iOS Build Failed at compile time with issue “faile

问题:

I am getting following compile time issue when running the app with Xcode 10.3 beta 2 on iPad Air, I am getting the below issue.

Failed to find a suitable device for the type SimDeviceType : com.apple.dt.Xcode.IBSimDeviceType.iPad-2x with runtime SimRuntime : 10.3 (14E5239d) - com.apple.CoreSimulator.SimRuntime.iOS-10-3

Any help is greatly appreciated.

回答1:

It seemes like the old simulator process remained open in the background during an XCode update.

Simply running

sudo killall -9 com.apple.CoreSimulator.CoreSimulatorService

in terminal may solve the problem.
There shouldn't be a need for cleaning the project and/or build folder.

回答2:

If you quit Xcode and still get the same error, then try clean (command + shift + option + k) and select option "Clean" in popup. Repeat this 2 to 3 times. It works in my case.

回答3:

I was experiencing the same problem. In my case, I had launched the Simulator from a previous version of Xcode prior to building. The problem persisted when I quit the simulator, but restarting Xcode solved it for me.

回答4:

I just ran into the same issue on the latest Xcode 10.3 (10G8). Had to perform about 4 or 5 full project cleans, and bounce the box, before I could compile again. I wish Apple would get this fixed.

回答5:

I simply had to disconnect the iPad I had connected to my Mac. For some reason that was messing with the way Xcode was compiling.

回答6:

The only thing that solved it for me was the following:

1. Clear the ~/Library/Developer/CoreSimulator/Profiles/Runtimes folder
2. Restart Xcode
3. Clear the project
4. Run the project

回答7:

I solve this by launching the simulator first, Xcode will pass the build.

then run the project on the device.

hope this will help

If you are running multiple versions of xcode, you should check xcode-select -p to ensure you are using the correct version of xcode and compiler. If not, use xcode-select -s { correct xcode path } to set the correct version of xcode.

回答9:

Getting same issue but after an hour getting success to fix this issue there is xcode problem. So please reopen your xcode and then clean your project.. or use short cut command for clear (command + shift + option + k)

回答10:

If you are running app on the iPhone, then update your iPhone software version (If it is lower then 12.4)

Make sure that your iPhone software version should not be lower than 12.4.

It will work.
