Follow up question to this. I am trying to do something similar -- create an iOS app that train conductors will use, and they would need to scan people's transit cards in the app to check how much credit they have left on their transit card. Most people have set their transit cards on express mode (no need for biometric authentication). My question is, using the NFC & SE Platform entitlement, can developers read transit cards without it requiring user authentication? Or does the user need to unlock their phone before scanning, even if it is set to express mode?

I found the solution so keeping it up in case in helps anyone else. I had this code: await withTaskGroup(of: Void.self) { group in for file in referenceObjectFiles { let objectURL = Bundle.main.bundleURL.appending(path: file) group.addTask { await self.loadReferenceObject(objectURL) await self.finishedOneFile() } } } and it worked when I replaced it with this: for file in referenceObjectFiles { let objectURL = Bundle.main.bundleURL.appendingPathComponent(file) Task { await self.loadReferenceObject(objectURL) await self.finishedOneFile() } } I guess you can't use withTaskGroup in Xcode 16...
