@eskimo, I've filed a feedback for this as well with a very small sample project demonstrating the compiler crash. FB10692950

This is still happening with beta 4.

I'm getting the similar error on the iOS simulator, both with beta 3 and beta 4. Similar thread here: https://developer.apple.com/forums/thread/709807 In my case, the error code is 0: [WeatherService] Encountered an error when fetching weather data subset; location=<+41.16107900,-104.80545000> +/- 5.00m (speed -1.00 mps / course -1.00) @ 7/27/22, 1:38:11 PM Mountain Daylight Time,  error=Error Domain=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=0 "(null)"
