Answer 1

I am also facing this issue for very long time and after trying all the suggestions given in the different portals, i came to know that the issue is with the device you want to run the application. Device have latest iOS and your Xcode is not supporting that iOS.

For example you have Xcode 7.2 and want to run the application on device which have iOS 9.2.1. So you only need to update your Xcode.

And one more thing Base Sdk in Build Settings is always greater or equal to the software version number on your development device.
