Just created a Today Widget and all seems to be good (on ios 8.3) devices. It installs and runs fine from XCODE 6.3.1. But on iOS 8.2 or 8.1 devices, the Today Widget does not install / run even though XCODE says it is running.
If a breakpoint is put on ViewDidLoad it never gets hit. Will try and do some digging in the logs, but so far nothing...
