In Xcode version 16.2 (16C5032a) I created:

One [ScenekitApp] [File/New/Project/iOS/Game/Game Technology: SceneKit].

Three custom Frameworks [File/New/Project/iOS/Framework] [ASCSource.framework, ASCCommon.framework and ASCCoreData.framework].

In the four projects the [Minimum Deployments=iOS 15.0], [Swift version=6.0] and [BUILD_LIBRARY_FOR_DISTRIBUTION=Yes].

I directly installed the [Zip.framework] in [ASCSource.framework] without [pod init/pod install] and in the [General tab] [Frameworks, Libraries and Embeded Content] [Zip.framework Embed&Sign].

I installed the three frameworks [ASCSource.framework, ASCCommon.framework and ASCCoreData.framework] in [ScenekitApp] and everything works perfectly in Xcode version 16.2(16C5032a).

I updated Xcode version 16.2(16C5032a) to Xcode version 16.3(16E140) and some errors in the SDKs were indicated.

[Failed to build module 'ASCSource'; this SDK is not supported by the compiler (the SDK is built with 'Apple Swift version 6.0.3 effective-5.10 (swiftlang-6.0.3.1.10 clang-1600.0.30.1)', while this compiler is 'Apple Swift version 6.1 effective-5.10 (swiftlang-6.1.0.110.21 clang-1700.0.13.3)'). Please select a toolchain which matches the SDK].

[Failed to build module 'Zip'; this SDK is not supported by the compiler (the SDK is built with 'Apple Swift version 6.0.3 effective-5.10 (swiftlang-6.0.3.1.10 clang-1600.0.30.1)', while this compiler is 'Apple Swift version 6.1 effective-5.10 (swiftlang-6.1.0.110.21 clang-1700.0.13.3)'). Please select a toolchain which matches the SDK].

If I recompile all frameworks in Xcode version 16.3 (16E140) it will work, but I don't think it will be a good solution.

I found some discussions in links like the following without success.

Any help is welcome.

Thanks everyone!!!

This is expected behavior for frameworks that are not compiled with ABI resilience enabled. Resilience interferes with cross-module optimizations, so it is not enabled by default.
