Swift standard libraries embedding explicitly set to NO by CocoaPods

[wiedem]

Report

What did you do?

Include ObjC only pod libraries in your project, project uses a custom Swift framework not managed by CocoaPods.

What did you expect to happen?

CocoaPods should not explicitly set the ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES to NO inside the xcconfig files if it thinks no Swift runtime library is needed. Actually it should not set this option at all if it determines no Swift runtime is needed by the pods and thus leave it up to the project settings. Or there should at least be an option to tell CocoaPods that the Swift runtime libraries are needed even though it is not able to detect the requirement.

What happened instead?

CocoaPods automatically sets the ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES to NO inside the xcconfig files and shows a warning

[!] The `Test [Debug]` target overrides the `ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES` build setting defined in `Pods/Target Support Files/Pods-Test/Pods-Test.debug.xcconfig'. This can lead to problems with the CocoaPods installation
    - Use the `$(inherited)` flag, or
    - Remove the build settings from the target.

Having a similar issue... except our app actually uses Swift 2.3 and it is still setting ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES to NO

[benasher44]

@grioja this is because of a target that has Swift that isn't managed by CocoaPods as well?

However I'm facing the exact issue i'm using audiokit that is build with swift as ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES set to no the crash pops
NO image found and when i set ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES to YES the size of the app is ridiculously increased is there any way i can set ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES to yes and still persist the size of my app because im using Objective-C any suggestions... @benasher44 @wiedem @grioja @kommen @ericallam

[benasher44]

If you use any Swift pods, then you'll have to have that set to YES, which means you'll have to have the Swift standard libraries bundled with your app (increases app size).

Unfortunately no. Using Swift in your app or using any framework written in Swift currently means the Swift standard libraries need to be copied into your app bundle (just like @benasher44 said).

Your only option is to not use frameworks written in Swift - that is until Apple makes the Swift ABI stable and ships iOS with the Swift standard libraries.

@DreamBegin What is the increase in size?

[tryWabbit]

the size of the ipa that was 32mb (31 mb was consumed by the soundfonts that i've used in the app that is no issue) and now 60mb. @srameshr

[deliverymanager]

Did you find a solution on the size app increase?
I am having the same issue with a cordova/ionic build

[srameshr]

@deliverymanager It does not matter. Because, once you upload it to the app store, the size of ipa that is served is decreased significantly.

[deliverymanager]

I am not sure about that.
Could you please tell the me exactly the numbers in your case?
From 60MB where did you end up?

@srameshr Thank you very mush for your response!

Is there any way to silent it?
I mean, the warning:

[!] The `MyApp [Debug]` target overrides the `ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES` build setting defined in `Pods/Target Support Files/Pods-MyApp/Pods-MyApp.debug.xcconfig'. This can lead to problems with the CocoaPods installation

We just don't support iOS 12.1 or earlier, any workaround is appreciated.
If it's not possible yet, should I create a feature request?

P.S. iOS is about 100 years behind Android (if not set the theme without 3rd-party library, or custom code).
