I am new to SwiftUI, and I wrote a ReorderableForEach struct with onDrag and onDrop, which is working well on iOS17. However it's not wokring on iOS18 beta1 or beta2 on my iPhone or simulator. When I long press the item, nothing happens. When I remove onDrop, I can perform a Drag animation, so I think something wrong with my onDrop code. the whole code: import UIKit import SwiftUI public typealias Reorderable = Identifiable & Equatable struct GridData: Identifiable, Equatable { let id: Int } public struct ReorderableForEach<Item: Reorderable, Content: View, Preview: View>: View { @Binding private var active: Item? @State private var hasChangedLocation = false private let items: [Item] private let content: (Item) -> Content private let preview: ((Item) -> Preview)? private let moveAction: (IndexSet, Int) -> Void private var onDropAction: ((Item) -> Void)? private var allowReorder: Bool public init( _ items: [Item], active: Binding<Item?>, allowReorder: Bool, @ViewBuilder content: @escaping (Item) -> Content, @ViewBuilder preview: @escaping (Item) -> Preview, moveAction: @escaping (IndexSet, Int) -> Void, onDropAction: ((Item) -> Void)? = nil ) { self.items = items self._active = active self.allowReorder = allowReorder self.content = content self.preview = preview self.moveAction = moveAction self.onDropAction = onDropAction } public init( _ items: [Item], active: Binding<Item?>, allowReorder: Bool, @ViewBuilder content: @escaping (Item) -> Content, moveAction: @escaping (IndexSet, Int) -> Void, onDropAction: ((Item) -> Void)? = nil ) where Preview == EmptyView { self.items = items self._active = active self.allowReorder = allowReorder self.content = content self.preview = nil self.moveAction = moveAction self.onDropAction = onDropAction } public var body: some View { ForEach(items) { item in if !allowReorder { contentView(for: item) } else if let preview { contentView(for: item) .onDrag { return dragData(for: item) } preview: { preview(item) } } else { contentView(for: item) .onDrag { return dragData(for: item) } } } } private func contentView(for item: Item) -> some View { content(item) .opacity(active == item && hasChangedLocation ? 0.5 : 1) .onDrop( of: [.text], delegate: ReorderableDragRelocateDelegate( item: item, items: items, active: $active, hasChangedLocation: $hasChangedLocation ) { from, to in withAnimation { moveAction(from, to) } } onDropAction: { item in onDropAction?(item) } ) } private func dragData(for item: Item) -> NSItemProvider { active = item return NSItemProvider(object: "\(item.id)" as NSString) } } struct ReorderableDragRelocateDelegate<Item: Reorderable>: DropDelegate { let item: Item var items: [Item] @Binding var active: Item? @Binding var hasChangedLocation: Bool var moveAction: (IndexSet, Int) -> Void var onDropAction: ((Item) -> Void)? func dropEntered(info: DropInfo) { guard item != active, let current = active else { return } guard let from = items.firstIndex(of: current) else { return } guard let to = items.firstIndex(of: item) else { return } hasChangedLocation = true if items[to] != current { moveAction(IndexSet(integer: from), to > from ? to + 1 : to) } } func dropUpdated(info: DropInfo) -> DropProposal? { DropProposal(operation: .move) } func performDrop(info: DropInfo) -> Bool { hasChangedLocation = false active = nil onDropAction?(item) return true } } struct ReorderableDropOutsideDelegate<Item: Reorderable>: DropDelegate { @Binding var active: Item? func dropUpdated(info: DropInfo) -> DropProposal? { DropProposal(operation: .move) } func performDrop(info: DropInfo) -> Bool { active = nil return true } } public extension View { func reorderableForEachContainer<Item: Reorderable>( active: Binding<Item?> ) -> some View { onDrop(of: [.text], delegate: ReorderableDropOutsideDelegate(active: active)) } } #Preview { ReorderableForEach( (1...10).map { GridData(id: $0) }, active: .constant(nil), allowReorder: true ) { item in Text("Item \(item.id)") .padding() .background(Color.blue) .cornerRadius(8) } preview: { item in Text("Preview \(item.id)") .padding() .background(Color.red) .cornerRadius(8) } moveAction: { from, to in print("Move from \(from) to \(to)") } } Am I missing something or this is a bug on iOS18? Thanks in advance.
