@available(macCatalyst 18.1, *) @available(iOS 18.1, *) extension CKImageSelectionManager: ImagePlaygroundViewController.Delegate { public func imagePlaygroundViewController(_ imagePlaygroundViewController: ImagePlaygroundViewController, didCreateImageAt imageURL: URL) { } func presentImagePlayground() { let imagePlaygroundVC = ImagePlaygroundViewController() // Set delegate to self to receive the callback imagePlaygroundVC.delegate = self imagePlaygroundVC.isModalInPresentation = true // Prevents dismissal with swipe if needed self.delegate?.presentImageSelectionViewController(imagePlaygroundVC) } } This generates an error in the xcode generated swift header.

I am using a AttributedString for markdown. When I add the attributed text, it previews correctly. However, when tapping on the URL it fails to load. Bug or not? I'll post a feedback if so. class ViewController: UIViewController { let string = """ **Thank you** and please _visit_ our [Website](https://www.website.com). ```for item in items``` ```let item one be something``` ```end``` ~~Strikethrough~~ """ @IBOutlet weak var label: UILabel! override func viewDidLoad() { super.viewDidLoad() if let attributedText = try? NSMutableAttributedString(markdown: string, options: AttributedString.MarkdownParsingOptions(interpretedSyntax: .inlineOnlyPreservingWhitespace)) { let range = NSRange(location: 0, length: attributedText.mutableString.length) attributedText.addAttribute(NSAttributedString.Key.font, value: UIFont.preferredFont(forTextStyle: .title3), range: range) label.attributedText = attributedText } } }

When I try to start catalyst app in Big Sur B6, this error is immediately throw. Tested two differing apps on two differing Macs. The operation couldn’t be completed. (OSStatus error -10670.)

I can easily verify the on device receipt hash using OpenSSL on iOS. However, it's failing on Catalyst.The following code chunk works perfectly on iOS and has for several years. I reported this: FB7470452- (BOOL)verifyReceiptHash{ NSUUID *uuid = [UIDevice currentDevice].identifierForVendor; unsigned char uuidBytes[16]; [uuid getUUIDBytes:uuidBytes]; NSMutableData *data = [NSMutableData data]; [data appendBytes:uuidBytes length:sizeof(uuidBytes)]; [data appendData:self.opaqueValue]; [data appendData:self.bundleIdentifierData]; NSMutableData *expectedHash = [NSMutableData dataWithLength:SHA_DIGEST_LENGTH]; //20 SHA1((const uint8_t*)data.bytes, data.length, (uint8_t*)expectedHash.mutableBytes); return [expectedHash isEqualToData:self.receiptHash];}I'm not certain [UIDevice currentDevice].identifierForVendor is returning the correct UUID. Even when using a chunk of code to get the correct UUID (matches up in with system information), the verify still fails.Is there something special about Catalyst?
