How to run on iOS 17 Device using Xcode 14 – Ios

The Problem:

Xcode 14 does not support running apps on iOS 17 devices out of the box. How can we enable iOS 17 device support in Xcode 14 to build and run apps on actual iOS 17 devices?

The Solutions:

Solution 1: Enable Core Device Support

In the Terminal, enter the following command:

defaults write com.apple.dt.Xcode DVTEnableCoreDevice enabled

Restart Xcode 14, and the iOS 17 device will appear in the list of devices. You can now run and debug your app on the device.

Note: You may need to go to the Devices and Simulators window to pair and trust the device.

Solution 2: Running on iOS 17 Device via Xcode 14

To run your app built with Xcode 14 on an iOS 17 device, follow these steps:

1. Archive the App: Archive the app in Xcode 14 using the "Any iOS Device" destination.
2. Show Archive in Finder: In Xcode 14’s Organizer, select the archive and click "Show in Finder."
3. Extract the App: Extract the app from the archive. It will be located in "Products -> Applications."
4. Close Xcode 14 and Open Xcode 15: Quit Xcode 14 and launch Xcode 15.
5. Install the App via Xcode 15: In Xcode 15, select your iOS 17 device in "Devices and Simulators." Click the "+" button under "Installed Apps" and drag the app file from step 3 onto it.
6. Run the App: Manually launch the app on your iOS 17 device. Do not run it from Xcode 15, as this will replace the installed app.
7. Attach to Process for Debugging: In Xcode 15, attach to the app’s process via "Debug -> Attach to Process." Breakpoints may not work, but you can still print to the log for debugging purposes.

Alternatively, you can deliver the app via TestFlight instead of steps 1-6. Then, attach to the app’s process using Xcode 15 and your iOS 17 device.

Solution 3: Deploying iOS 17 Devices on Xcode 14

To run iOS 17 devices on Xcode 14, follow these steps:

1. Enable CoreDevice by executing the command: defaults write com.apple.dt.Xcode DVTEnableCoreDevice enabled in Terminal.
2. Restart Xcode.
3. If deployment errors persist, install Xcode 15.

Explanation:

By enabling CoreDevice, you allow Xcode 14 to communicate with the latest devices that Xcode 15 supports. However, for optimal functionality and to avoid deployment errors, it is recommended to install Xcode 15. This installation includes the necessary device support files.

Solution 4: Use Xcode 15 Beta

Currently, there are no device support files available for iOS 17 in Xcode 14. This is because iOS 17 devices use a new device stack (CoreDevice) that allows for interoperability with all versions of Xcode on the system. This means that updating the device stack through newer Xcode versions will resolve the issue.

To run iOS 17 devices on Xcode 14, Apple recommends using Xcode 15 beta. This will automatically install the necessary updates to support future versions of iOS, eliminating the need for manual device support file installation. This approach provides a more streamlined and supported way to run iOS 17 devices in Xcode.

Solution 5: Command Terminal Manipulation

To run on an iOS 17 device using Xcode 14, follow these steps:

1. Close Xcode if it’s running.

2. Open a Terminal window.

3. Run the following two commands in the terminal:

   defaults write com.apple.dt.Xcode DVTEnableCoreDevice disbled
   

   defaults write com.apple.dt.Xcode DVTEnableCoreDevice enabled
   

4. Reopen Xcode and connect your iOS 17 device. You should now be able to run your app on the device.
