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.

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.

Same issue but on an Intel MacBook Pro running macOS 12.6.

One would have hoped that today's Xcode 14 would support all of the versions of iOS and iPadOS also released today. Oh well. I guess we all need to wait for Xcode 14.0.1 or something. Can't wait to download yet another 7+GB Xcode release on my 10Mbps Internet connection.
baozzz OP

Yes, I found the same question.
nevillefromnords wharf OP

I am seeing the same thing as well, No issue on devices we updated to iOS 16 or devices still on iOS 15.6.1

I do have a directory for 15.7 in iOS deviceSupport though.

go figure....

same problem here, cant pari with 15.7 old iphone
stephenfromsyd OP

Same for me here. Does this mean if I archive the app and release to Apple it won't run on a device with iPAdOS 15.7 - the latest Version?
ghitai OP

I have same issue. XCode14.0(14A309) does NOT connect to iPadOS 15.7
SLboat OP

i found a temp way to fix this. after install xcode 14, download xcode 13.4.1.xip. keep two version xcode. the xcode 13.4.1 now seems can work with ios 16 and ios 15.7 same as good.

Yes, I found the same question.
daanodinot OP

sigh

I really don't understand how this can happen. Unless Apple plans to fix this very soon.
Maz_Kar OP

Exact same issue with Mac M1 Pro, MacOS: 12.6, Xcode: 14, iOS: 15.7
handmadeapps OP

Same thing here. It is quite amazing how Apple is utterly inconsiderate of small developers. It seems they've assumed that everyone is a big company with dozens of available devices at hand, at any time, with all iOS versions at the ready. Perhaps this is the same reason why Xcode is such a huge beast and that app uploads to the store often fail at low bandwidths. They probably also assume that everyone runs on a fiber optic line or is a Cupertino resident.

Waiting for Xcode 14 update. Hope it'll come soon because I need to test the app on a real device before uploading for customer.

Same issue with me.
Pimau OP

Works for me: Start Xcode 14. Start Xcode 13.4.1. to prepare the 15.7 device; wait until it is working. Close Xcode 13 AND 14, but keep the device connected to the computer. Now start Xcode 14 again, the device is functional.
theo_k OP

Same issue here. MacBook Pro M1 Max.
malariabob OP

Same here MacBook Pro m1 max
DaveHineman OP

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

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

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.
H Elzinga OP

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.
Silicon_Fox OP

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.
