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)

I updated to iOS 14 beta 6, and I have the same "Failed to start remote service" error on Xcode 11.6.

My workaround is as such: I keep both Xcode and Xcode-beta open, I run (Cmd+R) on Xcode 11.6 until it fails. Then, I run without building (Cmd+Ctrl+R) on Xcode-beta. That way, I keep using iOS 14 beta and Xcode 11.6 for work without updating the project to the iOS 14 SDK.

This actually works! Thank you @silver777, you saved my day

A legend! Thank you !

Thank you, works like a charm!

I got past all this and at the end of installation I’m getting: Unable to install KiteApp without any errors and app doesn’t get installed on my phone. I’m using Xcode 12.4 and running on iOS 15 beta device. Any suggestions?

for Released Xcode 13's support file and iOS 15 (not beta) , it can be built but shows: "Unable to install 'app name'"
Please advise

I have same issue. I cant deploy my app to my IOS 15 device. What should I do?

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

Finally I've installed my app on my device, but I had little difficulty while finding the Other Code Signing Flags.
Don't forget to click on the All option that below Build Settings

Hi, Could anyone share ios 15 simulator package for Xcode12.4?
Is it possible to run ios15 in xcode 12.4?

Quick response would be helpful and really appreciated.

I don’t believe you can create a link for that but if you launch Xcode 13 and open the simulator you want, then launch Xcode 12 the simulator should show up as run destination.

Despite trying this for my release version

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.
