I think this question could be merged with this one Screenshotting on Iphone in swift only has a white background

which seems the same

EDIT:

I think I found a solution. First read this post: How Do I Take a Screen Shot of a UIView?

I create an Extensions.swift file in which I 'extended' the methods of a UIView using that link.

After that I simply connect the following to my sprite-kit button

let screenshot = self.view?.pb_takeSnapshot()
UIImageWriteToSavedPhotosAlbum(screenshot, nil, nil, nil)

Voilà, the image is in the camera roll!

Here is how I solved it in swift 3: This captures all the nodes in your scene: Note: in below code represents the view it is capturing from. You may want to update it with your view in project.

func captureScreen() -> UIImage {
    UIGraphicsBeginImageContextWithOptions(yourview.bounds.size, true, 0)

    yourview.drawHierarchy(in: yourview.bounds, afterScreenUpdates: true)


    let image = UIGraphicsGetImageFromCurrentImageContext()!
    UIGraphicsEndImageContext()
    return image
}
