Creating UIImage with renderingMode in Swift

Question

In objectiveC I would do this

UIImage *image = [[UIImage imageNamed:@"myImage.png"]   imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

but in Swift I have tried all alternatives like this, without success

var image : UIImage = UIImage(named:"myImage.png").imageWithRenderingMode(renderingMode: AlwaysOriginal)

It shows an error: use of unresolved identifier 'AlwaysOriginal'

How do I do that?

that would be the proper syntax:

(for Swift 3.x or Swift 4)

var image: UIImage? = UIImage(named:"myImage")?.withRenderingMode(.alwaysOriginal)

(for Swift 2.x)

var image: UIImage? = UIImage(named:"myImage.png").imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal)

but you can use this 'shortcut' as well:

var image: UIImage? = UIImage(named:"myImage.png").imageWithRenderingMode(.AlwaysOriginal)

ahhh, fantastic. You pass a kind of object that has a enum value. I thought I just needed to pass the enum value. THANKS!

uggh, I wish Xcode's code complete would be just a bit smarter, e.g. if you type ".imageWithRenderingMode" it really should predict ".withRenderingMode"...would save countless google searches
