How to integrate Strada?

[sevos]

I am struggling integrating TurboNavigator with Strada.

Strada quick start advises to implement such version of VisitableViewController:

class TurboWebViewController: VisitableViewController, BridgeDestination {

    private lazy var bridgeDelegate: BridgeDelegate = {
        BridgeDelegate(location: visitableURL.absoluteString,
                       destination: self,
                       componentTypes: BridgeComponent.allTypes)
    }()

    // MARK: View lifecycle

    override func viewDidLoad() {
        super.viewDidLoad()
        bridgeDelegate.onViewDidLoad()
    }

    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
        bridgeDelegate.onViewWillAppear()
    }

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

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

    override func viewDidDisappear(_ animated: Bool) {
        super.viewDidDisappear(animated)
        bridgeDelegate.onViewDidDisappear()
    }

    // MARK: Visitable

    override func visitableDidActivateWebView(_ webView: WKWebView) {
        bridgeDelegate.webViewDidBecomeActive(webView)
    }

    override func visitableDidDeactivateWebView() {
        bridgeDelegate.webViewDidBecomeDeactivated()
    }
}

I figured out the private method TurboNavigator#controller (sorry for ruby'ish method digests!) is responsible for the instantiation of VisitableViewController. I've tried to extend TurboNavigator or inherit from it, but the current visibility modifiers forbits such attempts.

extension TurboNavigator {
    private func controller(for proposal: VisitProposal) -> UIViewController? {
        switch delegate.handle(proposal: proposal) {
        case .accept:
            return VisitableViewController(url: proposal.url)
        case .acceptCustom(let customViewController):
            return customViewController
        case .reject:
            return nil
        }
    }
}

The code above complains that delegate is private.

How would you approach this?

This part of the README should guide you in the right direction. https://github.com/joemasilotti/TurboNavigator

1. Set the delegate of Turbo Navigator
2. Implement the function to return your controller

It's probably also worth to mention here: https://masilotti.com/strada-and-turbo-navigator/

Thanks @marcoroth! This issue prompted that post and I totally forgot to link to it.

@sevos, have you gotten it to work?

Hey @joemasilotti - Thank you so much! It works! :)

One thing that might be worth adjusting in the article would be to include "Turbo Native" string in the user agent:

        TurboConfig.shared.userAgent += "Turbo Native \(Strada.userAgentSubstring(for: BridgeComponent.allTypes))"

It's common to use turbo_native_app? helper in Rails and it reacts to this substring

EDIT: I see, you are just appending there, got confused, sorry!

Awesome, glad it was helpful!
