I am using relative positioning inside a NavigationView. The issue about the wrong position and enter animation makes this library unusable. If there is no NavigationView, there is no issue. But I do need it.

enum BottomSheetPosition: CGFloat, CaseIterable {
    case top = 0.83
    case middle = 0.385
}

@State var bottomSheetPosition: BottomSheetPosition = .middle

BottomSheetView(
                position: $bottomSheetPosition,
                header: {
                },
                content: {
                    ForecastView(bottomSheetTranslationProrated: bottomSheetTranslationProrated)
                    
                }
            )
            .onBottomSheetDrag { translation in
                bottomSheetTranslation = translation

                withAnimation(.easeInOut) {
                    if bottomSheetPosition == BottomSheetPosition.top {
                        hasDragged = true
                    } else {
                        hasDragged = false
                    }
                }
            }

Hey. Thanx for such awesome lib)

To reproduce: In sample app drag sheet to top position, the drag content even higher. Then drag header to any other position without touching content. After that try to drag content.

• [x] Safely unwrap the actual position after dragging. Can be nil which causes a hard crash
• [x] When state changes make the UI reflect those changes by using updateUIViewController
• [x] Move modulate function into the ondrag modifier so value is always between 0 and 1 instead of the raw numbers.
• [ ] Find vertical scrollview based on tag to prevent crashes on multiple nested scrollviews.
• [x] Include manual disable and enable drag functionality.
• [x] Add the ability to exclude values from the snapping enum
• [x] Improve position callbacks to better handle certain scroll cases.

Working on a new interface for bottom sheet. Will be renamed to bottom sheet plus, and follow a similar pattern to what Apple implemented in iOS 16, but with iOS 14+ support.

Will allow for:

• [x] Combining fixed heights, fractions and predefined heights
• [x] Interchangeable with the iOS 16 API
• [x] Having a height callback on your sheet presentation for custom interactions
• [x] Support for a sticky header

    @State var selectedDetent: BottomSheet.PresentationDetent = .large
