Issue #638 Use commandDefinitions in XCSourceEditorExtension. import Foundation import XcodeKit class SourceEditorExtension: NSObject, XCSourceEditorExtension { func extensionDidFinishLaunching() { } var commandDefinitions: [[XCSourceEditorCommandDefinitionKey: Any]] { func makeDef( _ className: String, _ commandName: String ) -> [XCSourceEditorCommandDefinitionKey: Any] { guard let bundleId = Bundle(for: type(of: self)).bundleIdentifier else { return [:] } return [ XCSourceEditorCommandDefinitionKey.identifierKey: bundleId + className, XCSourceEditorCommandDefinitionKey.classNameKey: className, XCSourceEditorCommandDefinitionKey.nameKey: commandName ] } return [ makeDef(TypeCommand.className(), "Type"), makeDef(ReloadCommand.className(), "Reload"), ] } } There is a weird crash that we can’t seem to declare functions or use commandDefinitions, the workaround is to declare in plist...

Issue #636 Normally we can just wrap NSTextField struct SearchTextField: NSViewRepresentable { @Binding var text: String var hint: String var onCommit: (String) -> Void func makeNSView(context: NSViewRepresentableContext<SearchTextField>) -> NSTextField { let tf = NSTextField() tf.focusRingType = .none tf.isBordered = false tf.isEditable = true tf.isSelectable = true tf.drawsBackground = false tf.delegate = context.coordinator tf.font = NSFont(name: OpenSans.bold.rawValue, size: 14) tf.placeholderString = hint return tf } func updateNSView( _ nsView: NSTextField, context: NSViewRepresentableContext<SearchTextField> ) { nsView....

Issue #633 Use autoclosure and AnyView @available(iOS 13.0, OSX 10.15, tvOS 13.0, watchOS 6.0, *) public extension View { func applyIf<T: View>(_ condition: @autoclosure () -> Bool, apply: (Self) -> T) -> AnyView { if condition() { return apply(self).erase() } else { return self.erase() } } } Button(action: onSearch) { Image("search") .resizable() .styleButton() .overlay(ToolTip("Search")) } .buttonStyle(BorderlessButtonStyle()) .applyIf(showsSearch, apply: { $0.foregroundColor(Color.orange) })

Issue #632 Use Group private func makeHeader() -> some View { Group { if showsSearch { SearchView( onSearch: onSearch ) .transition(.move(edge: .leading)) } else { InputView( onAdd: onAdd ) .transition(.move(edge: .leading)) } } } withAnimation { self.showsSearch.toggle() }

Issue #630 For SwiftUI app using NSPopover, to show context popover menu, we can ask for windows array, get the _NSPopoverWindow and calculate the position. Note that origin of macOS screen is bottom left (lldb) po NSApp.windows ▿ 2 elements - 0 : <NSStatusBarWindow: 0x101a02700> - 1 : <_NSPopoverWindow: 0x101c01060> let handler = MenuHandler() handler.add(title: "About", action: onAbout) handler.add(title: "Quit", action: onQuit) guard let window = NSApp.windows.last else { return } let position = CGPoint( x: window....

Issue #629 Use Picker with SegmentedPickerStyle. Picker(selection: $preferenceManager.preference.display, label: EmptyView()) { Image("grid") .resizable() .padding() .tag(0) Image("list") .resizable() .tag(1) }.pickerStyle(SegmentedPickerStyle()) .frame(width: 50) .padding(.leading, 16) .padding(.trailing, 24) Alternatively, we can make custom NSSegmentedControl import AppKit import SwiftUI struct MySegmentControl: NSViewRepresentable { func makeCoordinator() -> MySegmentControl.Coordinator { Coordinator(parent: self) } func makeNSView(context: NSViewRepresentableContext<MySegmentControl>) -> NSSegmentedControl { let control = NSSegmentedControl( images: [ NSImage(named: NSImage.Name("grid"))!, NSImage(named: NSImage.Name("list"))! ], trackingMode: .selectOne, target: context.coordinator, action: #selector(Coordinator.onChange(_:)) ) return control } func updateNSView(_ nsView: NSSegmentedControl, context: NSViewRepresentableContext<MySegmentControl>) { } class Coordinator { let parent: MySegmentControl init(parent: MySegmentControl) { self....

