Here's how to connect Apple TV 4K or Apple TV 4 to Xcode on a Mac with apps, apps, diagnostics, and other apps without sideloading.
If you think why you want to do this? Well, this is mainly because with Apple TV 4K, Apple has dropped the USB-C port, which means the only way to connect your Apple TV now with your Mac and Xcode is to do it wirelessly. Fortunately, Apple has introduced such functionality with Xcode 9 and later. This method will work with Apple TV 4 if you do not want to carry a USB-C cable. Here's how to set everything up.
Step 1. First things first, download the latest Xcode from Mac App Store then install on your Mac. Xcode is available from Apple on the Mac App Store for free. As mentioned earlier, it is important to note that Xcode 9 or later is required on macros 10.12.4 or higher so that all of these work well. Once you've set up all of this on your computer, follow the instructions from step 2 below.
Step 2. Update tvOS on Apple TV 4K to the latest version of tvOS 11 or later.
Step 3. On Apple TV, navigate to Settings> Remotes and Devices> Remote App and Devices and save your Apple TV on this screen.
Step 4. On a Mac, launch Xcode and navigate to Window> Devices and Simulators from the menu bar above.
Step 5. Now if both your Mac and Apple TV are nearby, following message should show up on Xcode’s Devices and Simulators window.
Step 6. Click the "Pair with your [Apple Apple TV]" button.
Step 7. The verification code will appear on the Apple TV screen, type Xcode to complete the pairing process between your Mac and Apple TV.
Now you should have your Mac show up on the Apple TV Remote App and Devices screen.
You should also have your Apple TV now appear in the Xcode Tool and Simulator window.
And that's it. Your Apple TV is now paired with Xcode on Mac, ready for app implementation, sideloading, and other diagnostics.
