Xcode(version 13.3.1) doesn’t support iOS 15.6

Question

I updated my iPhone to iOS 15.6 yesterday and I wanted to build in Xcode (version 13.3.1). But in Xcode it is showing 'iPhone (unsupported OS version)'. The Xcode release notes are not showing this version supports. https://xcodereleases.com

Answer 1

We can debug iOS(15.6) by using Xcode 13.4.1, which is not showing in release notes Xcode 13.4.1.

Answer 2

Alternative option which works for Xcode 13.2.1:

1. Close Xcode.
2. Download 15.5 from here https://github.com/filsv/iOSDeviceSupport/blob/master/15.5.zip
3. Unzip and rename it to 15.6
4. Move 15.6 folder to /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/
5. (Optional for WatchOS)- If you've Apple Watch paired with your iPhone download the latest watchOS version from here https://github.com/filsv/watchOSDeviceSupport and move file to /Applications/Xcode.app/Contents/Developer/Platforms/WatchOS.platform/DeviceSupport/

Answer 3

I had this error, in my case it was due to a paired Apple Watch. I solved it by deleting the device from Xcode and adding it again, while ensuring that the paired Apple Watch was unlocked and being worn (I had to tap the "Trust" button on the watch). This worked with iOS 15.6 on Xcode 13.4.1

Attempting to add the device while the watch was locked and on the dock would fail with this message. YMMV.

Answer 4

tested, iOS 15.6 phone is running Xcode 13.4.1

The iOS & iPadOS 15.5 SDK provides support to develop apps for iPhone, iPad, and iPod touch devices running iOS & iPadOS 15.6. The SDK comes bundled with Xcode 13.4.1, available from the Mac App Store. For information on the compatibility requirements for Xcode 13.4.1.

Same as @miletliyusuf, but just navigate to /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/ and duplicate the 15.5 folder and rename to 15.6, works instantly
