Quick start

You want to show hint view for some UIView.

1. Add to AppDelegate's application(_:didFinishLaunchingWithOptions:) following code:

CTXTutorialEngine.shared.addTutorials { error in
    if let error = error {
        //handle error
    }
}
    
CTXTutorialEngine.shared.start()

1. Add CTXTutorialConfig.json to your project with content:

{
    "tutorials": [
        {
            "id": "0",
            "name": "My view tutorial",
            "events": [
                {
                    "CTXTutorialViewsShownEvent": {
                        "event": {
                            "steps": [
                                {
                                    "text": "Hello world!",
                                    "accessibilityIdentifier": "myView"
                                }
                            ]
                        }
                    }
                }
            ]
        }
    ]
}

And your ViewCotroller's code should looks like this:

import CTXTutorialEngine

class ViewController: CTXTutorialViewController {

    private let myView: UIView = ...
    private let engine = CTXTutorialEngine.shared
    
    override func viewDidLoad() {
        super.viewDidLoad()

        myView.accessibilityIdentifier = "myView"

        view.addSubview(myView)
    }

    override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)

        engine.observe(self, contentType: .dynamic)
    }

    override func viewWillDisappear(_ animated: Bool) {
        super.viewWillDisappear(animated)

        engine.unobserve(self)
    }
}

1. Default Hint View will appear and it will be plain white with black text and gray buttons,

but if you wan to alter appearance you should set parameters of CTXTutorialEngine.shared.appearance. You can do it at app start or on each step of your tutorial by conforming your ViewController to CTXTutorialEngineDelegate:

extension ViewController: CTXTutorialEngineDelegate {

    func engineWillShowTutorialStep(_ engine: CTXTutorialEngine, tutorial: CTXTutorial, with stepInfo: CTXTutorialStepPresentationInfo) {
        let appearance = engine.appearance
        ...
    }
}

and don't forget to set engine.delegate = self in viewDidAppear(_:)
