I dont understand the issue. You can use a post install hook to change the deployment target.

Please upload a sample app as well.

• i know, but cocoapods is not make dir, case target os version < Simulator os version

• case 1 :

  • My Project - iOS Deployment Target : 8.0
    -> not make dirs (FirebaseCore , FirebaseCoreDiagnostics ...)
    -> i want iOS Deployment Target : 8.0 , iOS Simulator iPhoneX (11.2)
    -> pods is not make

• bug sample

  • https://github.com/masteage/CocoaPodsTestSample

• "Build Active Architecture Only = NO" case is not build pods
  Build Active Architecture Only = NO; ONLY_ACTIVE_ARCH = NO;

[ArtFeel]

Add this to your Podfile

# Pods build settings configuration
# optimisations and warning fixes
post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      # Fix for XCode 12
      config.build_settings.delete 'IPHONEOS_DEPLOYMENT_TARGET'
    end
  end
end

thanks @ArtFeel ,
but not fixed....

• sample code (branch - bugfix/test_01)

If I'm understanding this issue correctly, it's that, for Xcode 12, which is now in general release, every pod will issue this warning on compile:

warning: The iOS Simulator deployment target 'IPHONEOS_DEPLOYMENT_TARGET' is set to 8.0, but the range of supported deployment target versions is 9.0 to 14.0.99. (in target 'IAMenuController' from project 'Pods')

Do I have this right?

If so, it seems to me that, while the post_install workaround is most welcome, it should not be required as SOP, and that this still needs to be fixed.

True?

@claybridges It should be fixed in the podspec's. Fixing in CocoaPods is a potential breaking change. See the discussion at https://github.com/CocoaPods/CocoaPods/issues/9884

[paulb777]

Or it should be fixed in Xcode. See the discussion at https://forums.swift.org/t/minimum-ios-version-xcode-12-and-build-warnings/40224

[claybridges]

@paulb777 Got it. Thanks for taking the time to explain this.

[dnkoutso]

Shall I close this? Is it the same issue regarding deployment target 8.0 warnings?

[paulb777]

Yes. I believe it's the same.
