UISplitViewController displays button to change the display mode even when presentsWithGesture = false
I have a document-based app which displays a view controller with a navigation bar (i.e. it's inside a navigation controller) which is also the detail view controller of a split view controller. I'm using this sample code to just show a back button in the navigation bar of the document view controller: class DocumentViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() splitViewController!.presentsWithGesture = false navigationItem.backAction = UIAction(handler: { _ in }) } } In a regular width, this works as expected: only the back button is displayed. In a compact width such as a portrait iPhone, the split view seems to display the navigation bar button to show the master view controller (the one with the icon to the right of the back button, labeled “Root View Controller"). According to the documentation of presentsWithGesture: When this property is false, the split view controller doesn’t install a gesture recognizer for changing the display mode. The split view controller also doesn’t display a button to change the display mode. Is this a bug, or an error in the documentation, or am I doing something wrong?

UIResponder.printContent(_:) is not called when tapping Print in navigation item title menu
By following the documentation, in Info.plist I have added UIApplicationSupportsPrintCommand = true, but when tapping the navigation item's title and selecting Print, printContent(_:) is never called. On the other hand, when selecting Move, move(_:) is called as expected. What's the problem? The issue can be reproduced by using the code below in a newly created Xcode project with the App template. class ViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() navigationItem.title = "asdf" navigationItem.documentProperties = UIDocumentProperties(url: URL(fileURLWithPath: "/asdf")) navigationItem.titleMenuProvider = { suggestions in return UIMenu(children: suggestions) } } override func move(_ sender: Any?) { print("move") } override func printContent(_ sender: Any?) { print("printContent") } }

Force app interface style in Xcode UI tests with iOS target to be light or dark
In my UI test I'm trying to force the app's user interface style to be light or dark. On macOS, when the system appearance is light, I can force the app to be dark with this code: var app = XCUIApplication() app.launchArguments += ["-AppleInterfaceStyle", "Dark"] app.launch() Sadly, this doesn't work with a iOS target, and UIScreen.main.traitCollection.userInterfaceStyle is read-only. Is this not possible?

Simulate arrow key press in UITextView during UI test
I would like to simulate pressing an arrow key on the hardware keyboard attached to an iPad. In a UI test for a macOS target I can do this: XCUIElement.typeKey(.rightArrow, modifierFlags: [.option, .command]) but this won't compile for a iOS target supporting iPhone and iPad. Is there an alternative? What I would like to achieve in the end is moving the text cursor at the beginning of a particular sentence by pressing Option-Command-Arrow left a certain number of times, but if someone knows a better way, I'd be happy to hear it.

Determinate spinning NSProgressIndicator doesn't adapt to frame size and gets cut off
The following code should produce 6 spinning progress indicators of varying sizes: 3 indeterminate and 3 determinate ones. The first two of the 3 determinate ones are either entirely or partially cut off, which doesn't happen with the indeterminate ones. What's the problem? var progress = NSProgressIndicator(frame: CGRect(x: 0, y: 0, width: 16, height: 16)) progress.style = .spinning view.addSubview(progress) progress = NSProgressIndicator(frame: CGRect(x: 50, y: 0, width: 24, height: 24)) progress.style = .spinning view.addSubview(progress) progress = NSProgressIndicator(frame: CGRect(x: 100, y: 0, width: 32, height: 32)) progress.style = .spinning view.addSubview(progress) progress = NSProgressIndicator(frame: CGRect(x: 150, y: 0, width: 16, height: 16)) progress.style = .spinning progress.isIndeterminate = false progress.doubleValue = 50 progress.maxValue = 100 view.addSubview(progress) progress = NSProgressIndicator(frame: CGRect(x: 200, y: 0, width: 24, height: 24)) progress.style = .spinning progress.isIndeterminate = false progress.doubleValue = 50 progress.maxValue = 100 view.addSubview(progress) progress = NSProgressIndicator(frame: CGRect(x: 250, y: 0, width: 32, height: 32)) progress.style = .spinning progress.isIndeterminate = false progress.doubleValue = 50 progress.maxValue = 100 view.addSubview(progress)

Mismatching screenshot display types between App Store Connect website and API
When I open an iOS app in the App Store Connect website and disclose the Apple Watch section, it reads Apple Watch Ultra, Series 8, 6, 3, but the documentation for the API lists different versions: APP_WATCH_ULTRA APP_WATCH_SERIES_7 APP_WATCH_SERIES_4 APP_WATCH_SERIES_3 So the Watch Series don't seem to match. There is a similar issue with iPad Pro. The website reads iPad Pro (6th Gen) 12.9" Display and iPad Pro (2nd Gen) 12.9" Display, but the API reads APP_IPAD_PRO_3GEN_129 APP_IPAD_PRO_129 So again the Gen values don't seem to match. How should I interpret these values?

