xcode - iOS simulator is not launching

Question

I am facing this problem again and again. Anybody can give the solution to this problem except reboot the Mac?

I have already tried these tricks

1. simulator-->services-->a reset content and settings,
   closing xcode and re-opening
   xcode --> developer toos --> simulator -->(open the simulator),
   quit simulator Activity monitor -->(the simulator is closed so nothing here to force close)

First of all quit your simulator.
And then quit and restart Xcode.
And then run your project.

3. Restart xcode and the simulator

Answer 1

I also have this issue and googled this, which redirect to this question. Mine was xcode10 What i have done is as follows

1. Quit the simulator & Xcode.
2. Opened Activity monitor, selected cpu option and search for sim, killing all the process shown as result.
3. Then fired up the terminal and run sudo xcrun simctl erase all. It will delete all content of all simulators. By content if you logged in somewhere password will be gone, all developer apps installed in that simulator will be gone.

Doing these resolved my issue. Hope it helps.
