The best place to go for info like this is Developer > Support > Articles > Xcode. As you can see in that table, building with the iOS 18 SDK and deploying on an iOS 18 device requires Xcode 16.

but I do not want to update my Xcode.

Keep in mind that that you can have multiple copies of Xcode installed. For example, on my Mac right now I have all of the following:

Xcode 15.0
Xcode 15.1
Xcode 15.2
Xcode 15.3
Xcode 15.4
Xcode 16.0
Xcode 16.1b5

[Excuse me while I go delete some of those!]

That’s very useful for limited testing. However, if your day-to-day work involves building an app and running it on your iPhone, then upgrading your iPhone to iOS 18 without first moving to Xcode 16 is going to be quite inconvenient.

What’s the problem with moving to Xcode 16?
