title: Watchkit app showing error during installation - The WatchKit app has an invalid stub executable
body: <p>I have an app that supports Watchkit. When I run the application onto the iPhone, it builds fine but displays an alert in Xcode &quot;<strong>The WatchKit app has an invalid stub executable</strong>&quot;. I have used the bundle identifier properly and installed the provisioning profiles and certificates properly as well. Any clue on this, please?</p>
  <p>Pls note that I am building this project in Xcode 10.3 as the included frameworks are still in Swift 4.2 and couldn't be upgraded to Swift 5.</p>
