iOS simulator does not display anything

Question

I run the app as usual in Xcode 9.0.1 and Simulator 10.0 but the iOS simulator does not display anything. I have attached the image of the simulator below. I already tried to Erase all Content and Settings but it did not help. This is the first time that I've encountered something like this. Thank you.

Answer 1

This is quite a problem; it definitely looks like the simulator is corrupted. First, try a different simulator. You're using "iPhone 8 Plus - iOS 11.0" currently. Try a different one. They're all separate images. If that's the problem, you can delete that simulator and reinstall it. In Xcode:

• Window>Devices & Simulators

• Simulators

• Delete by right-clicking and selecting Delete. Install by pressing + at the bottom left.

If that doesn't address it, I would reinstall Xcode. This has to be corruption in either the simulator itself or one of the simulator images.

1. You can try clean your build and derived data.
2. If above won't work you can try quitting Xcode and Simulator and restart it again.
