Device.swiftmodule is not built for arm64

[zakray]

After installing Device via swift package, I'm unable to run my app via the simulator. I get "Build failed because Device.swiftmodule is not built for arm64, please try a run destination with a different architecture". After I got that error, a new simulator option with Rosetta appeared, but trying to build on that gave me a number of errors about "undefined symbol".

It does work fine on a real device. This is running latest macOS with Xcode 16 on an M2 Mac. Any ideas?

The problem was caused by duplicating the Device library dependency in my project. I had added https://github.com/kudit/Device.git (v2.6.1) in two places:
1. Directly in my project’s target.
2. Indirectly as a dependency of a private package.

This resulted in the library being included twice in the same project, causing conflicting symbols and undefined symbol errors.

To resolve the issue, I removed the direct reference to Device from my project since it was already included via my private package’s dependencies. This eliminated the duplication, and the errors were resolved.
