No, it compiles LDC and druntime/Phobos on macOS using cross-compiling. 
Cross-compiling is the official way you compile apps for iOS devices. 
You don't have permission to create a new process (fork) on iOS devices 
so a compiler running on iOS is not possible.

They support running on physical devices:

"With Bitrise’s iOS device testing solution, you can run iOS tests on 
physical devices without having to set up and register your own devices"

"Our device testing solution is based on Firebase Test Lab: it uses 
real, production devices running in a Google data center to test your app"
