Xcode 27 beta deployment issue

Thank you so much for the post. A little more information will be greatly appreciated. Like error messages in the Xcode terminal or setting up issue.

There is a great documentation how to set up physical devices with Xcode for deployment I would recommend:

https://developer.apple.com/documentation/xcode/running-your-app-on-simulated-or-physical-devices

Ensure Developer Mode is enabled on the iPhone. Go to Settings > Privacy & Security > Developer Mode. If it is toggled off, turn it on. The device will require a restart to apply the change.

Open Xcode and go to Window > Devices and Simulators. Find the iPhone 17 Pro in the left sidebar, right-click it, and select Unpair Device. Disconnect the iPhone, restart both the iPhone and Xcode, and reconnect the cable. Accept the "Trust This Computer" prompt on the device and enter the passcode.

If you are using "Automatically manage signing," try unchecking it, waiting a moment, and re-checking it to force Xcode to fetch the latest profiles. If you are using a Personal Team for signing, you may need to trust the certificate on the device.

If Xcode gives a specific error when the deployment fails, provide me that error. If it says "Failed to prepare device for development", this is usually a Developer Disk Image issue? If it says "App installation failed", it is typically a provisioning or bundle identifier mismatch. You can also open the Console app on your Mac, filter by the iPhone's name, and watch the logs during deployment to catch specific error as well.

Hope this helps, looking forward to see the error.
