Support for arm64 architecture in XCode

[Anna Thomas]

Hi, 

I'm writing this with respect to the my project that is currently using Tink 1.6 and XCode 15.4. We've included Tink as a cocoapods. But currently we're facing an issue wile trying to include arm64 in the build settings.

Is there a known limitation with the Tink library that prevents it from running on an ARM64-based simulator? The app runs fine on the simulator using Rosetta, but fails on the native ARM64 version. I'd like to understand why the library doesn't support the native environment. Also, will the support be available in any of the future versions ? 

Thanks for the amazing library!
