Answer 3

I have the same problem when I updated the launch screen in the project.

I just do the following things that the problem cleared.

1. Install a backup of the source code.

2. Delete the file LaunchScreen.storyboard.

3.Pop up will appear, and he will ask you to save the storyboard file again or close the parameter, click the close button.

4. Just add the LaunchScreen.storyboard file to your current project from the source code.

5. Now clean, then complete the assembly, the problem will be cleared.

All this does not work for me or for you ????

Waring: you can do it

The reason is that you are loading Simulators on a new Xcode, you must delete it! path "/ Library / Developer / CoreSimulator / Profiles / Runtimes"

For example, your version of xcode is Xcode 8.0, now you download Xcode 9.0, you have two xcode, you download ios 10 Simulator to Xcode 9.0, then Xcode 8.0 will appear that the storyboard cannot be started because Xcode 8.0 is the default Simulator - ios 10, Conflicted !!!
