My iPhone xs won’t show iOS 17 update

what happens when you try to update? Any error message? Go to settings - general - software update and see what it says there.

What does it say in Settings>General>About>Model Number?

"My iPhone xs won’t show iOS 17 update: I need iOS 17 on my XS iPhone to be able to pair with my Apple 9 watch. My only Xs update shows iOS 16.6.1 and I have 200 GB left in my storage. How can I download 17?"

Try Updating Using a Computer:

• Have a Computer Handy? If so, try using a computer to update. Use my User Tip Update your iPhone Using a Computer - User Tip. If any updates are available, they will install, sure enough.
• Use of Ethernet: If WiFi is not working, you can try connecting your computer using Ethernet. If you have no ethernet adapter on your Mac, then this is the adapter to use: The Belkin USB-C to Gigabit Ethernet Adapter - Apple

IMPORTANT: If you have an option to update, however, then be certain you backup your iPhone first. That way, you will have something to restore your iPhone from should anything go wrong with the update
