Using iOS 15 devices with Xcode 12.5 (instead of Xcode 13)

ios-xcode-device-support.sh

# The trick is to link the DeviceSupport folder from the beta to the stable version.
# sudo needed if you run the Mac App Store version. Always download the dmg instead... you'll thank me later :)

# Support iOS 15 devices (Xcode 13.0) with Xcode 12.5:
sudo ln -s /Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/15.0 /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport

# Then restart Xcode and reconnect your devices. You will need to do that for every beta of future iOS versions

# (A similar approach works for older versions too, just change the version number after DeviceSupport)

Despite trying this for my release version

I found the solution. It's about signing. To my rough understanding, now Apple changed the way of signing.

In project:

TARGETS>Building Setting>

Find /search

"OTHER_CODE_SIGN_FLAGS" Add the following flag to Debug mode(or Release mode depending on your purpose)

--generate-entitlement-der

We still are unable to install the ipa on iOS 14.7, iOS 15. Any ideas ?

If you need iOS 15.1 support (Xcode 13.1 has only 15.0 directory) you can also do this as a follow up to the original gist:

sudo ln -s 15.0 /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/15.1

which works at the time of writing (Xcode 13.1 and Xcode 12.5.1).

If you need iOS 16 support on Xcode 13.4.1, here's the command (make sure you've Developer Mode enabled):

sudo ln -s /Applications/Xcode\ 14\ Beta.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/16.0 /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport

I saw something in a build log (from Xcode 14) about CoreDevice being disabled, took a guess and if you do:

defaults write com.apple.dt.Xcode DVTEnableCoreDevice enabled

Then restart Xcode the iOS 17 device will show up in Xcode like this. Then you can run and debug the app as usual. I have Xcode 15 installed alongside Xcode 14 but not sure if thats a requirement. It took a while to copy symbols from device but eventually it got there.
