iOS 8 requestWhenInUseAuthorization no Popup

Question

I tried to make my AppProject iOS 8 ready. I had read a lot about

[_locationManager requestWhenInUseAuthorization];

and the entry in plist<

Answer 1

Pertaining to the Apple Watch:

You need to put the requestWhenInUseAuthorization key in the iPhone's Info.plist, not the WatchKit App's.

This has bitten me twice now.
