This download manager uses NSURLSession api to download files. It can download multiple files at a time. It can download large files if app is in background. It can resume downloads if app was quit.
I have been getting crash report. I am seeing it on iOS 11 with iPhone 8. i also found when app coming from background to foreground its crashing in iOS 10.
