[Bug]: onEnded on a gesture crashes client app

[victorbjorklund]

What happened?

This code:

<Rectangle
style={[
"fill(.red)",
"frame(width: 100, height: 100)",
"offset(x: gesture_state(:drag, .translation.width), y: gesture_state(:drag, .translation.height))",
"animation(.bouncy, value: gesture_state(:drag, .translation.width))",
"animation(.bouncy, value: gesture_state(:drag, .translation.height))",
"gesture(DragGesture().updating(:drag).onEnded(event("handle_swipe")))",
"frame(maxHeight: .infinity)"
]}
/>

Causes the client app to crash on simulator and iPhone. LVN Go works though so seems related to client library.

Library Version

0.4.0

Xcode Version

16.2

Swift Version

6.0.3

On which device or simulator are you running into the problem?

iPhone

Target Device Operating System Version

18.2

Relevant log output

Thread 1: Fatal error: No ObservableObject of type Observer found. A View.environmentObject(_:) for Observer may be missing as an ancestor of this view.

In observedelement.swift:

public var wrappedValue: ElementNode {
    overrideElement ?? observer.resolvedElement
  }

I spoke with Victor in Slack. This is working in 0.3.1 LVN Go but not in 0.4.0-rc.0 in Xcode
