Hi, just fresh beginner with sceneKit, I got a problem I can't understand nor work around ... the idea: a lunar module "Eagle" landing on the Moon. A camera and a spotlight are supposed to track it. All nodes have been created in a scene with the scene editor and/or directly coded from SCN routines. the code: camera = sceneView.scene!.rootNode.childNodes.filter({ $0.name == "theCamera" }).first! //-> got it theEagle = sceneView.scene!.rootNode.childNodes.filter({ $0.name == "Eagle2" }).first! //- got it too spotLight = sceneView.scene!.rootNode.childNodes.filter({ $0.name == "theSpotLight" }).first! // done. ... then the constraints: let cameraLookAtTheEagle = SCNLookAtConstraint(target: theEagle) let spotLookAtTheEagle = SCNLookAtConstraint(target: theEagle) let cameraLookAtTheEagle.isGimbalLockEnabled = true let spotLookAtTheEagle.isGimbalLockEnabled = true let camera.constraints    = [cameraLookAtTheEagle] let spotLight.constraints = [spotLookAtTheEagle] ... The problem is: when my Eagle starts moving up and down, it is perfectly tracked by the spot, but ignored by the camera ... and of course gets quickly out of the field. I tried to use one only constraint for both of them: same result I tried to implement the constraints with the scene editor: same result I tried to implement the camera and the spot directly in the code: same result tried to set the isGimbalLockEnabled = false: same result I even try to change the order of the actions on spot and camera ... same result Whatever I tried, the camera refuses to move a inch ... So where's the problem ? Why does the spot always do the job, and why doesn't the camera do it? Any advice or clue will be welcome like fresh water in the desert ... Thanks.

Hello, I simply tried the statement var a = 🙉 in a new iPhone/iPad Swift Project, and I get the error from the Xcode text editor: "cannot find 🙉 in scope" I suppose there is an option somewhere in the Project parameters which enables emojis ... but where ? thank's for any clue!
