  • Did you check [this identical question](https://stackoverflow.com/questions/54876861/which-version-of-xcode-support-ios-12-2?rq=1)? – Martin R May 28 '19 at 10:57
  • there is no support files for 16F203 into that list – srikanth kumar May 28 '19 at 11:00
  • unfortunately there is no 12.3.1 profile available yet. I've just downloaded latest profile and renamed it suitably 12.3.1 (16F203) for the time being, removed the app and it worked. Xcode ver 10.1. – Pavel Zaitsev May 29 '19 at 13:14

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

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

  • This worked for me. I had a (new stock) iPhone 7 running iOS 13.4, trying to use it with Xcode 11.3. – Womble Jul 20 '20 at 01:24

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.

You should update your XCode to support all listed devices.

For anyone who encounters this problem on Device with iOS 14 and Xcode 11.5 Version

_Download iOS 14.0 Zip from this link:

https://github.com/filsv/iPhoneOSDeviceSupport

_and past the folder to:

Xcode/Show Package Content/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport

_Quit and Restart both XCode and iPhone

_In XCode go to:

Window/Device and Simulator and Click on + Button Select your device Click Next and Click Done, and then build and run your XCode

Note: You can also clear your cache before the build and run your XCode

Hope this helps who faces this problem, cheers.
