}
It is saved in this path:
"Users/devendrasingh/Library/Developer/CoreSimulator/Devices/394AD1C9-E950-422E-BDA1-083CDCEE83F6/data/Containers/Data/Application/98BEC162-C686-4BC1-B698-567B45D65F27/Documents/exportFinal.mov
"
It's not saving in camera roll

Try this:
[[[ALAssetsLibrary alloc] init] writeVideoAtPathToSavedPhotosAlbum:outputFileURL completionBlock:^(NSURL *assetURL, NSError *error) {
if (error)
NSLog(#"%#", error);
[[NSFileManager defaultManager] removeItemAtURL:outputFileURL error:nil];
}];