Issue #627 Algorithm from https://www.w3.org/WAI/ER/WD-AERT/#color-contrast extension NSColor { var isLight: Bool { guard let components = cgColor.components, components.count >= 3 else { return false } let brightness = ((components[0] * 299) + (components[1] * 587) + (components[2] * 114)) / 1000 return brightness > 0.5 } } Then we can apply contrast color for our Text extension Text { func applyColorBaseOnBackground(_ color: NSColor?) -> some View { guard let color = color else { return self } if color....

Issue #626 SwiftUI does not trigger onAppear and onDisappear like we expect. We can use NSView to trigger import SwiftUI struct AppearAware: NSViewRepresentable { var onAppear: () -> Void func makeNSView(context: NSViewRepresentableContext<AppearAware>) -> AwareView { let view = AwareView() view.onAppear = onAppear return view } func updateNSView(_ nsView: AwareView, context: NSViewRepresentableContext<AppearAware>) { } } final class AwareView: NSView { private var trigged: Bool = false var onAppear: () -> Void = {} override func viewDidMoveToSuperview() { super....

Issue #625 For some strange reasons, content inside ForEach does not update with changes in Core Data NSManagedObject. The workaround is to introduce salt, like UUID just to make state change struct NoteRow: View { let note: Note let id: UUID } List { ForEach(notes) { note in NoteRow(note: note, id: UUID()) } } Updated at 2020-11-20 03:29:39

Issue #624 By default the approaches above grant you access while the app remains open. When you quit the app, any folder access you had is lost. To gain persistent access to a folder even on subsequent launches, we’ll have to take advantage of a system called Security-Scoped Bookmarks. Add entitlements Use of app-scoped bookmarks and URLs <key>com.apple.security.files.user-selected.read-only</key> <true/> <key>com.apple.security.files.bookmarks.app-scope</key> <true/> Enabling Security-Scoped Bookmark and URL Access If you want to provide your sandboxed app with persistent access to file system resources, you must enable security-scoped bookmark and URL access....

Issue #622 Read Implementing Batch Deletes If the entities that are being deleted are not loaded into memory, there is no need to update your application after the NSBatchDeleteRequest has been executed. However, if you are deleting objects in the persistence layer and those entities are also in memory, it is important that you notify the application that the objects in memory are stale and need to be refreshed. To do this, first make sure the resultType of the NSBatchDeleteRequest is set to NSBatchDeleteRequestResultType....

Issue #620 For NSWindow having levelother than .normal, need to override key and main property to allow TextField to be focusable class FocusWindow: NSWindow { override var canBecomeKey: Bool { true } override var canBecomeMain: Bool { true } } Furthermore to customize TextField, consider using custom import SwiftUI import AppKit struct MyTextField: NSViewRepresentable { @Binding var text: String func makeNSView(context: NSViewRepresentableContext<MyTextField>) -> NSTextField { let tf = NSTextField() tf.focusRingType = ....

Issue #618 Create custom Binding List { ForEach(self.items) { (item: item) in ItemRowView(item: item) .popover(isPresented: self.makeIsPresented(item: item)) { ItemDetailView(item: item) } } } func makeIsPresented(item: Item) -> Binding<Bool> { return .init(get: { return self.selectedId == item.id }, set: { _ in self.selectedId = nil }) }

Issue #617 On macOS 11, we can use .help modifier to add tooltip Button() .help("Click here to open settings") If you support macOS 10.15, then create empty NSView and use as overlay. Need to updateNSView in case we toggle the state of tooltip import SwiftUI struct Tooltip: NSViewRepresentable { let tooltip: String func makeNSView(context: NSViewRepresentableContext<Tooltip>) -> NSView { let view = NSView() view.toolTip = tooltip return view } func updateNSView(_ nsView: NSView, context: NSViewRepresentableContext<Tooltip>) { nsView....

Issue #612 Use runModal This method runs a modal event loop for the specified window synchronously. It displays the specified window, makes it key, starts the run loop, and processes events for that window. (You do not need to show the window yourself.) While the app is in that loop, it does not respond to any other events (including mouse, keyboard, or window-close events) unless they are associated with the window....

Issue #611 enum WindowPosition: String, CaseIterable { case left case top case bottom case right } Picker(selection: $preference.position, label: Text("Position")) { ForEach(WindowPosition.allCases, id: \.self) { Text($0.rawValue) } }