App Store Connect API: why do I only have to provide a checksum when uploading app screenshots and not for app event screenshots?
When uploading app screenshots, I have to provide a sourceFileChecksum and uploaded flag: https://developer.apple.com/documentation/appstoreconnectapi/appscreenshotupdaterequest/data/attributes But that's not the case for app event screenshots, I only have to provide the uploadedflag: https://developer.apple.com/documentation/appstoreconnectapi/appeventscreenshotupdaterequest/data/attributes The same is true for app previews and app event video clips. Why is this different?

Xcode shows compiler errors when accessing class properties and methods only when class is in separate file
When building the code below, two compiler errors appear in AppDelegate.swift: Value of type 'Slice<MyCollection<MySubCollection>>' has no member 'url' No exact matches in call to instance method 'remove' When moving the first 2 classes in ViewController.swift to AppDelegate.swift, the issues go away. Is this expected, or a bug? // AppDelegate.swift // import Cocoa @main class AppDelegate: NSObject, NSApplicationDelegate { func applicationDidFinishLaunching(_ aNotification: Notification) { var collection: MyCollection<MySubCollection>! let a = collection.first!.url! var subCollection: MySubCollection! collection.remove(subCollection) } } // // ViewController.swift // import Cocoa class MyCollection<Element>: MyCollectionProtocol { var elements = [Element]() } class MySubCollection: MyCollectionProtocol { var elements = [String]() var url: URL? } protocol MyCollectionProtocol: AnyObject, Collection where Index == Int { associatedtype Element var elements: [Element] { get set } } extension MyCollectionProtocol { var startIndex: Index { return elements.startIndex } var endIndex: Index { return elements.endIndex } subscript(position: Index) -> Element { return elements[position] } func index(after i: Index) -> Index { return elements.index(after: i) } } extension MyCollectionProtocol where Element == String { func remove(_ element: Element) { } } extension MyCollectionProtocol where Element: MyCollectionProtocol { func remove(_ element: Element) { } }

Autosizing text field: NSCell.cellSize(forBounds:) doesn't respect wrapped text unless using attributed string
I'm trying to implement a text field in a table view that automatically adjusts its height to fit the contained text. My current implementation adjusts its intrinsicContentSize in textDidChange(_:). Unfortunately, NSCell.cellSize(forBounds:) doesn't seem to return the correct height unless setting attributedStringValue and allowsEditingTextAttributes = true for the NSTextField. Is this expected, or is there a workaround? Here is the code: class ViewController: NSViewController, NSTableViewDataSource, NSTableViewDelegate { var asdf = "asdf fjdskalöf öf fjkldösa jfklödsa kfljsaödkfj klsdajf kldöasj flkjsdöa fkljasö flkjsa öj " override func loadView() { view = NSView(frame: CGRect(x: 0, y: 0, width: 400, height: 400)) let scrollView = NSScrollView() scrollView.translatesAutoresizingMaskIntoConstraints = false let tableView = NSTableView() tableView.usesAutomaticRowHeights = true tableView.addTableColumn(NSTableColumn()) tableView.dataSource = self tableView.delegate = self scrollView.documentView = tableView view.addSubview(scrollView) NSLayoutConstraint.activate([scrollView.topAnchor.constraint(equalTo: view.topAnchor), scrollView.leadingAnchor.constraint(equalTo: view.leadingAnchor), scrollView.trailingAnchor.constraint(equalTo: view.trailingAnchor), scrollView.bottomAnchor.constraint(equalTo: view.bottomAnchor)]) } func numberOfRows(in tableView: NSTableView) -> Int { return 1 } func tableView(_ tableView: NSTableView, viewFor tableColumn: NSTableColumn?, row: Int) -> NSView? { let view = NSTableCellView() let text = AutoSizingTextField() text.translatesAutoresizingMaskIntoConstraints = false text.cell?.wraps = true // uncommenting the next 2 lines and commenting out the line after them solves the issue // text.attributedStringValue = NSAttributedString(string: asdf, attributes: [.font: text.font!, .foregroundColor: NSColor.labelColor]) // text.allowsEditingTextAttributes = true text.stringValue = asdf view.addSubview(text) NSLayoutConstraint.activate([text.leadingAnchor.constraint(equalTo: view.leadingAnchor, constant: 20), text.topAnchor.constraint(equalTo: view.topAnchor, constant: 20), text.bottomAnchor.constraint(equalTo: view.bottomAnchor, constant: -20), text.widthAnchor.constraint(equalToConstant: 200)]) return view } } class AutoSizingTextField: NSTextField { override var intrinsicContentSize: NSSize { var size = super.intrinsicContentSize guard let cell = cell else { return size } var frame = frame frame.size.height = .infinity size.height = cell.cellSize(forBounds: frame).height NSLog("intrinsicContentSize \(size)") return size } override func textDidChange(_ notification: Notification) { super.textDidChange(notification) invalidateIntrinsicContentSize() needsLayout = true layoutSubtreeIfNeeded() } override func layout() { invalidateIntrinsicContentSize() super.layout() } }

