How to use

[ximlu]

I have followed the documentation to use it in my project, but the callback has not been captured. I'm not sure if it's a bug or an issue with my implementation. It would be great if there is a demo on how to upload and download data.

@ximlu Please check out @thillsman's project for an example (specifically look at KnapsackManager.swift). Also pay attention to what is getting logged with subsystem "com.ryanashcraft.CloudSyncSession"

I tried according to the configuration, but kept reporting errors. The following is the log of the project output

[ximlu]

I created a RecordType using my own account, and used the public_database as I wanted to check whether the data was successfully synced on the CloudKit dashboard. However, I have been receiving errors and am not quite sure where the problem lies. Here is a configuration:

static let storeIdentifier: String = "xxxxxxxxx"
static let zoneID: CKRecordZone.ID = .default
static let subscriptionID: String = ""
static let log: OSLog = .default

[ximlu]

I can basically confirm that there is indeed a problem with the framework, and I can upload it using the original API

[ryanashcraft]

@ximlu I am not sure. I can tell you that this framework has been used in production for my app. There is likely something environmental causing issues. Are you testing this on a simulator or an actual device? The error seems to be underlying in the CloudKit framework itself, and CloudSyncSession is halting as a result.

Have you tried setting subscriptionID to something that's not empty string?

[ximlu]

@ryanashcraft I am using real device for testing, and the system is iOS16+. Therefore, I really hope that you can provide a demo without any issues. I highly doubt the reliability of the demo you mentioned for self-use.
