How to get a random image using ARKit framework?

func view(_ view: ARSKView, nodeFor anchor: ARAnchor) -> SKNode? // Create and configure a node for the anchor added to the view's session. let arrayOfImages = ["Photo1", "Photo2", "Photo3", "Photo4", "Photo5", "Photo6", "Photo7", "Photo8", "Photo9", "Photo10", "Photo11", "Photo12", "Photo13", "Photo14", "Photo15", "Photo16", "Photo17", "Photo18", "Photo19", "Photo20", "Photo21", "Photo22", "Photo23", "Photo24", "Photo25", "Photo26", "Photo27", "Photo28", "Photo29", "Photo30"] let node = SKSpriteNode(imageNamed: (arc4random() % UInt32 (arrayOfImages.count)) ) return node;

But it says an error saying it:

//Can't convert value of type `UIImage` to expected argument type string.

Try this code:

let arrayOfImages = ["Photo1", "Photo2", "Photo3", "Photo4", "Photo5", "Photo6", "Photo7", "Photo8", "Photo9", "Photo10", "Photo11", "Photo12", "Photo13", "Photo14", "Photo15", "Photo16", "Photo17", "Photo18", "Photo19", "Photo20", "Photo21", "Photo22", "Photo23", "Photo24", "Photo25", "Photo26", "Photo27", "Photo28", "Photo29", "Photo30"] let randomIndex = Int(arc4random_uniform(UInt32(arrayOfImages.count))) let Image = UIImage(named: arrayOfImages[randomIndex]) let Texture = SKTexture(image: Image) let Sprite = SKSpriteNode(texture:Texture)

Thanks but this didn't work it now says, Cannot convert value of type UInt32 to expect argument type string. If you have any other suggestions I would be happy to hear them

Thanks for that the array is working now, but I have another problem. In the same phrase when I return the node it says "Error Expected declaration." This is the code I would be very grateful if you could help me out. Thanks a lot Ben "func view(_ view: ARSKView, nodeFor anchor: ARAnchor) -> SKNode? \Code ;return node; ERROR Expected declaration"
