttributedStringKey.foregroundColor: UIColor.purple]

The appearance() function not always work for me. So I prefer to create a NC object and change its attributes.

var navBarColor = navigationController!.navigationBar
navBarColor.barTintColor =
    UIColor(red:  255/255.0, green: 0/255.0, blue: 0/255.0, alpha: 100.0/100.0)
navBarColor.titleTextAttributes =
    [NSForegroundColorAttributeName: UIColor.whiteColor()]

Also if you want to add an image instead of just text, that works as well

var imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 70, height: 70))
imageView.contentMode = .ScaleAspectFit

var image = UIImage(named: "logo")
imageView.image = image
navigationItem.titleView = imageView

Swift 5, an easy approach with UINavigationController extension. At the bottom of this answer are extensions and previews.

First view controller (Home):

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)

    navigationController?.setTintColor(.white)
    navigationController?.backgroundColor(.orange)
}

Second view controller (Details):

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    navigationController?.transparentNavigationBar()
    navigationController?.setTintColor(.black)
}

Extensions for UINavigationController:

extension UINavigationController {
    func transparentNavigationBar() {
        self.navigationBar.setBackgroundImage(UIImage(), for: .default)
        self.navigationBar.shadowImage = UIImage()
        self.navigationBar.isTranslucent = true
    }

    func setTintColor(_ color: UIColor) {
        self.navigationBar.titleTextAttributes = [NSAttributedString.Key.foregroundColor: color]
        self.navigationBar.tintColor = color
    }

    func backgroundColor(_ color: UIColor) {
        navigationBar.setBackgroundImage(nil, for: .default)
        navigationBar.barTintColor = color
        navigationBar.shadowImage = UIImage()
    }
}

Use the appearance API, and barTintColor color.

UINavigationBar.appearance().barTintColor = UIColor.greenColor()

Swift 5 (iOS 14)

Full navigation bar customization.

// -----------------------------------------------------------
// NAVIGATION BAR CUSTOMIZATION
// -----------------------------------------------------------
self.navigationController?.navigationBar.prefersLargeTitles = true
self.navigationController?.navigationBar.tintColor = UIColor.white
self.navigationController?.navigationBar.isTranslucent = false

if #available(iOS 13.0, *) {
    let appearance = UINavigationBarAppearance()
    appearance.configureWithDefaultBackground()
    appearance.backgroundColor = UIColor.blue
    appearance.largeTitleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.white]
    appearance.titleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.white]

    navigationController?.navigationBar.standardAppearance = appearance
    navigationController?.navigationBar.scrollEdgeAppearance = appearance
    navigationController?.navigationBar.compactAppearance = appearance

} else {
    self.navigationController?.navigationBar.barTintColor = UIColor.blue
    self.navigationController?.navigationBar.largeTitleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.white]
    self.navigationController?.navigationBar.titleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.white]
}

// -----------------------------------------------------------
// NAVIGATION BAR SHADOW
// -----------------------------------------------------------
self.navigationController?.navigationBar.layer.masksToBounds = false
self.navigationController?.navigationBar.layer.shadowColor = UIColor.black.cgColor
self.navigationController?.navigationBar.layer.shadowOffset = CGSize(width: 0, height: 2)
self.navigationController?.navigationBar.layer.shadowRadius = 15
self.navigationController?.navigationBar.layer.shadowOpacity = 0.7

This version also removes the 1px shadow line under the navigation bar:

Swift 5: Put this in your AppDelegate didFinishLaunchingWithOptions

UINavigationBar.appearance().barTintColor = UIColor.black
UINavigationBar.appearance().tintColor = UIColor.white
UINavigationBar.appearance().titleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.white]
UINavigationBar.appearance().isTranslucent = false
UINavigationBar.appearance().setBackgroundImage(UIImage(), for: .any, barMetrics: .default)
UINavigationBar.appearance().shadowImage = UIImage()

iOS 8 (swift)

let font: UIFont = UIFont(name: "fontName", size: 17)   
let color = UIColor.backColor()
self.navigationController?.navigationBar.topItem?.backBarButtonItem?.setTitleTextAttributes([NSFontAttributeName: font,NSForegroundColorAttributeName: color], forState: .Normal)

If you have customized navigation controller, you can use above code snippet. So in my case, I've used as following code pieces.

