Have you followed the required steps before opening a bug report?

(Check the step you've followed - put an x character between the square brackets ([]).)

• I have reviewed the documentation in its entirety, including the dedicated documentations 📚.
• I have searched for existing issues and made sure that the problem hasn't already been reported.
• I am using the latest plugin version.

Is the bug specific to iOS or Android? Or can it be reproduced on both platforms?

iOS

Is the bug related to the native implementation? (NSURLSession on iOS and Fetch on Android)

Yes

Environment

Environment:
React native: 0.63.2
react-native-background-downloader: 2.3.4

Target Platform:
iOS (14.0)

Expected Behavior

Simply download the file, exactly how it works on ios simulator

Actual Behavior

The download process runs until 100% and finishes with the following error:
"Download canceled due to error: “CFNetworkDownload_hKBCap.tmp” couldn’t be moved because you don’t have permission to access “87E1D77A-848E-4423-8001-7C3C4A35B6F3”."

Steps to Reproduce

1.Add the library
2.Run the app from xcode to a real device trough usb

This happens to me too. But only on the device but and on simulation true !

iOS - Extra Mandatory Step

In your AppDelegate.m add the following code:

..
#import <RNBackgroundDownloader.h>

...

- (void)application:(UIApplication *)application handleEventsForBackgroundURLSession:(NSString *)identifier completionHandler:(void (^)(void))completionHandler
{
  [RNBackgroundDownloader setCompletionHandlerWithIdentifier:identifier completionHandler:completionHandler];
}

...

Failing to add this code will result in canceled background downloads.

and only use RNBackgroundDownloader.directories.documents for destination.

If it helps, my simulator didnt progress past requesting to download. Had to delete simulator app and reinstall, now working fine.
Device working fine.
