Hi, I keep trying to use transformable to store an array of strings with SwiftData, and I can see that it is activating the transformer, but it keeps saying that I am still using NSArray instead of NSData. *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Unacceptable type of value for attribute: property = "category"; desired type = NSData; given type = Swift.__SwiftDeferredNSArray; value = ( yo, gurt ).' terminating due to uncaught exception of type NSException CoreSimulator 1010.10 - Device: iPhone 16 18.0 (6879535B-3174-4025-AD37-ED06E60291AD) - Runtime: iOS 18.0 (22A3351) - DeviceType: iPhone 16 Message from debugger: killed @Model class MyModel: Identifiable, Equatable { @Attribute(.transformable(by: StringArrayTransformer.self)) var category: [String]? @Attribute(.transformable(by: StringArrayTransformer.self)) var amenities: [String]? var image: String? var parentChunck: HenricoPostDataChunk_V1? init(category: [String]?, amenities: [String]?) { self.category = category self.amenities = amenities } } class StringArrayTransformer: ValueTransformer { override func transformedValue(_ value: Any?) -> Any? { print(value) guard let array = value as?

Whenever I load a resized image into a 70 by 70 frame, when I run the loading screen on the simulator, it looks like the image is flying from the top left corner of the screen on load, however, when I load it in the previews, it starts where its supposed to be in the center. Both are scaled properly, however, the first ones position is acting like I put a transition on it when I did not import SwiftUI struct LoadingView: View { @Environment(\.colorScheme) private var colorScheme var text: String? = nil @State private var isSpinning = false var body: some View { VStack{ Image("Jeromes_Logo") .resizable() .frame(width: 70, height: 70) .rotationEffect(.degrees(isSpinning ? 360 : 0)) .animation( .bouncy(duration: 0.4, extraBounce: 0.2) .repeatForever(autoreverses: false), value: isSpinning ) .onAppear { isSpinning = true } if let text = text { Text(text) } } .frame(maxWidth: .infinity, maxHeight: .infinity) } } #Preview { LoadingView(text: "loading") }

Hello everyone, I am having an issue where the attributed text that I have in my UITextView is not scaling dynamically with phone text size, whenever I remove the attributed text logic, it scales fine, however, with it, it stays at a set font size. struct AutoDetectedClickableDataView: UIViewRepresentable { let text: String @Binding var height: CGFloat func makeUIView(context: Context) -> UITextView { let textView = UITextView() textView.dataDetectorTypes = [.phoneNumber, .address, .link] textView.isEditable = false textView.isScrollEnabled = false textView.backgroundColor = .clear textView.font = UIFont.preferredFont(forTextStyle: .body) /*UIFontMetrics(forTextStyle: .body).scaledFont(for: UIFont.systemFont(ofSize: 16.0)) */ textView.adjustsFontForContentSizeCategory = true textView.textContainer.lineBreakMode = .byWordWrapping textView.textContainerInset = .zero textView.textContainer.lineFragmentPadding = 0 textView.translatesAutoresizingMaskIntoConstraints = false textView.setContentCompressionResistancePriority(.defaultLow, for: .horizontal) textView.setContentHuggingPriority(.defaultHigh, for: .horizontal) return textView } func updateUIView(_ uiView: UITextView, context: Context) { let attributed = NSMutableAttributedString(string: text, attributes: [ .font: UIFont.preferredFont(forTextStyle: .body) ]) let detector = try? NSDataDetector(types: NSTextCheckingResult.CheckingType.address.rawValue | NSTextCheckingResult.CheckingType.link.rawValue | NSTextCheckingResult.CheckingType.phoneNumber.rawValue) detector?.enumerateMatches(in: text, options: [], range: NSRange(location: 0, length: text.utf16.count)) { match, _, _ in guard let match = match else { return } attributed.addAttributes([ .foregroundColor: UIColor.systemBlue, .underlineStyle: NSUnderlineStyle.single.rawValue, ], range: match.range) } uiView.attributedText = attributed // uiView.text = text DispatchQueue.main.async { uiView.layoutIfNeeded() let fittingSize = CGSize(width: uiView.bounds.width, height: .greatestFiniteMagnitude) let size = uiView.sizeThatFits(fittingSize) height = size.height } } }

