iOS 17.x , Xcode and Xojo

My Xcode isnt offering any updates, and has iOS 16 libraries
Some iPad customers are reporting problems with an app I have in the app store, which is always a pain as I have precious few ways to find out what might be going wrong.
But I cannot simulate iOS 17.

My Mac is on Monterey… is that the issue?

(I’m always reluctant to upgrade the OS because it usually means I cannot build anything for at least a week while I work out what has to be fixed ‘this time’)

You need macOS 13 at minimum OS for Xcode 15 and iOS 17 simulator
