github "tilltue/TLPhotoPicker"

Don't forget the Privacy Description in info.plist.

Usage

use delegate & custom cell

class ViewController: UIViewController,TLPhotosPickerViewControllerDelegate {
    var selectedAssets = [TLPHAsset]()
    @IBAction func pickerButtonTap() {
        let viewController = TLPhotosPickerViewController()
        viewController.delegate = self
        var configure = TLPhotosPickerConfigure()
        //configure.nibSet = (nibName: "CustomCell_Instagram", bundle: Bundle.main) // If you want use your custom cell..
        self.present(viewController, animated: true, completion: nil)
    }
    //TLPhotosPickerViewControllerDelegate
    func dismissPhotoPicker(withTLPHAssets: [TLPHAsset]) {
        // use selected order, fullresolution image
        self.selectedAssets = withTLPHAssets
    }
    func dismissPhotoPicker(withPHAssets: [PHAsset]) {
        // if you want to used phasset. 
    }
    func photoPickerDidCancel() {
        // cancel
    }
    func dismissComplete() {
        // picker viewcontroller dismiss completion
    }
    func didExceedMaximumNumberOfSelection(picker: TLPhotosPickerViewController) {
        // exceed max selection
    }
    func handleNoAlbumPermissions(picker: TLPhotosPickerViewController) {
        // handle denied albums permissions case
    }
    func handleNoCameraPermissions(picker: TLPhotosPickerViewController) {
        // handle denied camera permissions case
    }
}

//Custom Cell must subclass TLPhotoCollectionViewCell

class CustomCell_Instagram: TLPhotoCollectionViewCell {

}

//If you want custom camera cell?
//only used camera cell

        viewController.handleNoCameraPermissions = { [weak self] (picker) in
            // handle denied camera permissions case
        }
        viewController.selectedAssets = self.selectedAssets
        self.present(viewController, animated: true, completion: nil)
    }
}

TLPHAsset

public struct TLPHAsset {
    public enum AssetType {
        case photo,video,livePhoto
    }
    // phasset 
    public var phAsset: PHAsset? = nil
    // selected order index
    public var selectedOrder: Int = 0
    // asset type
    public var type: AssetType
    // get full resolution image 
    public var fullResolutionImage: UIImage?
    // get photo file size (async)
    public func photoSize(options: PHImageRequestOptions? = nil ,completion: @escaping ((Int)->Void), livePhotoVideoSize: Bool = false)
    // get video file size (async)
    public func videoSize(options: PHVideoRequestOptions? = nil, completion: @escaping ((Int)->Void))
    // get async icloud image (download)
    @discardableResult
    public func cloudImageDownload(progressBlock: @escaping (Double) -> Void, completionBlock:@escaping (UIImage?)-> Void ) -> PHImageRequestID?
    // get original media file async copy temporary media file ( photo(png,gif...etc.) and video ) -> Don't forget, You should delete temporary file.
    // parmeter : convertLivePhotosToPNG
    // false : If you want mov file at live photos
    // true  : If you want png file at live photos ( HEIC )
    public func tempCopyMediaFile(videoRequestOptions: PHVideoRequestOptions? = nil, imageRequestOptions: PHImageRequestOptions? = nil, exportPreset: String = AVAssetExportPresetHighestQuality, convertLivePhotosToJPG: Bool = false, progressBlock:((Double) -> Void)? = nil, completionBlock:@escaping ((URL,String) -> Void)) -> PHImageRequestID?
    //Apparently, this method is not be safety to export a video.
    //There is many way that export a video.
    //This method was one of them.
    public func exportVideoFile(options: PHVideoRequestOptions? = nil, progressBlock:((Float) -> Void)? = nil, completionBlock:@escaping ((URL,String) -> Void))
    // get original asset file name
    public var originalFileName: String?
}

Note: convenience export method fullResolutionImage, cloudImageDownload, tempCopyMediaFile, exportVideoFile It's not enough if you wanted to use more complicated export asset options. ( progress, export type, etc..)
