The Apple community, clearly. I don't know a single mobile dev who would trade Android Studio for Xcode with a smile, but then again I don't live on the West Coast.
I prefer Xcode to Android Studio. It feels a bit snappier than JetBrains IDEs to me and I find the interface to be more intuitive. The iOS simulator outperforms the Android emulator and Gradle is by far the worst build system I’ve ever used.
