There may be problems with running your app on latest XCode version, but you can add supported devices to your current XCode's folder.

1. download version of required iOS from https://github.com/filsv/iPhoneOSDeviceSupport
2. Put it to Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport inside of XCode folder
3. Restart XCode

Temporary solution for this change folder named 12.3.1.its working for me once we get 12.3.1 package content we will move corresponding place

Answer 4

I have the same problem , and here is the solution worked for me

You should make a folder named 12.3 (... what is written in your error message) in Program/Xcode-beta/Contents/Developer/Platforms/iPhoneOS.platforms/DeviceSupport/ and copy the files from 12.2 in there.

Close xcode completely and reopen it.

Now you can run your apps on iOS 12.3.

Answer 5

Your current version of Xcode does not support the iOS 12.3.1 version of the SDK.

There are a couple of options available:

1. Update Xcode to the latest version
2. Download a add the required device support files to your current version.

You can download the support files here or from the Apple Developer website. There is also instructions on where to place the files once downloaded

Answer 6

You should update your XCode to support all listed devices.
