Attention

I found a solution on stack overflow which is to add EXCLUDED_ARCHS[sdk=iphonesimulator*] = arm64 x86_64;
to the pod that is breaking ios/Pods/Target Support Files/RNIap/RNIap.debug.xcconfig and the build passed, so the CTO asked to request to open this issue to see what is the most efficient solution to this problem so that we don't have to create a fork of the library and fix the problem or create a patch of the pod.

Thanks!!

Could you please test the example project in the repo and compare it with your setup? I suspect the issue is not related to our library, but more likely due to react-native dependencies. 🤔

cc @arthurgeron, the contributor for LatestPromiseKeeper, just in case.

When I run npx -y eas-cli build --platform ios --local --profile development on my local machine (Apple M1), I get the following error:

[RUN_FASTLANE] The following build commands failed:
[RUN_FASTLANE] 	SwiftCompile normal arm64 Compiling\ LatestPromiseKeeper.swift /var/folders/2q/rxlt_3q965s8jrck6jhr3fbh0000gn/T/eas-build-local-nodejs/0c1b1855-768b-4e8a-8d0b-c246c27612a5/build/node_modules/react-native-iap/ios/LatestPromiseKeeper.swift (in target 'RNIap' from project 'Pods')

This command was working before upgrading react-native-iap from 12.13.2 to 12.15.1. It also still seems to work on non-M1 machines.
