Xcode 26.4.1, iOS 26.4.2, watchOS 26.4, Apple Watch Ultra 3 not appearing as development device.

Thanks for the post, there are many Apple Watch engineers that I’m just they’ll jump into the thread, however this question seems like how to start with Apple Watch development and pair the Apple Watch to Xcode. When an Apple Watch fails to appear as a development device in Xcode, the issue usually stems from the wireless pairing bridge between Xcode, the iPhone, and the Watch, or a missing Developer Mode toggle.

On the iPhone go to Settings → Privacy & Security → Developer Mode and toggle it on. On the Apple Watch go to Settings → Privacy & Security → Developer Mode and toggle it on. Both devices will require a restart. Connect the paired iPhone to your Mac via a physical cable. In Xcode, go to Window → Devices and Simulators. Select your iPhone in the left sidebar. Look at the Paired Watches section. If the Watch is listed but has a yellow warning triangle, hover over it. It may say Preparing device for development.

If you have successfully completed all the steps, you should be able to proceed. However, if you encounter any issues, please inform the developers here about the specific problem you are experiencing on the iPhone. Additionally, please indicate whether the device is paired with an Apple Watch or not, and whether Xcode is recognizing the device.

My Iwatch doesn't have Settings → Privacy & Security → Developer Mode.

How do I have developer mode show?
