Xcode 14 failed to prepare iOS 15.7 device?

An update to Xcode 14 appeared in the Mac App store today 2022-11-12. After updating Xcode from the App store app on my M1 MacBook, and plugging in an iPad, also updated today 2022-11-12 to iOS 15.7, Xcode says: "Failed to prepare the device for development".

A restart of both the Mac and the iPad doesn't fix this issue. Is there a way to get Xcode 14 to debug an 15.7 iPad? Or is a different build required?

There also is no 15.7 directory inside Xcode's iPhoneOS DeviceSupport directory.

Same issue here. MacBook Pro M1 Max.

Same here MacBook Pro m1 max

I'm stuck, too. None of the IOS devices will talk to my M1 Mac

Ooh! Just noticed that there is an update available for Mac, installing now.

This is absolutely horrible. First, the iPad pestered me about the update, so I updated to iPad OS 15.7, it stopped working with Xcode 13... So I spent 3 hours installing Xcode 14 because 'not enough disk space', but I still cannot do any development as my iPad 'is not prepared'. Is there even any communications team at apple to tell us devs what's goin on, what can be done about it and if there's any timeline for the fix?

Same issue Mac Studio & M1 MacBook Pro with iphone 13 pro and 11 inch iPad Pro

We are aware of the issue. The Xcode 14 Release notes are updated with a workaround:

Xcode 14 cannot be used with iOS 15.7 for development. (99847608) Workaround: Use Xcode 13.4.1 with iOS 15.7.

After some experimenting and the suggestions above, I downloaded the Xcode 13.4.1 version, and started it. Next open the devices overview, and wait for the device to be "ready". This initializes the iOS 15.7 version for development I guess.

Next I could use Xcode 14, for development and testing on the device. Even without Xcode 13.4.1 running. (I haven't tried if this still works after a reboot)

Working development environment:

  • macOS 12.5
  • Xcode 13.4.1
  • (iPhone 7) iOS 15.6

Yesterday (2022-09-13) updated to:

  • macOS 12.6
  • Xcode 14.0
  • (iPhone 7) iOS 15.7

Result: Xcode 14.0 says about iPhone it "failed to prepare device for the deployment".

Downloaded Xcode 13.4.1 xip package, unpacked it (xip -x), copied to /Applications. Started Xcode 13.4.1, it immediately was able to work with my iPhone 15.7. Deployed project to it. Quit Xcode 13.4.1, opened Xcode 14.0, now it was able to work with the iPhone.

Encountering same issue while testing iPad error handling. Unfortunately updating to 15.7 broke testing as well as iPad Pro model MM172CL/A "Airplane Mode" in settings no longer works since I need to use that feature in my tests as well.

Fix: cd /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport sudo ln -s 15.5 15.7

Explanation: Xcode 13.4.1 contains DeviceSupport folders up to 15.5 and works with iOS 15.7 devices. 15.7 is missing in 14.0, it will try to use 15.6, which fails to prepare the iOS device for development. If we copy 15.5 to 15.7 or create a link, the 15.5 folder is used, which works for iOS 15.7. My iPhone 7 Plus is recognised instantly over the network, and Developer menu appears in Settings.

Not sure why, but after upgrading to macOS 12.6, now I can deploy the app to iPad with iOS 15.7 by Xcode 14 which does not support iOS 15.7 (previously it's impossible with old macOS version 12.5) 😅

Xcode 14.0 (14A309) is not having iOS 15.7 Device support sdk. Therefore unable to run on these devices. To Solve this problem, there is two option.

  1. downgrade or degrade iOS into the Device.
  2. Add the device support iOS sdk into the Xcode 14.

Xcode 14.0.1 Release Candidate is now available for download, addressing this issue. If you continue to see issues using Xcode 14.0.1 with iOS 15.7, please let us know through Feedback Assistant, and post the FB numbers here.

LMFAO another 7gb download literally is so crazy and annoying every time ☠️💀
