Synchronously create a UIImage from an UIImagePickerControllerReferenceURL

// Could benefit from some defensive coding :)

import Photos

let url = info[UIImagePickerControllerReferenceURL] as! NSURL
 
let fetchResult = PHAsset.fetchAssetsWithALAssetURLs([url], options: nil)
        
let asset = fetchResult.firstObject as! PHAsset

let manager = PHImageManager.defaultManager()
let options = PHImageRequestOptions()
options.synchronous = true
options.networkAccessAllowed = true

var image: UIImage?

manager.requestImageForAsset(asset,
    targetSize: CGSize(width: 640, height: 640),
    contentMode: .AspectFill,
    options: options,
    resultHandler: {
        (imageResult: UIImage?, properties: [NSObject: AnyObject]?) in

        image = imageResult
})

print(image)
