How to build skia for iOS simulator on an M1 mac

[Luis Grimaldo]

Hi,

I am able to build an iOS device build and an iOS simulator build but only for x64 systems (intel macs) by passing in the hint target_cpu = "x64" and target_os = "ios". However, with the new Apple Silicon M1 chips, the simulator now runs on arm64. Is there a workaround to build an arm64 iOS simulator build and/or is there an issue filed for this?

Thanks.

That's a good point -- I don't think we've dealt with that yet. I've filed a bug: https://bugs.chromium.org/p/skia/issues/detail?id=13098

This bug also discusses the same issue, and I've also added a few comments on how I solved it:

I've just landed a CL that adds a new gn argument: ios_use_simulator. Set that to true and target_os to "ios" and you should be able to run the simulator on M1 Macs. Let me know (via https://skbug.com/12880) if there are any further issues.