NSTextField in table view with specific configuration doesn't enable undo
After typing anything in a custom text field with undo support, when opening the Edit menu, the undo item is disabled. It seems that setting translatesAutoresizingMaskIntoConstraints=false, a formatter, allowsEditingTextAttributes=true and calling invalidateIntrinsicContentSize() in textDidChange(_:) causes this behaviour. Is this expected, or is there a workaround? Here is the code: class ViewController: NSViewController, NSTableViewDataSource, NSTableViewDelegate { @IBOutlet weak var textField: NSTextField! override func loadView() { view = NSView(frame: CGRect(x: 0, y: 0, width: 400, height: 400)) let textField = MyTextField() textField.frame = CGRect(x: 0, y: 0, width: 100, height: 20) textField.translatesAutoresizingMaskIntoConstraints = false textField.formatter = MyFormatter() textField.allowsEditingTextAttributes = true view.addSubview(textField) } } class MyTextField: NSTextField { override func textDidChange(_ notification: Notification) { super.textDidChange(notification) super.invalidateIntrinsicContentSize() } } class MyFormatter: Formatter { override func string(for obj: Any?) -> String? { return obj as? String } override func getObjectValue(_ obj: AutoreleasingUnsafeMutablePointer<AnyObject?>?, for string: String, errorDescription error: AutoreleasingUnsafeMutablePointer<NSString?>?) -> Bool { obj?.pointee = string as NSString return true } }

Vertical text from left to right with NSTextView
In the WebVTT video subtitle format, subtitles can be horizontal, vertical growing left, or vertical growing right. The natural text direction of NSTextView is horizontal; with setLayoutOrientation(_:) I get vertical text growing left. How can I get vertical text growing right? The documentation says that with setLayoutOrientation(_:) the text view's bounds are rotated by 90° clockwise, but manually rotating them by -90° with boundsRotation = -90 just rotates everything, including the text which should have the same orientation as before, just expanding in the opposite direction.

NSTextField and NSParagraphStyle: right align left-to-right text and left align right-to-left text
NSTextField and NSParagraphStyle have a alignment: NSTextAlignment property that allows to align text to the left, center, right, or natural, which means that text for left-to-right languages is aligned left and text for right-to-left languages is aligned right. What I'm looking for is how to align text in the opposite direction of the natural direction. (Note that using the leading and trailing NSLayoutConstraints is not enough as they only aligns the text bounding box, but not the text within the bounding box.) Is there a way to accomplish this? Or is there a built-in function that allows to determine what the natural direction of a String is, so that I can then calculate the alignment by flipping that value?

Comparing local and uploaded app screenshots with App Store Connect API
Is there a way to compare a local app screenshot on my Mac with the one currently on App Store Connect without downloading the screenshot itself? The API returns fileSize and sourceFileChecksum properties (https://developer.apple.com/documentation/appstoreconnectapi/read_app_screenshot_information), but the file size of my local image is different (url.resourceValues(forKeys: [.fileSizeKey]).fileSize) and the checksum is also different from the one I provided when completing the app screenshot upload.

NSTextField frame automatically hugs content when superview is AVPlayerView.contentOverlayView
I need to manually set the frame of a NSTextField, but it seems that when added to AVPlayerView.contentOverlayView the frame gets resized so that it hugs the text. This doesn't happen when the text field is added to a simple NSView instead. Is this a bug? Is there a workaround? class ViewController: NSViewController { override func loadView() { view = NSView() let text = NSTextField(frame: CGRect(x: 0, y: 0, width: 200, height: 30)) text.translatesAutoresizingMaskIntoConstraints = false text.isEditable = false text.backgroundColor = .red let paragraph = NSMutableParagraphStyle() paragraph.alignment = .center text.attributedStringValue = NSAttributedString(string: "asdf", attributes: [.paragraphStyle: paragraph]) view.addSubview(text) // commenting out the following 3 lines solves the issue let playerView = AVPlayerView(frame: CGRect(x: 0, y: 0, width: 200, height: 200)) view.addSubview(playerView) playerView.contentOverlayView!.addSubview(text) // uncommenting the following 5 lines also solves the issue, but the wrong text field frame is briefly visible before it resizes to the correct width // DispatchQueue.main.async { // print(text.frame) // text.frame.size.width = 200 // text.removeConstraints(text.constraints) // } } }
