I'm doing this:@implementation RootViewController static CHHapticEngine *hapticEngine API_AVAILABLE(ios(13.0)); static CHHapticPatternPlayer *hapticPlayer API_AVAILABLE(ios(13.0));But Xcode reports an error on the third line: "Unknown type name CHHapticPatternPlayer, did you mean CHHapticPatternKey?"Further in my code I have this line:hapticPlayer = [hapticEngine createPlayerWithPattern:pattern error:NULL];And there Xcode says this error: "Assigning to 'CHHapticPatternKey *' (aka 'NSString **') from incompatible type 'id<CHHapticPatternPlayer> _Nullable'"Of course the pattern was first successfully initialized (code omitted here for clarity).Might this issue be a bug in the framework?
