Hi Albert, Thank you very much for your quick answer. I was running Xcode 26 RC1 but I just updated to the final release (17A324). My iPhone 14 Pro is running iOS 26 final (23A341) and I can also reproduce the issue on another iPad Pro device running iPadOS 26 final as well. I updated my bug report with a video that shows that, in my case, I usually obtain: --> isEditing: true --> isEditing: false --> isEditing: true when dragging the slider knob once (the two last events being received when releasing the knob). Thanks again for your help. Best regards.

Excellent news, the issue has been addressed in the iOS 17 beta 1 released yesterday. Thanks to everyone who made this important fix possible.

As written on a related thread, the issue has been fixed in iOS 17.2 beta 1.

The issue has not been fixed in the iOS 17 RC published today. I guess there might be troubles ahead for early adopters of the new Observation API (but not only, see my previous comment) when the owning view is presented in a modal.

This issue sadly generally affects instances of reference types stored as @State, even without using the new Observation API. It can therefore be considered an iOS 17 regression since storing simple reference types as @State without @ObservableObject was possible without leaks on iOS 16 (I can also confirm that the issue does not arise with @ObservableObject conformance). Though in general you likely want automatic observation, sometimes being able to store an instance of a non-observable reference type for the lifetime of a SwiftUI view is still useful and legitimate. This is for example how you might store an AVPlayer displaying its content in a VideoPlayer view, as show in this official code sample. I also reported this issue as FB13126425. Sample code is available here.
