This package seems right up my alley but might not be working with latest xcode (14 beta 1). Seems previews won't compile with this code in the file. And while the code will compile and run in the sim it does not seem to ever fill in the navbar title.

Here's the error from Preview:

LinkDylibError: Failed to build RecipeDetailView.swift

Hi!

I've just created a very simple test project (using the code snippet from this README), and found this worked still using Xcode 13.4.1 on iOS 15.5.

The same project required a change when running with Xcode 14 on iOS 16 – had to add the modifier .toolbar(.visible, in: .navigationBar) following after .matchedInlineTitle(in: namespace), but only because my test project had no other items in its toolbar, and iOS 16 release notes state that 'If a navigation bar has no title, toolbar items, or search content, it’s automatically hidden'.

I can't speak for the error, as I don't think testing against early developer betas of Xcode or iOS is particularly helpful given they're likely to be very buggy and not stable until much later in the year, closer to release. One of the Xcode projects I work on currently won't build at all due to a spurious Xcode 14 error, for which I've filed feedback with Apple.
