To Reproduce
Steps to reproduce the behavior:

required public init() {
    fatalError("init() has not been implemented")
}

this occurs an error “Thread 1: Fatal error: init(coder:) has not been implemented”

Expected behavior

shouldn't it be changed to like below?

required public init?(coder decoder: NSCoder){
fatalError("init(coder:) has not been implemented")
}

Screenshots
If applicable, add screenshots to help explain your problem.

Environment:

• iOS Version : 15.6
• Device Information : iPad Pro(12.9)(4th)
• macOS Version : 13.1
• Xcode Version : 14.2

Additional context

[maxxfrazer]

the intention is that the empty initialiser shouldn't be used, instead when created the focusentity should already have a reference to the ARView:

Thank you for your reply.
I'm a beggnier and testing a sample code referring to 'https://youtu.be/9R_G0EI-UoI'

I wrote like below and the whole code were builded successfully.

class CustomARView: ARView{
let focusSquare = FocusEntity()
required init(frame frameRect: CGRect) {
super.init(frame: frameRect)
focusSquare.viewDelegate = self
focusSquare.delegate = self
focusSquare.setAutoUpdate(to: true)
self.setupARView()
}
required init?(coder decoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
func setupARView(){
let config = ARWorldTrackingConfiguration()
config.planeDetection = [.horizontal, .vertical]
config.environmentTexturing = .automatic
if ARWorldTrackingConfiguration.supportsSceneReconstruction(.mesh){
config.sceneReconstruction = .mesh
}
self.session.run(config)
}
}

Nevertheless the error, Thread 1: Fatal error: init() has not been implemented, occurred on FocusEntity.swift's line 288.

It would be grateful if you could help me with this problem.

Hi, I remember in Ryan's video (the one you linked), he does specify that he's using a specific package version, which is older than the current latest version of 2.3.0

Check out the example which is included in this repo for up-to-date usage, otherwise make sure you're using the same version as in the video.

Thank you Maxx, I've imported the same version of package and builded successfully. However I cannot see a square focus on my ipad.
in this case, which part should I look into? (the init works.)

Ryan runs through the additional steps after initialisation in his video.
I’d recommend just cloning this repository and taking a look at the example project, which contains a working example with a few changeable parameters.
