Summary:
When requesting data for a PHAssetResource, the request fails at 50% and reports the following error:
2017-02-17 16:20:23.649561 MyApp[12063:5383858] Error: Unable to locate resource <PHInternalAssetResource: 0x1702f1b80> type=video size={1920, 1080} fileSize=43806718 uti=com.apple.quicktime-movie filename=IMG_2972.MOV assetLocalIdentifier=60A58560-728D-4DC3-83C5-4C75D27C2421/L0/001
If I immediately retry the same request, it succeeds. The "download" is also much faster the second time, suggesting that the asset is indeed getting fetched and cached despite the reported failure.
Steps to Reproduce:
1) Request data for a PHAssetResource using PHAssetResourceManager.requestData(for: resource, options: options, dataReceivedHandler: {...}, completion: {...}).
Expected Results:
Data for the resource is fetched, and the completion handler returns a nil error.
Actual Results:
When the request's progress reaches 50%, the completion handler is called with the following error:
Error Domain=NSCocoaErrorDomain Code=-1 "(null)"
The "Unable to locate resource" error given above is shown in the Xcode console.
Version:
iOS 10.2.1 (14D27)
Notes:
The same behavior can be seen when using PHAssetResourceManager.writeData(for: assetResource, ...).
