Xcode 12 ships with both Intel and Apple Silicon tooling, so you can use our Xcode 12 image to build Intel, Apple Silicon and Universal apps.
There are a few caveats to note:
- Compilation times for Apple Silicon will be elevated due to the overheads of cross-compiling.
- Testing Apple Silicon apps is not possible as our fleet is entirely comprised of Intel Macs
CircleCI is planning to add Apple Silicon hosts to out fleet in the future, however we do not have an ETA for this.
