This is a useful workaround. Note that the underscores are missing: #define LOG(fmt, ...) { NSString* strDebug; strDebug = [NSString stringWithFormat:(fmt), VA_ARGS]; NSLog(@"%@", strDebug); }

Having this problem with Xcode 13.3. Quit the app store, threw away the Xcode app, and restarted the app store. Now I am seeing a progress circle, and it is progressing, though pretty slowly. Ticked me off: I was all ready to code when this happened.