Swift 3.0, XCode 8.1 version

navigationController.navigationBar.barTintColor = UIColor.green

Navigation Bar Text:

navigationController.navigationBar.titleTextAttributes = [NSForegroundColorAttributeName: UIColor.orange]

It is very helpful talks.

Swift 4, iOS 12 and Xcode 10 Update

Just put one line inside viewDidLoad()

navigationController?.navigationBar.barTintColor = UIColor.red

In iOS 15, UIKit has extended the usage of the scrollEdgeAppearance, which by default produces a transparent background, to all navigation bars. Set scrollEdgeAppearance as below code.

if #available(iOS 15, *) {
        let appearance = UINavigationBarAppearance()
        appearance.configureWithOpaqueBackground()
        appearance.backgroundColor = < your tint color >
        navigationController?.navigationBar.standardAppearance = appearance;
        navigationController?.navigationBar.scrollEdgeAppearance = navigationController?.navigationBar.standardAppearance
    } 

In Swift 2

For changing color in navigation bar,

navigationController?.navigationBar.barTintColor = UIColor.whiteColor()

For changing color in item navigation bar,

navigationController?.navigationBar.tintColor = UIColor.blueColor()

or

navigationController!.navigationBar.titleTextAttributes = [NSForegroundColorAttributeName: UIColor.blueColor()]

Swift 3

UINavigationBar.appearance().barTintColor = UIColor(colorLiteralRed: 51/255, green: 90/255, blue: 149/255, alpha: 1)

This will set your navigation bar color like Facebook bar color :)

Swift 3

Simple one liner that you can use in ViewDidLoad()

//Change Color
    self.navigationController?.navigationBar.barTintColor = UIColor.red
//Change Text Color
    self.navigationController?.navigationBar.titleTextAttributes = [NSForegroundColorAttributeName: UIColor.white]

Swift 3 and Swift 4 Compatible Xcode 9

A Better Solution for this to make a Class for common Navigation bars

I have 5 Controllers and each controller title is changed to orange color. As each controller has 5 navigation controllers so i had to change every one color either from inspector or from code.

So i made a class instead of changing every one Navigation bar from code i just assign this class and it worked on all 5 controller Code reuse Ability. You just have to assign this class to Each controller and thats it.

import UIKit

   class NabigationBar: UINavigationBar {
      required init?(coder aDecoder: NSCoder) {
       super.init(coder: aDecoder)
    commonFeatures()
 }

   func commonFeatures() {

    self.backgroundColor = UIColor.white;
      UINavigationBar.appearance().titleTextAttributes =     [NSAttributedStringKey.foregroundColor:ColorConstants.orangeTextColor]

 }


  }

iOS 10 Swift 3.0

If you don't mind to use swift frameworks then us UINeraida to change navigation background as UIColor or HexColor or UIImage and change navigation back button text programmatically, change complete forground text color.

For UINavigationBar

    neraida.navigation.background.color.hexColor("54ad00", isTranslucent: false, viewController: self)
    
    //Change navigation title, backbutton colour
    
    neraida.navigation.foreground.color.uiColor(UIColor.white, viewController: self)
    
    //Change navigation back button title programmatically
    
    neraida.navigation.foreground.backButtonTitle("Custom Title", ViewController: self)
    
    //Apply Background Image to the UINavigationBar
    
    neraida.navigation.background.image("background", edge: (0,0,0,0), barMetrics: .default, isTranslucent: false, viewController: self)

I had to do

UINavigationBar.appearance().tintColor = UIColor.whiteColor()
UINavigationBar.appearance().barStyle = .Black
UINavigationBar.appearance().backgroundColor = UIColor.blueColor()

otherwise the background color wouldn't change

First set the isTranslucent property of navigationBar to false to get the desired colour. Then change the navigationBar colour like this:

@IBOutlet var NavigationBar: UINavigationBar!

