SceneKit Scene Background Contents UIImage Array Error

Question

I am developing a game for iOS using SceneKit . When I want to set a skybox to the scene I get an error:

var path = "skyboxes.scnassets/skybox"
self.scene!.background.contents = [
        UIImage(named: path+"_right.png"),
        UIImage(named: path+"_left.png"),
        UIImage(named: path+"_top.png"),
        UIImage(named: path+"_bottom.png"),
        UIImage(named: path+"_front.png"),
        UIImage(named: path+"_back.png"),
    ]

Error: Cannot assign a value of type [UIImage?] to a value of type AnyObject!

I tried to cast the array to a NSArray or an AnyObject array but that doesn't work.

Could anyone help me?

Answer 1

contents is of type [AnyObject!] ; so, the following should work:

scene!.background.contents =
[
    UIImage(named: path+"_right.png") as UIImage!              
    UIImage(named: path+"_left.png") as UIImage!,
    UIImage(named: path+"_top.png") as UIImage!,
    UIImage(named: path+"_bottom.png") as UIImage!,
    UIImage(named: path+"_front.png") as UIImage!,
    UIImage(named: path+"_back.png") as UIImage!,
]
