I've updated my test device to use the latest iOS Beta (8 I believe), and I still cannot get it to appear either in the widget library or even on the home screen upon running it from Xcode. But it works totally fine on Simulator. Any ideas what's going on here?
Why can I test Widget on simulator but not physical device?
Figured it out - needed to run the main target scheme, not the widgetextension scheme, oddly enough.
