Add support for Apple Silicon (arm64) to iOS Simulator builds

I have the same issue. Has anyone found a workaround?

@sdnsepehr

Try running Xcode with Rosetta enabled

Is there a way to change the settings to build for arm_64 simulator?

Not if you link any binary that does not have an ARM64 slice for the simulator.

Google provides two versions of the SDK now:

• v7.1.0 in form of legacy fat frameworks (without support for ARM64-simulator)
• v7.1.0-beta in form of XCFrameworks (with ARM64-simulator support)

There are two problems:

• This project is using v7.1.0 (so, no ARM64-simulator support)
• v7.1.0-beta does have ARM64-simulator support, but for some reason can't be used as a Swift Package dependency (it builds but app fails to start)

Here is my (experimental) solution: https://github.com/darrarski/GoogleMaps-SP

It can be used as a dependency of Swift Package and provides ARM64-simulator support (without running through Rosetta).

Enjoy, I hope it helps :-)

The problems with Google's XCFrameworks are:

• They don't contain an Info.plist file.
• They binary inside is a static library rather than a dynamic library.

That's true. I think there's no other way around than to use them if we need ARM64 simulator support at the moment.

My approach is to rebuild the XCFrameworks using (slightly modified) script from this repo and thin frameworks contained inside Google's official XCFrameworks. A bit hacky, but works for me (in simulator on M1 and on a physical device).

Hopefully Google will fix their frameworks, so we can use them directly.

I tried embedding Google's XCFrameworks inside this repo XCFrameworks and it was a success, one problem was The framework name need to be different than Google's framework names to prevent linking collisions i.e renaming GoogleMaps.framework to GoogleMaps_.framework (either Google's one or this repo one).

I tried embedding Google's _XCFramework_s inside this repo _XCFrameworks and it was a success, one problem was The framework name need to be different than Google's framework names to prevent linking collisions i.e renaming GoogleMaps.framework to **GoogleMaps.framework** (either Google's one or this repo one).

Not sure I understand the name collision issue. You can store GoogleMaps.framework for the device and GoogleMaps.framework for the simulator in separate directories... or just use GoogleMaps.xcframework from Google, which contains both (as I did).

@darrarski Thank you so much for sharing the code! I've been trying to reverse engineer the whole process (creation of Xcode projects, setting up dependencies). Could you please share how you setup linking between GoogleMaps & GoogleMapsBase & GoogleMapsCore? I'm now stuck at Undefined symbols for architecture arm64 😕

[darrarski]

I didn't do anything special here. Started by forking this repository and duplicating the Xcode project to have two of them. One is using ".framework" files for physical devices and second for simulators. I've got these frameworks from official XCFramework file downloaded from Google (ver. 7.1.0-beta). That's it.

Thank you! I’ll try the same!
