java.lang.RuntimeException when building for multiple archs an ios_application that depends on an apple_framework

[vakhidbetrakhmadov]

Hi,

When building an ios_application from rules_apple that depends on an apple_framework, following error occures:

$ bazelisk build --apple_platform_type=ios --ios_multi_cpus=x86_64,sim_arm64 --//:test_case=apple_framework HelloWorldSwift

FATAL: bazel crashed due to an internal error. Printing stack trace:

I have created a minimal repro example that can be found here: https://github.com/vakhidbetrakhmadov/ios_multi_cpus_repro.

To reproduce the error above, please run bazelisk build --apple_platform_type=ios --ios_multi_cpus=x86_64,sim_arm64 --//:test_case=apple_framework HelloWorldSwift.

As a comparison, when apple_framework is replaced with swift_library, it compiles just fine.

To observe that, please run bazelisk build --apple_platform_type=ios --ios_multi_cpus=x86_64,sim_arm64 --//:test_case=swift_library HelloWorldSwift.

Same is true when compiling for a single arch.

To observe that, please run bazelisk build --apple_platform_type=ios --ios_multi_cpus=x86_64 --//:test_case=apple_framework HelloWorldSwift or bazelisk build --apple_platform_type=ios --ios_multi_cpus=sim_arm64 --//:test_case=apple_framework HelloWorldSwift.

I'm going to close this in favor of bazelbuild/rules_apple#2518, thanks for investigating the issue though!
