Unable to boot the simulator, launchd failed to respond Xcode

I downloaded Xcode 10.1 from AppStore but it had some errors at startup and couldn't show up. So I downgraded Xcode to version 10.0 (10A255) from Apple official downloads. IDE works fine but now I can't start simulator. I've tried every possible solution on the internet for hours. Here is the logs:

CoreSimulatorService[393] : com.apple.CoreSimulator.CoreSimulatorService 581.2 starting.

What can I do?

For my Xcode 15.3 and Sonoma 14.4 helped the removing of simulator's Caches folder at ~/Library/Developer/CoreSimulator

  1. Open Finder.
  2. Execute ⌘ Cmd + ↑ Shift + G (go to folder).
  3. Execute ⌘ Cmd + V (pastes copied text) of copied ~/Library/Developer/CoreSimulator path.
  4. Remove Caches folder.

P.S. If not helped than try to remove DerivedData of your project at ~/Library/Developer/Xcode/DerivedData

Goto System Setting => General => Storage => 'Storage Settings' => Developer (i) icon. Delete Xcode Caches. Then try again! enter image description here

Xcode > File > Workspace Settings > click on Derived Data > clear Derived Data and clear the CoreSimulator caches. That works for me.

For me this happened and was gone after I restarted the mac but after sometime it came back again, some people are telling to restart but for me it came back again so i don't think so that is a permanent solution. So currently what solved it immediately was what's mentioned in the first answer i.e deleting the Xcode Cache by:

clicking on apple logo -> System Settings -> Search Storage Settings -> click on more info "i" icon of Developer button -> Select xcode cache and delete -> restart xcode and then run. Thank you!

ps: I am using Apple M1 Pro with Sonoma 14.0 macOS and Xcode 15.0.1

In Xcode 14.2 cleaning the build folder resolved this issue for me.

 Product -> Clean Build Folder

  1. Right-click on the simulator icon
  2. Click on "Options".
  3. Click on "Show in Finder"

When the finder is open

  1. Right-click on the icon again
  2. Then click "Move to bin"

After deleting the simulator

  1. Go to your computer bin and restore it

It must work.

You're welcome

Hmm, sad to say but restarting my Mac actually fixed the issue.

In my case clearing derived data helped. You can do it like this:

Open Xcode -> Preferences -> Locations -> Derived Data (Click the little arrow) -> Delete the folder.

In my case

Unable to boot the Simulator.

Code: 60
Failure Reason: launchd failed to respond.

Was fixed by restarting my wifi router which was playing up.
