问题
My phone has updated to iOS 12.3 beta, the latest Xcode 10.2 beta only supports up to iOS 12.2.
Is there a beta version of xcode anywhere that is compatible with iOS 12.3?
I guess the options are to wait for apple to release a new version of xcode or to roll back. unless anyone knows otherwise?

I find a solution to fix this problem.
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.
Now you can run your apps on iPhones with iOS 12.3.

Any update on The IOS 12.3 Beta Developer Disk Image?
The official Debugging File for iOS 12.3 is not available.
You can try the following method to let Xcode support debugging iOS 12.3 devices.
1. Go to the folder /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
2. Create a folder named "12.3".
3. Copy the "12.2" file to the "12.3" folder.

How I fixed a similar issue with iOS 12.4
Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport and create folder called 12.4 (16G77) and copy the files from one of the previous folders f.e 12.3
Go to Xcode and click on the "Set active scheme menu" and click on Download Simulators at the bottom:
Xcode will automatically start updating and re-creating the supporting files for 12.4:
Hope this will help someone.

Actually, Xcode 10.2.1 could debug with real devices running iOS 12.3
Try it by yourself.
