View introspection gives zero height on Xcode 26 for any iOS version on v26.0.0 release

[gabriele-dechit]

Description

Introspecting any view with the .view IntrospectableViewType returns zero height on Xcode 26 with any iOS version when using v26.0.0 release.
By using Xcode 16.4 instead it returns a valid value.

.introspect(.view, on: .iOS(.v13, .v14, .v15, .v16, .v17, .v18, .v26)) { view in
    debugPrint("HEIGHT: \(view.bounds.height)") // <-- here I got 0 on Xcode 26
}

Expected behavior

It should return a non zero value.

.introspect(.view, on: .iOS(.v13, .v14, .v15, .v16, .v17, .v18, .v26)) { view in
    debugPrint("HEIGHT: \(view.bounds.height)") // <-- here I should get a positive value
}

Actual behavior

On Xcode 26 I get zero for view height, while on Xcode 16.4 I get a valid non zero value

.introspect(.view, on: .iOS(.v13, .v14, .v15, .v16, .v17, .v18, .v26)) { view in
    debugPrint("HEIGHT: \(view.bounds.height)") // <-- here I got 0 on Xcode 26 and a positive value on Xcode 16.4
}

Steps to reproduce

Attach this code to a SwiftUI view and run it with Xcode 26 by choosing any iOS simulator, it will return zero for the view height.

.introspect(.view, on: .iOS(.v13, .v14, .v15, .v16, .v17, .v18, .v26)) { view in
    debugPrint("HEIGHT: \(view.bounds.height)")
}

Re-run the same code with Xcode 16.4 by choosing any iOS simulator, it will return a positive non zero value for the view height

As documented:

prior to iOS 26, primitive views like Text, Image, Button, and layout stacks were drawn inside a subclass of UIView called _UIGraphicsView which was introspectable via .introspect(.view), however starting iOS 26 this is no longer the case and all SwiftUI primitives seem to somehow be drawn without an underlying UIView vessel.

So the .introspect(.view) is essentially no more useful on OS 26, is that correct?
Which is the better way to get the underlying element height now?

In my estimation, it's only useful in obtaining the underlying element of a UIViewRepresentable.
