Issue #773 From John Harper ’s tweet SwiftUI assumes any Equatable.== is a true equality check, so for POD views it compares each field directly instead (via reflection). For non-POD views it prefers the view’s == but falls back to its own field compare if no ==. EqView is a way to force the use of ==. When it does the per-field comparison the same rules are applied recursively to each field (to choose direct comparison or == if defined)....

Issue #772 I use Codable structs in my apps for preferences, and bind them to SwiftUI views. If we add new properties to existing Codable, it can’t decode with old saved json as we require new properties. We can either do cutom decoding with container, but this can result in lots more code and mistakes if we have many properties inside our struct. The quick workaround is to declare new properties as optional, and use a computed property to wrap that....

Issue #769 If we place ScrollView inside HStack or VStack, it takes all remaining space. To fit ScrollView to its content, we need to get its content size and constrain ScrollView size. Use a GeometryReader as Scrollview content background, and get the local frame import SwiftUI struct HSearchBar: View { @State private var scrollViewContentSize: CGSize = .zero var body: some View { HStack { searchButton ScrollView(.horizontal, showsIndicators: false) { HStack(spacing: 12) { ForEach(store....

Issue #768 Use custom NSWindow, set level in becomeKey and call NSApp.runModal to show modal final class ModalWindow: NSWindow { override func becomeKey() { super.becomeKey() level = .statusBar } override func close() { super.close() NSApp.stopModal() } } let window = ModalWindow( contentRect: .zero, styleMask: [.titled, .closable], backing: .buffered, defer: false ) window.titlebarAppearsTransparent = true window.title = "Manage collections" window.center() window.isReleasedWhenClosed = false self.window = window let view = CollectionSettingsView(store: Store.shared) ....

Issue #767 SwiftUI ’s ViewBuilder is a custom parameter attribute that constructs views from closures. It is available in body and most SwiftUI modifiers public protocol View { associatedtype Body : View @ViewBuilder var body: Self.Body { get } } public func contextMenu<MenuItems>(@ViewBuilder menuItems: () -> MenuItems) -> some View where MenuItems : View In these ViewBuilder enabled places we can perform conditional logic to construct views. For example here in our SampleView, we have switch statement in body...

Issue #766 Need to use a class, best is to subclass from NSObject let cache = NSCache<Key, UIImage>() final class Key: NSObject { override func isEqual(_ object: Any?) -> Bool { guard let other = object as?

Issue #765 In SwiftUI currently, it’s not possible to attach multiple .popover to the same View. But we can use condition to show different content struct ClipboardCell: View { enum PopoverStyle { case raw case preview } @Binding var showsPopover: Bool @Binding var popoverStyle: PopoverStyle var body: some View { VStack { header content .popover(isPresented: $showsPopover) { switch popoverStyle { case .raw: ViewRawView(item: item) case .preview: PreviewView(item: item) } } footer } } } ...

Issue #764 Use a custom KeyAwareView that uses an NSView that checks for keyDown method. In case we can’t handle certain keys, call super.keyDown(with: event) import SwiftUI import KeyboardShortcuts struct KeyAwareView: NSViewRepresentable { let onEvent: (Event) -> Void func makeNSView(context: Context) -> NSView { let view = KeyView() view.onEvent = onEvent DispatchQueue.main.async { view.window?.makeFirstResponder(view) } return view } func updateNSView(_ nsView: NSView, context: Context) {} } extension KeyAwareView { enum Event { case upArrow case downArrow case leftArrow case rightArrow case space case delete case cmdC } } private class KeyView: NSView { var onEvent: (KeyAwareView....

Issue #763 I usually break down a big struct into smaller views and extensions. For example I have a ClipboardCell that has a lot of onReceive so I want to move these to another component. One way to do that is to extend ClipboardCell struct ClipboardCell: View { let isSelected: Bool @State var showsPreview: Bool @State var showsViewRaw: Bool let onCopy: () -> Void let onDelete: () -> Void } extension ClipboardCell { func onReceiveKeyboard() -> some View { self....