I am currently having an issue in where whenever I place a UITextView with text that's long, it simply pushes past the width of the container it is in, and when I do try and set a width, it does auto wrap and ignores that. I do not come from UIKit and come from SwiftUI, through a mix of ChatGPT and Stack overflow, I have come up with this solution, however, are there any better/simpler ones, I dont want to have to use expensive GeoReaders just to get a width. struct AutoDetectedPhoneNumberView: UIViewRepresentable { let text: String var width: CGFloat func makeUIView(context: Context) -> UITextView { let textView = UITextView() textView.dataDetectorTypes = [.phoneNumber] textView.isEditable = false textView.isScrollEnabled = false textView.backgroundColor = .clear textView.font = UIFont.systemFont(ofSize: 16) textView.textContainer.lineBreakMode = .byWordWrapping textView.translatesAutoresizingMaskIntoConstraints = false print(width) NSLayoutConstraint.activate([ textView.widthAnchor.constraint(equalToConstant: width) ]) return textView } func updateUIView(_ uiView: UITextView, context: Context) { uiView.text = text } } GeometryReader { geo in AutoDetectedPhoneNumberView(text: phone, width: geo.size.width) }

I currently have a custom UITextView that properly changes the color of a link to the custom color I have set, however, when I click and hold the link, and the animation plays that makes the link bigger and creates a boarder around the link before previewing the website, the link changes briefly back to the system default color, and when letting go, it changes back to my custom color. Is there anyway to have the link always be my custom color, even when clicking and holding? struct AutoDetectedClickableDataView: UIViewRepresentable { let text: String let dataDetectors: UIDataDetectorTypes @Binding var height: CGFloat private func dataDectectorValue(_ dataDectecor: UIDataDetectorTypes) -> UInt64 { var checkingTypes: [NSTextCheckingResult.CheckingType] = [] if dataDetectors.contains(.phoneNumber) { checkingTypes.append(.phoneNumber) } if dataDetectors.contains(.link) { checkingTypes.append(.link) } if dataDetectors.contains(.address) { checkingTypes.append(.address) } if dataDetectors.contains(.calendarEvent) { checkingTypes.append(.date) } if checkingTypes.isEmpty { return 0 } let intCheckingTypes: UInt64 = checkingTypes.reduce(0) { result, checkingType in UInt64(result) | UInt64(checkingType.rawValue) } return intCheckingTypes } func makeUIView(context: Context) -> UITextView { let textView = UITextView() textView.dataDetectorTypes = dataDetectors textView.isEditable = false textView.isScrollEnabled = false textView.backgroundColor = .clear textView.font = UIFontMetrics(forTextStyle: .body).scaledFont(for: UIFont.systemFont(ofSize: 16.0), compatibleWith: textView.traitCollection) textView.textColor = UIColor.label textView.adjustsFontForContentSizeCategory = true textView.textContainer.lineBreakMode = .byWordWrapping textView.textContainerInset = .zero textView.textContainer.lineFragmentPadding = 0 textView.translatesAutoresizingMaskIntoConstraints = false textView.setContentCompressionResistancePriority(.defaultLow, for: .horizontal) textView.setContentHuggingPriority(.defaultHigh, for: .horizontal) textView.linkTextAttributes = [.foregroundColor: JeromesColors.UILinkColor] textView.tintColor = JeromesColors.UILinkColor for gesture in textView.gestureRecognizers ?? [] { if gesture is UITapGestureRecognizer { gesture.view?.tintColor = JeromesColors.UILinkColor } } return textView } func updateUIView(_ uiView: UITextView, context: Context) { let font = UIFontMetrics(forTextStyle: .body).scaledFont(for: UIFont.systemFont(ofSize: 16.0), compatibleWith: uiView.traitCollection) let color = UIColor.label let attributed = NSMutableAttributedString(string: text, attributes: [ .font: font, .foregroundColor: color ]) let detectorValue = dataDectectorValue(dataDetectors) var matchCount = 0 if !dataDetectors.isEmpty, detectorValue != 0 { let detector = try? NSDataDetector(types: detectorValue) detector?.enumerateMatches(in: text, options: [], range: NSRange(location: 0, length: text.utf16.count)) { match, _, _ in guard let match = match else { return } if match.resultType == .date, let date = match.date, date < Date() { return } else { attributed.addAttributes([ .foregroundColor: JeromesColors.UILinkColor, .underlineStyle: NSUnderlineStyle.single.rawValue, ], range: match.range) matchCount += 1 } } } uiView.attributedText = attributed if matchCount == 0 { uiView.isSelectable = false } else if matchCount > 0 { uiView.isSelectable = true } DispatchQueue.main.async { uiView.layoutIfNeeded() let fittingSize = CGSize(width: uiView.bounds.width, height: .greatestFiniteMagnitude) let size = uiView.sizeThatFits(fittingSize) height = size.height } } }
