Xcode – 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:

success Successfully built the app

    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)"

    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.

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

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

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

    Solutions:

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

    2. If, during the build, you get e.g. info Launching iPhone 13 (iOS 15.5) but the simulator does not open, do the following: Before the build is finished, right-click the simulator icon and go to Device and choose the device the build says it is going to build it on.

    Very weird behavior in my opinion, but I tried everything and I finally found the solution.

    The problem was due to me changing my email address of my apple id.
    Seems like the Simulator tries to use the apple id internally and thus – if it cannot connect – does not boot correctly.

    After fixing the email address in XCode -> Preferences -> Accounts (i just added the new email address and removed the old one) everything works again.

    This instantly fixed the error for me:

    1. Quit the simulator
    2. Go to About this Mac > Storage > Manage > Developer
    3. Delete XCode Cache
    4. Re-run npx create-react-app run-ios

    I saw the dot near the simulator (meaning it was active) but it did not open.
    What helped me was doing:
    Right click the simulator –> Device –> choose one.
    that opened it.
