Problems compiling xcframeworks using Carthage with the latest Xcode beta
I use Carthage to build a set of dependencies. I generate .xcframework files with code for both macOS and iOS. This works through Xcode 26 beta 4. With Xcode 26 beta 5, the resulting .xcframework files seem to have code only for iOS, not macOS. Each framework has a ios-arm64 directory and a ios-arm64_x86_64-simulator directory, but no macos-arm64_x86_64 directory. This is affecting 3 of my 7 cross-platform dependencies that I compile with Carthage. What those 3 seem to have in common is that each has one target and scheme for the shared library – instead of one for iOS and another for macOS. I may have to create a second scheme and target in each of these dependencies, or move to SPM. But I am wondering if anyone has another suggestion. Thank you. John

Registering custom fonts from a framework in a widget extension
I want a widget to use the same custom fonts that the containing app uses. I do not want multiple copies of the font files in the app bundle. I put the font files into a framework shared by the app and the widget extension. I have code to register the fonts from the framework bundle using CTFontManagerRegisterGraphicsFont. That works from the app, but it does not work from the widget extension because it requires UIKit. (At least I think that's why it doesn't seem to work from my widget extension.) Widgets cannot run UIKit code. Is there a way to programmatically register the fonts in a widget? If not is there a way I can make a UIAppFonts Info.plist entry point to a framework?

Trying to use UIScrollEdgeElementContainerInteraction
I have a UIKit app with a custom navigation controller. I want my view title to go up into the navigation bar when the user scrolls down the screen. It looks like UIScrollEdgeElementContainerInteraction should do what I want, but I am having trouble using it. Below is a sample, where a header view represents a title. I added the interaction to the header view, but it seems to have no effect. Am I missing a step? Perhaps I misunderstand what this is supposed to do, or perhaps I do not understand the preconditions to make this work. I am hoping someone can tell me what I am doing wrong, or point me to some working sample code. Thank you. John class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate { var headerView: UIVisualEffectView! var tableView: UITableView! var interaction: UIScrollEdgeElementContainerInteraction! override func viewDidLoad() { super.viewDidLoad() self.tableView = UITableView() self.tableView.translatesAutoresizingMaskIntoConstraints = false self.tableView.topEdgeEffect.style = .soft self.tableView.delegate = self self.tableView.dataSource = self self.tableView.register(UITableViewCell.self, forCellReuseIdentifier: "cell") self.view.addSubview(self.tableView) self.view.addConstraints([ self.tableView.topAnchor.constraint(equalTo: self.view.topAnchor), self.tableView.leadingAnchor.constraint(equalTo: self.view.leadingAnchor), self.tableView.trailingAnchor.constraint(equalTo: self.view.trailingAnchor), self.tableView.bottomAnchor.constraint(equalTo: self.view.bottomAnchor), ]) self.headerView = UIVisualEffectView(effect: UIGlassEffect(style: .regular)) self.headerView.translatesAutoresizingMaskIntoConstraints = false self.headerView.backgroundColor = .green self.view.addSubview(self.headerView) self.view.addConstraints([ self.headerView.topAnchor.constraint(equalTo: self.view.topAnchor), self.headerView.leadingAnchor.constraint(equalTo: self.view.leadingAnchor), self.headerView.trailingAnchor.constraint(equalTo: self.view.trailingAnchor), self.headerView.heightAnchor.constraint(equalToConstant: 100.0), ]) let label = UILabel() label.translatesAutoresizingMaskIntoConstraints = false label.text = "my text" self.headerView.contentView.addSubview(label) self.headerView.contentView.addConstraints([ label.centerXAnchor.constraint(equalTo: self.headerView.contentView.centerXAnchor), label.centerYAnchor.constraint(equalTo: self.headerView.contentView.centerYAnchor), ]) self.interaction = UIScrollEdgeElementContainerInteraction() self.interaction.scrollView = self.tableView self.interaction.edge = .top self.headerView.addInteraction(self.interaction) } func numberOfSections(in tableView: UITableView) -> Int { return 1 } func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { return 100 } func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { let cell = self.tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) cell.textLabel?.text = "row \(indexPath.row + 1)" return cell } }
