I tries a lot but couldn't solve it.

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.

Answer 2

This error happened to me when I accidentally modified the uikit framework. Removing and re-adding the uikit framework in link binary with library, cleaning derived data and restarting xcode didn't work. I don't want to uninstall my xcode so I tried to copy codes of the class that I might have modified from other pc with xcode that works fine and paste it to mine. It worked!

Answer 3

Already tried all the solutions above. I still could not solve my problem. So I uninstall the Xcode and reinstall it. It worked magically.hope this helps.

Answer 4

Check the tool chains installed and select the right xcode tool chain. In my case i changed it from Swift 4.0 to xcode 9.2 and it worked.

Answer 5

Please don't make the same mistake like I did. In my case, I accidentally typed some words into Foundation framework file.

Answer 6

Cleaning Derived data worked for me
