In your Application, you don't have permission to access the file of /var/mobile/Media/DCIM/100APPLE/IMG_0048.JPG, because of Sandboxing.

So, whatever you do, you can't initialize NSData or UIImage with the file path. But you can access the file of /var/mobile/Media/DCIM/100APPLE/xxx.mov with AVURLAsset. In my application, I extracted the data rather than URL from gallery by Photos kit and initialized UIImage with the data.

PHImageManager.default().requestImageData(
    for: assetObject!, options: options,
    resultHandler: {
        data, _, _, _ in
        if data != nil {
            self.assetUrl = movieMaker.createMovieFrom(imageData: data!, duration: Int(CXPreparetValue.imageDuration))
        }
})

it works for me! If you have other opinions, please tell me.
