Issue #806 Use runModal https://developer.apple.com/documentation/appkit/nsapplication/1428590-runmodalsession Blocks main queue A loop that uses this method is similar in some ways to a modal event loop run with runModal(for:), except with this method your code can do some additional work between method invocations. When you invoke this method, events for the NSWindow object of this session are dispatched as normal. This method returns when there are no more events. You must invoke this method frequently enough in your loop that the window remains responsive to events....

Issue #805 Use LongPressGesture to detect when long-press gesture has been recognized, and chain with DragGesture to check when pressing still occurs Image(systemName: SFSymbol.deleteLeft.rawValue) .imageScale(.medium) .onTapGesture { onKeyCommand(.backspace) } .gesture( LongPressGesture() .onEnded { _ in self.timer = Timer.scheduledTimer(withTimeInterval: 0.1, repeats: true) { _ in self.onKeyCommand(.backspace) } } .sequenced( before: DragGesture(minimumDistance: 0) .onEnded { _ in self.timer?.invalidate() self.timer = nil } ) )

Issue #799 Besides coming up with a good idea and building the app, there are many other things you can do to boost your apps’ visibility Twitter thread https://twitter.com/onmyway133/status/1387851727714635776 Thread reader https://threadreaderapp.com/thread/1387851727714635776.html

Issue #796 One seemingly obvious way to use ForEach on array with indices is using enumerated struct Book: Hashable, Identifiable { let id: UUID let name: String } struct BooksView: View { let books: [Book] var body: some View { List { ForEach(Array(books.enumerated()), id: \.element) { index, book in Text(book.name) .background(index % 2 == 0 ? Color.green : Color.orange) } } } } Reading the documentation for enumerated closely When you enumerate a collection, the integer part of each pair is a counter for the enumeration, but is not necessarily the index of the paired value....

Issue #795 extension NSImage { func resize(width: CGFloat, height: CGFloat, padding: CGFloat) -> NSImage { let img = NSImage(size: CGSize(width: width, height: height)) img.lockFocus() let ctx = NSGraphicsContext.current ctx?.imageInterpolation = .high self.draw( in: NSMakeRect(0, 0, width, height), from: NSMakeRect(0, -padding, size.width, size.height - padding), operation: .copy, fraction: 1 ) img.unlockFocus() return img } } So we can use like button.image = NSImage(named: NSImage.Name("pastePal"))?.resize(width: 22, height: 22, padding: -4)

Issue #794 I’ve been distributing my apps PastePal and Push Hero as a paid upfront apps on Appstore. I’ve quickly come to realize the importance of trials since many have requested a tryout before purchasing. Manual sending out trials comes with its own problem. I need to notarize and package the app as a dmg file, and not to even mention implement my own trial mechanism to check and notify of expired builds....

Issue #793 To create array containing number of repeated value in Swift, we can use Array.init(repeating:count:) let fiveZs = Array(repeating: "Z", count: 5) print(fiveZs) // Prints "["Z", "Z", "Z", "Z", "Z"]" However, if we read Collection Types guide about Creating an Array with a Default Value Swift’s Array type also provides an initializer for creating an array of a certain size with all of its values set to the same default value....

Issue #792 iOS 13 introduced Dark Mode with User Interface Style that makes it easy to support dark and light theme in our apps. Before we dive in, here are some official resources WWDC 2019 Implementing Dark Mode on iOS Supporting Dark Mode in Your Interface Choosing a Specific Interface Style for Your iOS App Adaptive color Like adaptive layout that adapts to different screen sizes, adaptive colors adapt to different user interface styles, for now they are light and dark mode....

Issue #791 SwiftUI has View protocol which represents part of your app’s user interface and provides modifiers that you use to configure views. You create custom views by declaring types that conform to the View protocol. Implement the required body computed property to provide the content for your custom view. A typical example of View is using struct enum HeroType { case melee case range } struct ContentView: View { let heroType: HeroType var body: some View { switch heroType { case ....

Issue #790 Use UIImageWriteToSavedPhotosAlbum Adds the specified image to the user’s Camera Roll album. Let’s make an NSObject delegate class so we can perform target action to notify about completion import UIKit struct ImageService { final class Delegate: NSObject { let completion: (Error?) -> Void init(completion: @escaping (Error?) -> Void) { self.completion = completion } @objc func savedImage( _ im: UIImage, error: Error?, context: UnsafeMutableRawPointer? ) { DispatchQueue.main.async { self.completion(error) } } } func addToPhotos(image: UIImage, completion: @escaping (Error?...

Issue #789 Using WindowGroup New in SwiftUI 2.0 for iOS 14 and macOS 11.0 is WindwGroup which is used in App protocol. WindowGroup is ideal for document based applications where you can open multiple windows for different content or files. For example if you’re developing a text editor or drawing apps, you can show multiple windows for different text file or drawing. All is handled automatically for you if you use WindowGroup...

Issue #788 I just convert my blog https://onmyway133.com/ from Hexo.js back to Hugo again. Hugo now uses goldmark as the default markdown processor instead of blackfriday All works well, except that I use GitHub markdown to write articles, which use raw HTML img tag for uploaded images. Hugo works well with ![]() syntax but it ignores img tag <img width="574" alt="Screenshot 2021-02-26 at 10 08 38" src="https://user-images.githubusercontent.com/2284279/109279894-99d09a80-781a-11eb-9d50-10f46ba94105.png"> The solution is to tell goldmark to accept raw HTML....

Issue #787 In Swift, property, especially for Boolean flagging, uses the regular verb form for the third person. There are few exceptions, such as enable NSManagedObjectContext.automaticallyMergesChangesFromParent UIView.clipsToBounds UIView.translatesAutoresizingMaskIntoConstraints SwiftUI.Transaction.disablesAnimations UIScrollView.scrollsToTop NSView.isHidden UndoManager.enableUndoRegistration

Issue #786 Sometimes we need to update some properties between objects, for example book.name = updatedBook.name book.page = updatedBook.page book.publishedAt = updatedBook.publishedAt Repeating the caller book is tedious and error-prone. In Kotlin, there is with block which is handy to access the receiver properties and methods without referring to it. with(book) { name = updatedBook.name page = updatedBook.page publishedAt = updatedBook.publishedAt } In Swift, there are no such thing, we can write some extension like...
