Cocoapod add VALID_ARCHS but it's discouraged in Xcode 12

Hello,

From Xcode 12 release notes:

The Build Settings editor no longer includes the Valid Architectures build setting (VALID_ARCHS), and its use is discouraged. Instead, there is a new Excluded Architectures build setting (EXCLUDED_ARCHS). If a project includes VALID_ARCHS, the setting is displayed in the User-Defined section of the Build Settings editor. (15145028)

I have test to x86_64 for simulator only, test to exclude amd64 in both project and pod project... Sometimes it works but it depend on the project.
I have few prject, the only workaround that works 100% is to remove VALID_ARCHS line in the file located in the Pods/Targets Support Files/ Pods-(projectname)/Pods...xcconfig. Both in debug and release on the last line.

No need to exclude arm64 when there is no more VALID_ARCHS everywhere. It's very clean.

Is there a way to prevent pod update to not add this line or can cocoapod pubish a update to no more add this line in latest version of cocopod ?

Where does CocoaPods "add" VALID_ARCHS? Nothing in the code search shows it.

I think this is a dup of CocoaPods/Xcodeproj#784

After you told me it wasn't Cocoapod I searched for installed pods and found it was in a lot of pods like Mopub, Applovin... I guess if it is in the xcconfig of one of them it is also put in the xcconfig of the general Pod.

It is especially when the target is on IOS 9, from ios 10 it is no longer in it for Mopub, maybe it still is for others who have not fixed that.

Can Cocoapod check this line and delete it automatically, maybe with a script to add in the Podfile?

We need to figure out how to support both for Xcode 11 transition and Xcode 12 with the new way. I still think the issue is in Xcodeproj.

Use a post_install hook to delete VALID_ARCHS from the Pods.xcodeproj.

Yes a post_install but i don't know where i can find detailed docs.
Maybe you can give me a sample to do that ?

add x86_64 in VALID_ARCHS

add x86_64 in VALID_ARCHS

If you read my first post i say it's not a universal solution. post_install hook would be nice but i don't know how to write it

Fix all configuration

target 'Demo' do
  post_install do |installer|
    installer.pods_project.build_configurations.each do |configuration|
      installer.pods_project.build_settings(configuration.name)['VALID_ARCHS'] = []
    end
  end
end

Fix one configuration, like Debug

target 'Demo' do
  post_install do |installer|
    installer.pods_project.build_settings('Debug')['VALID_ARCHS'] = []
  end
end

I am not seeing a thing we can do here for CocoaPods per se.

If a podspec uses s.user_target_xcconfig then that this strongly discourages as the docs say and you have to delete it yourself via post_install hook.

CocoaPods does not set VALID_ARCHS in your project, only uses it for read-only during lint which we have other issues filed for.

I am going to close this for now. I will re-open if I have misunderstood something or new information shows we need to change something.
