How to capture multi images as Data/PHAsset/UIImage and display it

1. Create your pod file and install :

    pod 'BSImagePicker'
   

2. in Info.plist add :

    NSPhotoLibraryUsageDescription
   

3. Create your design with collectionView to appear image on ot.

4. In ViewController Define vars like you want like this :

    var myImages:[Data]! = [Data]() 
   
    var SelectedAssets = [PHAsset]() 
   
    var photoArray = [UIImage]() 
   

5. For call method to open image

    func openPhoto() {
    
    let imagePicker = ImagePickerController()
    
    presentImagePicker(imagePicker, select: { (asset) in
   
    }, deselect: { (asset) in
    
    }, cancel: { (assets) in
   
    }, finish: { (assets) in
   
    for i in 0..<assets.count {
        self.SelectedAssets.append(assets[i])
    }
        self.convertAssetsToImages()
    })
   

   }

6. If you want to convertvAssetsvTo Images use method such as :

    func convertAssetsToImages() -> Void {
   
    if SelectedAssets.count != 0 {
    
     self.myImages.removeAll()
     self.photoArray.removeAll()
    
     for i in 0..<SelectedAssets.count {
        
        let manager = PHImageManager.default()
        let option = PHImageRequestOptions()
        var thumbnail = UIImage()
        option.isSynchronous = true
        manager.requestImage(for: SelectedAssets[i], targetSize: CGSize(width: 200, height: 200), contentMode: PHImageContentMode.aspectFill, options: option, resultHandler: { (result, info) -> Void in
            thumbnail = result!
        })
        
        let data = thumbnail.jpegData(compressionQuality: 0.7)
        let newImage = UIImage(data: data!)
        self.photoArray.append(newImage! as UIImage)
   
        self.myImages.append(data!)
        
        }
    
        DispatchQueue.main.async {
          self.collectionView.reloadData()
        }
    
    }
        
    }
