Xcode 9 error: "iPhone has denied the launch request"

It may be code sign issue. Make sure you're signing with developer, not distribution.

---

It happens using Xcode 9.x or newer.

I tracked this problem down to the "debug executable" checkbox in the product scheme (product->scheme->edit scheme->info->debug executable checkbox). I unchecked that and this stopped happening (as well as a couple other weird issues - no output in console being one).

---

I have a workaround: If you change the scheme to 'Ask on Launch' it works.

In Xcode top bar

Product > Scheme > Edit Scheme > 'Info' tab > Executable:  "Ask on Launch"

It's slightly annoying but it works.

---

This issue can be resolved by unchecking Debug Executable in Edit Scheme.

After getting "denied launch request" error, do this:

Edit Scheme -> Info -> Executable -> Ask on Launch

This worked for me with adhoc profile.

---

The problem for me was that I was using a free developer account (simply signed in with my Apple ID). When looking at the device logs I found (bold added)

(RequestDenied); reason: "The request was denied by service delegate (SBMainWorkspace) for reason: Security ("Unable to launch {com.my.bundleID} because it has an invalid code signature, inadequate entitlements or its profile has not been explicitly trusted by the user")"

That made me realize that I needed to go into Settings -> General -> Device Management -> {My Apple ID} -> Trust

After that, everything worked as expected.

In previous versions of iOS I would encounter a dialog on my device that would tell me that this was the problem. Maybe Apple took it out for iOS 11. 🤔

---

Simple restarting of the iPhone helped me out.

---

For me issue was due to code signing the app with Ad hoc profile.

After changing the code signing to developer profile,from xcode settings general tab the above issue got resolved.

---

I got this issue recently and I found the solution for this crazy issue. This are the Scheme Issue to fix this issue follow following steps.

Click Edit Scheme top Navigator Tab.

Click Info on Run menu. On Executable dropdown select "Ask on Launch" option -> Then Close and run the build once.

This solved my problem when I got this issue.

Apple Reference

Got this with Xcode 9.0 while deploying to a non-simulated iPhone 6s with iOS 10.3.

I had force-quit the app right before this arose. Otherwise, nothing had changed; all the developer signing credentials was still trusted, and the app was still marked Verified in the iPhone's Settings.

The trick that fixed it was turning the iPhone off and then turning it back on again.

Looking at my logs, it appears applicationWillTerminate was triggered a while before this happened; the instance of the app that I thought I force-quit must have been some zombie process?

---

The problem is that xcode 'times out' after certain seconds. The fix is to edit the scheme and ask xcode to 'wait' until the executable is launched.

In Edit Scheme, check 'Wait for executable to be launched' instead of 'Automatically'

---

I attentively read all answers but they don't help me. My solution:

Go to Xcode preferences, select accounts (⌘ + ,) Select your Apple ID, choose team and click Manage Certificates In Pop up menu in bottom left corner click + button and select iOS Development, then click done and close popup Try to relaunch application, now it's should fine.

---

It may cause with switched a wrong branch with Git, Make sure the branch you switch not too old(since it may cause code sign issue), And on the right branch if this still bothering, select the development Provisioning Profile under Signing(Debug) if u r not Automatically manage siging.

---

Just tick "Automatically manage signing" in General -> Signing properties of the Target. It will create Development provisioning profile for you and running on the device will work.

---

These simple steps helped me.

Remove your connected iPhone, iPad from the mac. Restart your device. Select "Automatically manage signing" in Xcode settings. Reconnect your iPhone, iPad.

I know there are lots of answers in this thread. I've tried every one of them but none worked for me.

TLDR:

Here is the solution:

Update to xcode 11.4.1 or newer

Going through all the certificates in Keychain access I found out that all of my developer certificates has a invalid status. And, I believe that, this is the root cause of this issue. I've tried the solution here saying delete Apple Worldwide Developer Relations Intermediate Certificate and everything. But, It didn't work.

Then I came across this link. Apparently, the Apple Worldwide Developer Relations Intermediate certificate (AWDRI) is set to expire in 2023 and developer certificates or any other certificates issued after January 28, 2021 won't be using that particular AWDRI certificate. Instead of that they use a renewed certificate which is set to expire in 2030. And here comes the problem, The new renewed certificate only works in xcode versions of 11.4.1 or newer. And, I have an older version of xcode.

When I updated my xcode to latest version - 12.4 (I had to go through making space on my machine, updating macos and all) The problem went away. All my developer certificates on Keychain access are now showing valid. And, I could see two AWDRI certificates on my Keychain access one expiring on 2023 and another one in 2030.

