NSCocoaErrorDomain

[quote='796608022, DTS Engineer, /thread/759890?answerId=796608022#796608022'] Finally, how is MCPeerID coming into this? I thought you were using GameKit? [/quote] Actually, I am using both GameKit and MCSession. Trying to play with fragmenting the data, as you prompted. Although it is more or less clear how to send data: func sendData(dictionaryWithData dictionary: Dictionary, toPeer targetPeers: [MCPeerID]) { do { let dataToSend = try NSKeyedArchiver.archivedData(withRootObject: dictionary, requiringSecureCoding: true) let fragments = fragmentsForMessage(dataToSend, messageID: 0xa1a2a3a4, maxMessageBytesInFragment: 50000) for fragment in fragments { try session.send(fragment, toPeers: targetPeers, with: MCSessionSendDataMode.reliable) } } catch { } } ... I am frankly a bit stuck as to how to handle it in func session(_ session: MCSession,didReceive data: Data,fromPeer peerID: MCPeerID) { DispatchQueue.main.async { do { .... Append data to a property and then at some point implement NSDictionary.unsecureUna

Also having the very same problem here with my app: -[WCFileStorage persistOutgoingFileTransfer:] error serializing file transfer , transferring: YES> due to Error Domain=NSCocoaErrorDomain Code=4866 Caught exception during archival: This object may only be encoded by an NSXPCCoder. The file arrives at the phone but the didFinishFileTransfer on watch's delegate never gets called. Because of this, the files are kept in queue and keep being synced to phone app repeatedly consuming watch battery. Also happens on simulator. iOS 17.5.1 watchOS 10.5.
