Tap / Select Node in SceneKit (Swift)

Question

I'm new to SceneKit and 3D spaces in iOS. I'm currently working on a simple game that shows a cube of 28 segments ("mini cubes" if you want).

I want to move the mini cubes by tapping them, but I can't get my head around how to select specific nodes (childnodes of the big cube).

Can anybody help me or post a link to SceneKit tutorials for dummies? I've been looking for days now, and haven't found what I'm looking for.

Cheers

You can hit test the scene view (for example from the location of a tap gesture recognizer), which will give you a list of hit test results. From each result you can get the node (and other information):

let location: CGPoint = // for example from a tap gesture recognizer
let hits = self.sceneView.hitTest(location, options: nil)
if let tappedNode = hits?.first?.node {
    // do something with the tapped node ...
}
