Your main issue will be keeping the build tools working with never versions of the OS.. Xamarin does not support IOS 18 nor the latest version of Xcode. you will need to fix the tools yourself, as you can no longer sign IOS 17 apps. IOS 19 is coming in the fall, and I expect early next year you will not be able to sign IOS 18 any longer. The story is similar with android.
both IOS and andriod are pretty caviler changing the build chain tools with each O/S release.
