Hello there, Starting from iOS 18.4, support was included for QWAC Validation and QCStatements. Using the official QWAC Validator at: https://eidas.ec.europa.eu/efda/qwac-validation-tool I was able to check that the domain "eidas.ec.europa.eu" has a valid QWAC certificate. However, when trying to obtain the same result using the new API, I do not obtain the same result. Here is my sample playground code: import Foundation import Security import PlaygroundSupport PlaygroundPage.current.needsIndefiniteExecution = true @MainActor class CertificateFetcher: NSObject, URLSessionDelegate { private let url: URL init(url: URL) { self.url = url super.init() } func start() { let session = URLSession(configuration: .ephemeral, delegate: self, delegateQueue: nil) let task = session.dataTask(with: url) { data, response, error in if let error = error { print("Error during request: \(error)") } else { print("Request completed.") } } task.resume() } nonisolated func urlSession(_ session: URLSession, didReceive challenge: URLAuthenticationChallenge, completionHandler: @escaping (URLSession.AuthChallengeDisposition, URLCredential?) -> Void) { guard let trust = challenge.protectionSpace.serverTrust else { completionHandler(.cancelAuthenticationChallenge, nil) return } if let certificates = SecTrustCopyCertificateChain(trust) as? [SecCertificate] { self.checkQWAC(certificates: certificates) } let credential = URLCredential(trust: trust) completionHandler(.useCredential, credential) } nonisolated func checkQWAC(certificates: [SecCertificate]) { let policy = SecPolicyCreateSSL(true, nil) var trust: SecTrust? guard SecTrustCreateWithCertificates(certificates as CFArray, policy, &trust) == noErr, let trust else { print("Unable to create SecTrust") return } var error: CFError? guard SecTrustEvaluateWithError(trust, &error) else { print("Trust evaluation failed") return } guard let result = SecTrustCopyResult(trust) as? [String : Any] else { print("No result dictionary") return } let qwacStatus = result[kSecTrustQWACValidation as String] let qcStatements = result[kSecTrustQCStatements as String] print("QWAC Status: \(String(describing: qwacStatus))") print("QC Statements: \(String(describing: qcStatements))") } } let url = URL(string: "https://eidas.ec.europa.eu/")! let fetcher = CertificateFetcher(url: url) fetcher.start() Which prints: QWAC Status: nil QC Statements: nil Request completed. Am I making a mistake while using the Security framework? I would greatly appreciate any help or guidance you can provide.

I’m running the interactive reordering sample from this repo and hitting an odd behavior on newer simulators: the delegate method that lets you steer the drop: func collectionView(_:targetIndexPathForMoveOfItemFromOriginalIndexPath:atCurrentIndexPath:toProposedIndexPath:) works fine on iOS 16, but on iOS 18 and iOS 26 simulators it never fires, so the item always lands at the proposed index path and I can’t constrain moves or adjust the compositional view layout to accommodate the cell of different size. Is this a new behavior in modern iOS? If so, what’s the recommended way to control the final index path for the UICollectionViewDropDelegate now?
