Xcode 9 simulator does not work after installing xcode 10 beta

Question

I had Xcode 9.4.1 installed. I also installed Xcode 10 beta 6. Now the simulator no longer works correctly, it opens up but does not display anything. Precisely before it only displayed a black screen, then a colored screen (here is the screenshot).

I have tried many solutions proposed here on StackOverflow but it did not solve the problem.

Below is what i did actually:

• run defaults write com.apple.CoreSimulator.IndigoFramebufferServices FramebufferRendererHint 3
• Restart mac
• Delete and reinstall XCode 9.4.1
• Delete XCode 10 beta 6
• Erase all content and settings on simulator
• Delete simulators on XCode and readd

Any help regarding the issue will be highly appreciated.

Thanks.

Answer 1

It happened for me once I have run Xcode 9.4 project on Xcode 10. It seems that the project has taken Xcode 10 preferences and once I get back to run the project on Xcode 9.4 conflicts happen between Xcode versions settings.

SOLUTION:

For me I closed both Xcode Versions, then restart my mac. Then everything is well and I'm able to run projects on simulators again for both versions of Xcode.
