PHAsset to UIImage

Question

I\'m attempting to create a UIImage (like a thumbnail or something) from a PHAsset so that I can pass it into something that takes a UIImage. I\'ve tried adapting solutions

Answer 1

Swift 4.

resizeMode,deliveryMode - These can be set according to user requirement.

isNetworkAccessAllowed - set this to "true" for fetching images from the cloud

imageSize- required image size

func getImageFromAsset(asset:PHAsset,imageSize:CGSize, callback:@escaping (_ result:UIImage) -> Void) -> Void{

    let requestOptions = PHImageRequestOptions()
    requestOptions.resizeMode = PHImageRequestOptionsResizeMode.fast
    requestOptions.deliveryMode = PHImageRequestOptionsDeliveryMode.highQualityFormat
    requestOptions.isNetworkAccessAllowed = true
    requestOptions.isSynchronous = true
    PHImageManager.default().requestImage(for: asset, targetSize: imageSize, contentMode: PHImageContentMode.default, options: requestOptions, resultHandler: { (currentImage, info) in
        callback(currentImage!)
    })
}
