That error is coming out of Core Media, which is part of the video subsystem, and I’ve re-tagged your question accordingly.

I had the same problem. I was because I used the url received in param willDownloadTo of function

urlSession(_:aggregateAssetDownloadTask:willDownloadTo:)

I always received the error -12865

To solve it when download finished in function :

urlSession(_:task:didCompleteWithError:)

I create un bookmarkData with the previous mentioned url, and store it in User defaults with an unique identifier for de asset:

     let userDefaults = UserDefaults.standard
     let bookmark = try downloadURL.bookmarkData()
     userDefaults.set(bookmark, forKey: AssetIdentifier)

With this, when I need the url to playback a recover it from user defaults:

func localAssetFor(withID identifier: String) -> AVURLAsset? { let userDefaults = UserDefaults.standard guard let localFileLocation = userDefaults.value(forKey: identifier) as? Data else { return nil }

    var asset: AVURLAsset?
    var bookmarkDataIsStale = false
    do {
        let url = try URL(resolvingBookmarkData: localFileLocation,
                                bookmarkDataIsStale: &bookmarkDataIsStale)
        if bookmarkDataIsStale {
            fatalError("Bookmark data is stale!")
        }
        
        let urlAsset = AVURLAsset(url: url)
        return urlAsset
    } catch {
        fatalError("Failed to create URL from bookmark with error: \(error)")
    }

}

With this changes I always have to playback offline content without error 12865.

Hope this help

Pedro
