iOS模拟器连接超时

Question

When I try to simulate my iOS app using Xcode version 9.4 simulator, it keeps on loading and loading till it sends me the following message:

Failed to initiate service connection to simulator. Connection timed out

My Internet is fast and I have updated my macOS HighSeirra 10.13.4 in no time.

Answer 1

Close Xcode Properly (from your dock as well )

Close simulator

And Restart Xcode and Simulator.

Let it build & index the project

And it should work fine after that..

Thanks

Happy Coding ;)

PS Clear Derived Data , if above steps didn't work for you.

Answer 2

Close Simulator.

Try Clean your project and Run again.

If it does not help try restart XCode

Is it does not help try reboot your Mac

PS Please check if you have only one running copy of simulator
