Workaround - override willActivate and call setTitle there. After setTitle is called in willActivate, setTitle will start working elsewhere in the program. I have a multi-page watch app with same issues described above.     // Bug with WatchKit, in order for the UI     // to honor setTitle calls later in the     // program, you need to call setTitle here first     // Only need if you have multiple pages     override func willActivate() {         self.setTitle("")         super.willActivate()     }
