@Claude31. I got the same problem (Xcode12)
ContentView.swift:
Code Block swift| import SwiftUI |
|
| struct ContentView: View { |
| @State var isSideBarPresented = true |
| @State var node = Node3D() |
|
| var body: some View { |
| VStack { |
| Button("Toggle") { isSideBarPresented.toggle() } |
| HSplitView { |
| Color.white.frame( |
| minWidth: 100, |
| maxWidth: .infinity, |
| minHeight: 0, |
| maxHeight: .infinity |
| ) |
|
| if isSideBarPresented { |
| Node3DConfigurationView(node: $node) |
| } |
| } |
| }.frame( |
| minWidth: 0, |
| maxWidth: .infinity, |
| minHeight: 0, |
| maxHeight: .infinity |
| ) |
| } |
| } |
Node3DConfigurationView.swift:
Code Block swift| import simd |
| import SwiftUI |
|
| struct Node3D { |
| var pivot: simd_float3 = .zero |
| var position: simd_float3 = .zero |
| var rotation: simd_float3 = .zero |
| var scale: simd_float3 = .zero |
| } |
|
| /* not sure if needed, but I randomly got some error without it */ |
| fileprivate func wrap(_ binding: Binding<Float>) -> Binding<NSNumber> { |
| Binding( |
| get: { NSNumber(value: binding.wrappedValue) }, |
| set: { binding.wrappedValue = $0.floatValue } |
| ) |
| } |
|
| struct Node3DConfigurationView: View { |
| @Binding var node: Node3D |
| var body: some View { |
| ScrollView(.vertical) { |
| Group { |
| makeSection("Pivot", value: $node.pivot) |
| makeSection("Position", value: $node.position) |
| makeSection("Rotation", value: $node.rotation) |
| makeSection("Scale", value: $node.scale) |
| } |
| .textFieldStyle(RoundedBorderTextFieldStyle()) |
| } |
| } |
| |
| func makeSection(_ headerTitle: String, value: Binding<simd_float3>) -> some View { |
| Section(header: makeHeader(headerTitle)) { |
| HStack { |
| HStack { |
| Text("x") |
| TextField("\(headerTitle)X", value: wrap(value.x), formatter: NumberFormatter()) |
| } |
| .frame(minWidth: 50) |
| HStack { |
| Text("y") |
| TextField("\(headerTitle)Y", value: wrap(value.y), formatter: NumberFormatter()) |
| } |
| .frame(minWidth: 50) |
| HStack { |
| Text("z") |
| TextField("\(headerTitle)Z", value: wrap(value.z), formatter: NumberFormatter()) |
| } |
| .frame(minWidth: 50) |
| }.padding() |
| } |
| } |
|
| func makeHeader(_ title: String) -> some View { |
| Text(title).frame(maxWidth: .infinity, alignment: .leading) |
| } |
| } |
AppDelegate.swift (Default, generated by Xcode):
Code Block swift| import Cocoa |
| import SwiftUI |
|
| @NSApplicationMain |
| class AppDelegate: NSObject, NSApplicationDelegate { |
| var window: NSWindow! |
|
| func applicationDidFinishLaunching(_ aNotification: Notification) { |
| let contentView = ContentView() |
| window = NSWindow( |
| contentRect: NSRect(x: 0, y: 0, width: 480, height: 300), |
| styleMask: [.titled, .closable, .miniaturizable, .resizable, .fullSizeContentView], |
| backing: .buffered, defer: false |
| ) |
| window.isReleasedWhenClosed = false |
| window.center() |
| window.setFrameAutosaveName("Main Window") |
| window.contentView = NSHostingView(rootView: contentView) |
| window.makeKeyAndOrderFront(nil) |
| } |
| } |
