IosModelDownloadDelegate

private class IosModelDownloadDelegate(val destinationPath: String, val onProgress: (Int) -> Unit, val onBytesReceived: (Long) -> Unit, val onComplete: (Result<Unit>) -> Unit) : NSObject, NSURLSessionDownloadDelegateProtocol(source)

NSURLSession delegate that converts native progress callbacks into app download state callbacks.

Author

Parameters

onProgress

Emits integer percent progress when iOS reports total expected byte count.

onBytesReceived

Emits every positive byte delta for traffic statistics.

onComplete

Completes the callbackFlow with success or a user-visible download error.