NavigationBar.isTranslucent = false
NavigationBar.barTintColor = UIColor (red: 117/255, green: 23/255, blue: 49/255, alpha: 1.0)

Make sure to set the Button State for .normal

extension UINavigationBar {

    func makeContent(color: UIColor) {
        let attributes: [NSAttributedString.Key: Any]? = [.foregroundColor: color]

        self.titleTextAttributes = attributes
        self.topItem?.leftBarButtonItem?.setTitleTextAttributes(attributes, for: .normal)
        self.topItem?.rightBarButtonItem?.setTitleTextAttributes(attributes, for: .normal)
    }
}

P.S iOS 12, Xcode 10.1

Try This in AppDelegate:

//MARK:- ~~~~~~~~~~setupApplicationUIAppearance Method
func setupApplicationUIAppearance() {

    UIApplication.shared.statusBarView?.backgroundColor = UIColor.clear

    var preferredStatusBarStyle: UIStatusBarStyle {
        return .lightContent
    }

    UINavigationBar.appearance().tintColor = #colorLiteral(red: 1, green: 1, blue: 1, alpha: 1)
    UINavigationBar.appearance().barTintColor =  UIColor.white
    UINavigationBar.appearance().isTranslucent = false

    let attributes: [NSAttributedString.Key: AnyObject]

    if DeviceType.IS_IPAD{
        attributes = [
            NSAttributedString.Key.foregroundColor: UIColor.white,
            NSAttributedString.Key.font: UIFont(name: "HelveticaNeue", size: 30)
            ] as [NSAttributedString.Key : AnyObject]
    }else{
        attributes = [
            NSAttributedString.Key.foregroundColor: UIColor.white
        ]
    }
    UINavigationBar.appearance().titleTextAttributes = attributes
}

iOS 13

func setupNavigationBar() {
    //        if #available(iOS 13, *) {
    //            let window = UIApplication.shared.windows.filter {$0.isKeyWindow}.first
    //            let statusBar = UIView(frame: window?.windowScene?.statusBarManager?.statusBarFrame ?? CGRect.zero)
    //            statusBar.backgroundColor = #colorLiteral(red: 0.2784313725, green: 0.4549019608, blue: 0.5921568627, alpha: 1) //UIColor.init(hexString: "#002856")
    //            //statusBar.tintColor = UIColor.init(hexString: "#002856")
    //            window?.addSubview(statusBar)
    //            UINavigationBar.appearance().tintColor = #colorLiteral(red: 1, green: 1, blue: 1, alpha: 1)
    //            UINavigationBar.appearance().barTintColor = #colorLiteral(red: 1, green: 1, blue: 1, alpha: 1)
    //            UINavigationBar.appearance().isTranslucent = false
    //            UINavigationBar.appearance().backgroundColor = #colorLiteral(red: 0.2784313725, green: 0.4549019608, blue: 0.5921568627, alpha: 1)
    //            UINavigationBar.appearance().titleTextAttributes = [NSAttributedString.Key.foregroundColor : UIColor.white]
    //        }
    //        else
    //        {
    UIApplication.shared.statusBarView?.backgroundColor = #colorLiteral(red: 0.2784313725, green: 0.4549019608, blue: 0.5921568627, alpha: 1)
    UINavigationBar.appearance().tintColor = #colorLiteral(red: 1, green: 1, blue: 1, alpha: 1)
    UINavigationBar.appearance().barTintColor = #colorLiteral(red: 1, green: 1, blue: 1, alpha: 1)
    UINavigationBar.appearance().isTranslucent = false
    UINavigationBar.appearance().backgroundColor = #colorLiteral(red: 0.2784313725, green: 0.4549019608, blue: 0.5921568627, alpha: 1)
    UINavigationBar.appearance().titleTextAttributes = [NSAttributedString.Key.foregroundColor : UIColor.white]
    //        }
}

Extensions

extension UIApplication {

var statusBarView: UIView? {
    if responds(to: Selector(("statusBar"))) {
        return value(forKey: "statusBar") as? UIView
    }
    return nil
}}

I'm writing this for those that still have problems with the solutions here.

I'm using Xcode Version 11.4 (11E146). The one working for me is:

navigationController?.navigationBar.barTintColor = UIColor.white
navigationController?.navigationBar.tintColor = UIColor.black

BUT!, if you set the barTintColor in storyboard to any other value than "default" this 2 lines of code will have no effect.

So, be carefull and set back to default barTintColor in Storyboard. Oh Apple...
