I use CocoaPods to manage dependencies in my project. I've written Podfile:
target 'MyApp' do
platform :ios, '8.0'
# Uncomment this line if you're using Swift or would like to use dynamic frameworks
#use_frameworks!
# Pods for MyApp
pod 'KeepLayout', :git => 'https://github.com/iMartinKiss/KeepLayout', :tag => 'v1.6.0'
pod 'EasyMapping'
target 'MyAppTests' do
inherit! :search_paths
# Pods for testing
end
target 'MyAppUITests' do
inherit! :search_paths
# Pods for testing
end
end
This file works well with CocoaPods 0.x but I can't compile project after I've updated to CocoaPods 1.0. After I've run
pod update
I can't compile my project with error:
/Users/<...>/Pods/KeepLayout/Sources/KeepAttribute.m:195:1: Cannot synthesize weak property because the current deployment target does not support weak references
I've seen that every library is builded with different deployment target. For example KeepLayout is builded with 4.3 deployment target.
How I can determine build target for every pod dependency?
pod update is setting the deployment target of the pod to iOS 4.3 because that is the default deployment target if the podspec doesn't specify one. This was an intentional decision by the CocoaPods team, even though it breaks some older pods that basically have an incomplete podspec. If you are maintaining the pod, you should specify an appropriate target, e.g. platform :ios, '8.0' to fix it. If you are just trying to use a pod that is broken in this way, please try my suggestion below.
While some development versions of CocoaPods (as well as pre-1.0 versions) may have propagated the deployment target of the project down to the pods, this is no longer the case in 1.0. To work around this, the current developer recommends using a post-install hook.
Here's a brute force approach to force a hard-coded deployment target for every pod in the generated Pods project. Paste this at the end of your Podfile:
post_install do |installer|
installer.pods_project.targets.each do |target|
target.build_configurations.each do |config|
config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '9.2'
end
end
end
Since the Podfile uses a directive like platform :ios, '9.0' to specify "iOS Deployment Target" (aka IPHONEOS_DEPLOYMENT_TARGET) for the Pods/Pods.xcodeproj project, you just need to remove the Deployment Target info from each build target.
Do it by adding this to your Podfile
platform :ios, '9.0' # set IPHONEOS_DEPLOYMENT_TARGET for the pods project
post_install do |installer|
installer.pods_project.targets.each do |target|
target.build_configurations.each do |config|
config.build_settings.delete 'IPHONEOS_DEPLOYMENT_TARGET'
end
end
end
Inspired by the github post and Alex Nauda's answer.
Podfile
While the accepted answer by Alex Nauda is good, but letting the Pods inherit the target from the app might be a much better solution. 🚀
app_ios_deployment_target = Gem::Version.new('9.2') # Change to your current deployment target
platform :ios, app_ios_deployment_target.version
# Let Pods targets inherit deployment target from the app
# This solution is suggested here: https://github.com/CocoaPods/CocoaPods/issues/4859
post_install do |installer|
installer.pods_project.targets.each do |target|
target.build_configurations.each do |configuration|
pod_ios_deployment_target = Gem::Version.new(configuration.build_settings['IPHONEOS_DEPLOYMENT_TARGET'])
if pod_ios_deployment_target <= app_ios_deployment_target
configuration.build_settings.delete 'IPHONEOS_DEPLOYMENT_TARGET'
end
end
end
end
Here is the way to set deployment target permanently for pod targets.
Goto -> podfile -> Add below code
post_install do |installer| installer.pods_project.targets.each do |target| target.build_configurations.each do |config| config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = "12.0" end end end
change target to "11.0"
platform :ios, '11.0'
1) Search for IPHONEOS_DEPLOYMENT_TARGET
2) Change the iOS Deployment Target

'9.2'with whatever deployment target you would like to use.IPHONEOS_DEPLOYMENT_TARGETfrom every target settings? Project already set its deployment target, and every target just inherit it.
