NSCocoaErrorDomain

Same on beta 4. Btw running on device does not trigger such errors. Instead it complains about connection to some helper app: ### qid=1 error Error Domain=NSCocoaErrorDomain Code=4097 Couldn’t communicate with a helper application. reply:

Tried to implement sample code from session 10131. Running on simulator gives me model loading errors: [Model loading] model loading failed with err -1000 for model path /Users/deszip/Library/Developer/CoreSimulator/Devices/EB928B2D-426F-40DD-A85F-7FF41442C02A/data/Containers/Data/Application/2DC7FE09-4F6E-411F-89CF-E65338EA2101/Library/Spotlight/Resources_V3/Experimental/models/spotlight_l2.mlmodelc and directives path /Users/deszip/Library/Developer/CoreSimulator/Devices/EB928B2D-426F-40DD-A85F-7FF41442C02A/data/Containers/Data/Application/2DC7FE09-4F6E-411F-89CF-E65338EA2101/Library/Spotlight/Resources_V3/Experimental/directives/directives_l2.mdplist And on device looks like smth wrong with xpc to some helper app: ### qid=2 error Error Domain=NSCocoaErrorDomain Code=4097 Couldn’t communicate with a helper application. reply: In general it just does not work :( Any hints or help appreciated.

[/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.