Description from the link I shared:

The current Apple Worldwide Developer Relations Certification Intermediate Certificate (intermediate certificate) is set to expire on February 7, 2023. The renewed certificate will be used to sign new software signing certificates issued after January 28, 2021 for the Apple Developer Programs. Remaining service certificates will be updated in the future and this page will be updated to reflect additional certificate changes.

And more...

This requirement also impacts all software signing certificates generated after January 28, 2021, by developers with Personal accounts in Xcode, as well as members of the Apple Developer Program, Apple Developer Enterprise Program, and iOS University Developer Program.

The new Apple Worldwide Developer Relations Intermediate Certificate is downloaded automatically by Xcode 11.4.1 or later and is available for download on the Certificate Authority page. Confirm that the correct intermediate certificate is installed by verifying that the expiration date is set to 2030.

Also they are mentioning about an issue with older versions:

Xcode 11.4.0 and earlier may not be able to sign software using signing certificates issued by the new Apple Worldwide Developer Relations Certification Intermediate Certificate. If you’re unable to upgrade to a supporting version of macOS or Xcode on your build machine, you can build and archive your app using an earlier Xcode client and sign it for distribution using the latest release. Alternatively, you can utilize the codesign tool to sign your software using the command line.

I face this issue on Xcode 9.1

Scenario: I checked "Connect via Network" option for device. And trying to run app to this device with USB cable attached.

Fix: Simply remove USB cable and run.

I'have tried all the answers nothing worked for me, The problem is coming form Xcode itself and has nothing to do with profiles and certificate :

Product > Scheme > Edit Scheme

In Run (Section) / info (tab) [select] the Release instead of debug as Build Configuration as follow :

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

It's a regression since Xcode 10.1

Config : Xcode Version 10.1 (10B61) Iphone X / IOS 12.1.4

---

I had the same issue . Its a bug in Xcode 9.1. There is a trick to make it work for now. Lock your phone. Run the code. Xcode will ask to unlock the iPhone.

---

I just cleared the profiles with the Apple Configurator, restarted the iDevice and worked again as usual.

---

It's an intermittent bug in Xcode - I just stopped and started all my devices and it magically worked (after messing about for 1/2 hour) I had upgraded MacOS overnight to 10.13.04 which obviously upset something! Xcode 9.3, iOS 11.3 watchOS 4.3

---

Let me tell you a workaround which solves my problem:

Step 1: Windows > Devices and simulator.

Step 2: Unpair device.

Step 3: Reconnect device and trust.

Step 4: Run the application. BINGO.

---

For me this issue was related to a Manually installed Enterprise Certificate and having to use it for both development and release schemes. I had to trust the certificate on the device before it would allow the app to be launched, but it would never launch as I kept getting that denied message. Eventually, editing the scheme and setting it to wait for the app to be attached before debugging did the trick.

Open the App Groups in Capabilities, wait App... effective，then close the App Groups, it worked:

After seeing all the solutions given across web, i finally found one and here are those:

Error occurs because of it makes Runner confused about what profile to use.

You will most often get this error, when you have added new account in profile in Xcode > Targets > Signing.

You can remove this error by just using before one Profile.

There is no need to create New Users.

or you can sign in with account you are using in Profile in your iPhone (i did this!)

Happy Days :)

In case this problem occurred for you a couple of days before today, 2019-Mar-20, it is very likely related to the fact that faulty code signing certificates were issued. In that case you should be able to resolve it by just recreating the code signing certificate. This SO question already has an answer that explains you how to do so.

---

I'm not sure whether it's a fix, or just another workaround, but uninstalling the application from my device helped. I'm still not sure what caused it, but @MrRogers answer helped me figure it out.

---

For me the issue came-up because, I was using the Distribution Provisioning Profile to debug.

We cannot debug with Distribution Provisioning Profile, changing it to Development Provisioning Profile fixed the issue.

Steps: (Xcode 11.2.1)

Select Project, Under TARGETS, select the correct target. Switch to Signing & Capabilities Under Singing section, change the Provisioning Profile to Development profile or you can just check Automatically manage signing

None of the other answered worked -

Xcode 11+

Click Edit Scheme on the top Navigator Tab. Launch option choose Wait for executable to be launched

You will have to run the application on your device manually but that will keep the debugger attached as for some of the other solutions debugger get detached.

Today,I also meet this question.This is my way to solve. Xcode 9.0,iPhone 6s,Automatically manage signing with my account. When I select "iPhone 6s",I found that there is an logo after the iPhone 6s It's the new function of Xcode 9.0 that can run an app on the iPhone without a string connect computer(iPhone and Mac must connect the same Network). So, I try to change this kind of connect way. Open "Devices and Simulators"-> unselect "Connect via network" And then, I clean, rebuild and run my project.It works! I will be happy if this method can help you.
