In swift 4.0 this is how i used fetchAsset() method from Photos framework , to get all videos from photo library.

You can also get the video from specific folder using predicate.

   func fetchAllVideos()
{
    //let albumName = "blah"
    let fetchOptions = PHFetchOptions()
    //        fetchOptions.predicate = NSPredicate(format: "title = %@", albumName)
    //uncomment this if you want video from custom folder
    fetchOptions.predicate = NSPredicate(format: "mediaType = %d ", PHAssetMediaType.video.rawValue )

    let allVideo = PHAsset.fetchAssets(with: .video, options: fetchOptions)
    allVideo.enumerateObjects { (asset, index, bool) in
        // videoAssets.append(asset)
        let imageManager = PHCachingImageManager()
        imageManager.requestAVAsset(forVideo: asset, options: nil, resultHandler: { (asset, audioMix, info) in
            if asset != nil {
                let avasset = asset as! AVURLAsset
                let urlVideo = avasset.url
                print(urlVideo)

            }
        })

    }

}

It will open photo library and only display the movie type content.

#import <MobileCoreServices/MobileCoreServices.h>

UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
imagePicker.mediaTypes = [[NSArray alloc] initWithObjects:(NSString *)kUTTypeMovie, nil];
[self presentModalViewController:imagePicker animated:YES];

Get List of all Video and Thumbnails

Thanks to @Nikhil , who shared info here, it helped me, but still it required couple of hours to make the code executable as he is missing few things in his answer

enter image description here

So I would like to share my full working code

1.just add frameworks AssetsLibrary, AVFoundation and MediaPlayer.

2.AssetBrowserItem.h and AssetBrowserItem.m here

3.use below code to get list of all videos from ios device lib

4.run app and see Log for videos details

#import "HomeViewController.h"
#import <AssetsLibrary/AssetsLibrary.h>
#import <MediaPlayer/MediaPlayer.h>
#import <AVFoundation/AVFoundation.h>
#import "AssetBrowserItem.h"

Checkout the blog post to fetch all video assets using Photos Framework http://iavinashkashyap.blogspot.in/2016/11/get-list-of-all-videos.html

Code:

-(void) getAllVideoAssets{

NSMutableArray *assets = [[NSMutableArray alloc] init];
//Fetch all video assets from Photos
PHFetchResult *assetResults = [PHAsset fetchAssetsWithMediaType:PHAssetMediaTypeVideo options:nil];
//get all assets
for (PHAsset *asset in assetResults){
    NSLog(@"asset type = %zd", asset.mediaType);
    [assets addObject:asset];
}
self.allVideoslistArray = [[NSMutableArray alloc] init];
//create an instance of PHImageManager
PHImageManager *manager = [PHImageManager defaultManager];
for(PHAsset *asset in assets){
    //block of code for represent video assets
    [manager requestAVAssetForVideo:asset options:nil resultHandler:^(AVAsset * _Nullable asset, AVAudioMix * _Nullable audioMix, NSDictionary * _Nullable info) {
        if ([asset isKindOfClass:[AVURLAsset class]]) {
            NSURL *url = (NSURL *)[[(AVURLAsset *)asset URL] fileReferenceURL];
            UIImage *thumbnail = [self createThunbnailImage:url];
            [self.allVideoslistArray addObject:@{@"VideoUrl":url,@"ThumbnailImage":thumbnail, @"VideoAsset":asset}];
        }
    }];
}//end for loop

}

It would be great if you provide Swift 3 version? – Anurag Sharma Apr 26 '17 at 13:05 — Anurag Sharma, Apr 26 '17 at 13:05

Whilst this may theoretically answer the question, [it would be preferable](http://meta.stackexchange.com/q/8259) to include the essential parts of the answer here, and provide the link for reference.

use this method To pick videos From Library.

      //Call this method.
     [self startMediaBrowserFromViewController: self usingDelegate: self];


   - (BOOL) startMediaBrowserFromViewController: (UIViewController*) controller usingDelegate: (id <UIImagePickerControllerDelegate, UINavigationControllerDelegate>) delegate{

       if (([UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypeSavedPhotosAlbum] == NO) || (delegate == nil) || (controller == nil))
           return NO;

       UIImagePickerController *mediaUI = [[UIImagePickerController alloc] init];
       mediaUI.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;

       mediaUI.mediaTypes = [[[NSArray alloc] initWithObjects: (NSString *) kUTTypeMovie, nil] autorelease];
       mediaUI.allowsEditing = YES;
       mediaUI.delegate = self;
       mediaUI.videoMaximumDuration = 60.0;
       //mediaUI.videoQuality = UIImagePickerControllerQualityTypeLow;

       [controller presentModalViewController: mediaUI animated: YES];
       return YES;
