iOS Simulator build fails: Sentry.embeddedframework.zip is device-only

[microneo]

Environment

How do you use Sentry?
Self-hosted

Which version of the SDK?
1.12.0

How did you install the package?
Git-URL

Which version of Unreal?
5.6/5.7

Is this happening in Unreal (editor) or on a player like Android, iOS, Windows?
iOS Simulator

Steps to Reproduce

1. Add Sentry plugin to an Unreal 5.7 project
2. Build for iOS Simulator:
   Engine/Build/BatchFiles/Mac/Build.sh ProjectName IOS Development -Project=ProjectName.uproject -Architecture=iossimulator

Expected Result

Project compiles successfully for iOS Simulator.

Actual Result

Linker error:
ld: building for 'iOS-simulator', but linking in dylib (.../UnzippedFrameworks/Sentry/Sentry.embeddedframework/Sentry.framework/Sentry) built for 'iOS' clang++: error: linker command failed with exit code 1

Sentry.embeddedframework.zip contains only an arm64 iphoneos slice - no simulator slice is included.

A fix is already prepared: microneo@4ef048d

Happy to open a PR if this approach looks good.

I made some minor changes, and it builds successfully on UE 5.7.

However, there is still one more issue: UE5 has two build bugs for the iOS simulator. I’m working on fixing them as well. They are not major, and I’ll try to provide a patch for UE 5.7 today that fixes this problem. I will also submit a PR to Epic Games.
