Since iOS 13, apps can make use of a new Fonts entitlement, with a sub option 'Use Installed Fonts' to use custom fonts installed by special font provider apps. These apps make use of the same entitlement, but with sub option 'Install Fonts'. Examples of such apps are CreativeCloud from Adobe and MyFonts from MonoType.
Using installed fonts works fine, except with WKWebView.
As an example, I use the following code to load some text in a WKWebView control, and use a UIFontPickerViewController to select a font. After selecting the font, both the font of the webView control and navigation bar are being updated. This works fine with built-in system fonts. But after selecting a custom installed font, only the font of the navigation bar is being updated. This indicates that the app supports the installed custom font, but not the WKWebView control.
class ViewController: UIViewController {
		@IBOutlet weak var webView: WKWebView!
		var font = "Avenir Next"
		let html = """
		<style>
		body {
				font-family: 'FONTFAMILY';
				font-size: 40pt;
		}
		</style>
		<body>
		This is a test string to demonstrate the characters of a custom installed font named “<b>FONTFAMILY</b>”. Hopefully it will not be replaced by Times New Roman or some other ugly looking font.
		</body>
		"""
		override func viewDidLoad() {
				super.viewDidLoad()
				loadHTML()
		}
		@IBAction func selectFont(_ sender: AnyObject) {
				let picker = UIFontPickerViewController()
				picker.delegate = self
				present(picker, animated: true, completion: nil)
		}
		fileprivate func loadHTML() {
				webView.loadHTMLString(html.replacingOccurrences(of: "FONTFAMILY", with: font), baseURL: nil)
				navigationController?.navigationBar.titleTextAttributes = [NSAttributedString.Key.font : UIFont(name: font, size: 24)!]
		}
}
extension ViewController: UIFontPickerViewControllerDelegate {
		func fontPickerViewControllerDidPickFont(_ viewController: UIFontPickerViewController) {
				if let family = viewController.selectedFontDescriptor?.object(forKey: .family) as? String			{
						font = family
						loadHTML()
				}
		}
}
Question: what must I do get those custom installed fonts working in WKWebView?
An older technique of installing custom fonts in iOS made use of configuration profiles. This works perfectly with WKWebView, but my question is about the new iOS 13 font installation technique, as explained here: https://developer.apple.com/videos/play/wwdc2019/227/

The default width of NSSearchToolbarItem is way too large. I want it to be similar to the Notes app.
Is there an official way to do this?
Setting maxSize seems to work, until I saw all kinds of layout constraint errors in the console while customising the toolbar, so that's apparently not the way to go.
My app uses CloudKit Query subscriptions and notifications as part of a CloudKit-based synchronization solution. This works perfectly with iOS 12, macOS 10.14 and even macOS 10.15 beta, but NOT with iOS 13.0, iOS 13.1 and TVOS 13.0.Is this a known problem?According to the documentation, nothing has changed with CloudKit subscriptions. Or did I miss something?

The following code doesn't work anymore in Mojave:if let url = URL(string: "https://apple.com"),
let listService = NSSharingService(named: NSSharingService.Name.addToSafariReadingList),
listService.canPerform(withItems: [url])
{
listService.perform(withItems: [url])
}The code is executed without any errors within the app, but nothing is being added to the Safari reading list. Please note that this code is just one of the many ways to show an 'Add to Reading List' item in an app. In all cases it won't work if it's 'third party' app.A lot of non-Apple apps that offer a 'Add to Reading List' share menu item, suffer from the same problem: nothing new appears in the Safari reading list.In the Console I saw a few errors indicating it is related to AppleEvent sandboxing, introduced in Mojave. So I added a NSAppleEventsUsageDescription item with a description to the Info.plist, but without any success.Does anyone know how to fix this problem?

My macOS app uses a NSTableView with 'Floats Group Row' enabled. This works without problems on my test Macs. However, on a regular basis I receive crash reports titled: *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'self.floatingGroupRowView should be equal to the given row view!'Does anyone know the conditions for this error?The last part of the crashlog look similar to this:0 CoreFoundation 0x00007fff51db6ff3 __exceptionPreprocess + 147

I have a single-column NSTableView, populated with custom NSTableCellView's, very similar to the standard Mail app of macOS. Each custom NSTableCellView has a layout with four non-selectable read-only NSTextField's. VoiceOver for Accessibility reads things left to right, top to bottom. This results in a non-optimal order for VoiceOver users.How can I change the order in which VoiceOver reads the NSTextField's within each NSTableCellView?All examples and documentation I saw about re-ordering VoiceOver elements is related to iOS, but unfortunately the API in macOS is still different.

Since macOS 10.13 we can use NSTableView with automatic row heights, thanks to the new property usesAutomaticRowHeights and of course auto layout. This works quite nicely.But when the user resizes a column, the calculated heights are no longer correct, and gaps appear in the tableview cells.Is there a proven way to update the row heights after column resize in this scenario?I already tried methods like updateConstraintsForSubtreeIfNeeded(), updateConstraints(), setNeedsDisplay(), reloadData() and so on, but nothing works.
