Apple WatchOS 2 Delay caused by Bug in Crucial WatchKit Interface

Apple cancelled the release of the the new WatchOS 2 last minute on September 16. App developers complained about bugs related to the Watch Interface controller just days before release.

Apple killed the planned release of the highly anticipated new WatchOS 2 last minute on September 16. Only iOS 9 was released as planned. As reported, Apple issued a note to the press saying that the company discovered a bug in development of watchOS 2 that is taking longer to fix than expected. The release of watchOS 2 is coming shortly.

It appears that the culprit for the delay is a bug in the crucial watch interface controller. App developers posted problems with functions not being called starting September 13. This was last Sunday. 

The bug is not happening always, which would explain why it takes Apple developer longer to fix. App developer psynixis wrote: "In testing of watchOS 2, GM release, we're finding an intermittent problem where the didAppear method of WKInterfaceController isn't getting called on device. It's pretty random. Maybe 1 in 5 times the method never gets called when the view has appeared."

The WKInterfaceController is the main class for implementing the Watch app interface. Issues in that class prevent the Apple Watch app to correctly render on the Apple Watch.

psynixis said in another post: "To me, it's a clear blocker bug. IMO No way can there be a production release until this bug is fixed.  It will either break apps completely or make them fail intermittently."

Turned out he was right. Apple pulled the watchOS 2 release candidate. There is no word yet from Apple when watchOS 2 will be released. In our earlier report we concluded that the release is going to be next week latest Thursday. 

Apple will not want to release something when all attention is on the iPhone 6S sales launch on Friday, September 25.

The new Apple WatchOS adds the crucial native app support. This allows app developers access the sensors on the Apple Watch and work without the iPhone. There are new Watch faces and the new Time-Lapse watch face that shows time-lapse videos shot over 24 hours in iconic locations around the world.

Apple also allows users to customize Watch faces with compilations to display the state apps at all times. Another cool new feature is Time Travel. With Time Travel, users can turn the Digital Crown to see what’s happening and what’s already happened yesterday, today, and tomorrow. Users can see what the weather will be like for a lunch date in a few hours or checking the schedule for tomorrow.

The night stand feature coming in WatchOS 2 turns the Apple Watch into a neat little alarm clock.
