Build error domain=com.apple.CoreSimulator.SimError, code=405

I can build on my iOS 15 emulator with no problems, but when building on my iOS 15 Device connected to xcode 13. I get the error:

error Failed to launch the app on simulator, An error was encountered processing the command (domain=com.apple.CoreSimulator.SimError, code=405): Unable to lookup in current state: Shutdown.

Any ideas?

Console:

I got this error when the simulator is already open while I ran react-native run-ios. Closed the simulator all the way. Reran the command and it worked.

Delete Xcode cache

Delete Project Build and indexes

Path:> about this Mac>Storage>Manage>Developer

Screen

To fix it, I simply select a specific iOS simulator and it runs successfully.

npx react-native run-ios --simulator="iPhone 8"

Just quit the Simulator, and then run again react-native run-ios.

do you run your code in an IDE? I faced the same problem today after updating XCode. If I run code in terminal I get other error: CompileSwiftSources normal x86_64 com.apple.xcode.tools.swift.compiler Try this

sudo xcrun simctl shutdown all && sudo xcrun simctl erase all

Please follow these steps:

Go to about this Mac -> Then Select Storage -> Select Manage -> Developer -> then Delete Project Build Data and Indexes.

It will work:

npx react-native run-ios --simulator="iPad Pro (9.7-inch)" 

attaching a screenshot for reference:

Make sure you have another simulator somewhere in the background, that was my problem after all.

Open xcode go to -> preferences -> Locations

and set Relative in Derived Data:
