SceneView hittest crash on ios 11.4, runs on iOS 12+
I am experiencing a crash of the m_sceneView.hittest(...) function on iOS 11.4. The same code runs on iOS 12+ !
Code looks like this:
func renderer(_ renderer: SCNSceneRenderer, updateAtTime time: TimeInterval) {
guard m_sceneView.session.currentFrame != nil else {return}
DispatchQueue.main.async(execute: {
if let camera = self.m_sceneView.session.currentFrame?.camera,
case .normal = camera.trackingState {
let results = self.m_sceneView.hitTest(self.m_sceneView.center,
options: [SCNHitTestOption.searchMode: 2])
guard let result = results.first else {
print("No Hittest results received")
return
}
// do something with the hittest result !
// ...
// ...
}
})
}
I get a "EXC_BAD_ACCESS (code=1, address=0x0)" crash on the hittest line.
- I have checked that the self.m_sceneView.center contains valid values
- I am checking for the session state (as you see in the code)
- The problem is reproducible.
- The view I am operating on is an ARSCNView
Any ideas how to fix this issue ?

I got a Solution from Apple guys. It is actually a bug in the SceneKit API which was solved in IOS 12, but there is a workaround for versions earlier than 12:
let options: [SCNHitTestOption: Any] = [SCNHitTestOption.boundingBoxOnly: true]
let hitResults = scnView.hitTest(p, options: options)
