SwiftUI

The SDK can be integrated into a SwiftUI project with the following steps.

Steps

Create a view controller that will host the SDK
Create a UIViewControllerRepresentable
Create a SwiftUI view to place the UIViewControllerRepresentable inside
Place SDKView in the SwiftUI View you want to launch the SDK From

Create a view controller that will host the SDK

This is your view controller from which the SDK will be presented. It will also act as the SDK delegate.

import UIKit
import CarTrawlerSDK

class SDKHostViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
    }
}

extension SDKHostViewController: CarTrawlerSDKDelegate {
    func didProduce(inPathPaymentRequest request: [AnyHashable: Any], vehicle: CTInPathVehicle, payment: Payment) {
    }
    func didReceive(_ reservationDetails: CTReservationDetails) {
    }
}

Create a UIViewControllerRepresentable

This is needed to use the host controller in our SwiftUI code.

struct SDKHostVCRepresentable: UIViewControllerRepresentable {
    func updateUIViewController(_ uiViewController: UIViewControllerType, context: Context) {
    }

    func makeUIViewController(context: Context) -> some UIViewController {
      let hostingController = SDKHostViewController()
      let context = CTContext(implementationID: "your implementation ID", 
                              clientID: "your client ID", 
                              flow: .standAlone)
      let defaults = UserDefaults.standard
      let language = "en"

      context.countryCode = "IE" // The country code associated with the device’s system region is used by default.
      context.currencyCode = "EUR" // The currency associated with the device’s system region is used by default.
      context.languageCode = language == "no" ? "nb" : language // The language associated with the device’s system region is used by default.

      context.delegate = hostingController
      CarTrawlerSDK.sharedInstance().present(from: hostingController, context: context)

      return hostingController
  }
}

Create a SwiftUI view to place the UIViewControllerRepresentable inside

struct SDKView: View {
    var closeAction: (() -> Void) = {}
    var body: some View {
        ZStack {
            SDKHostVCRepresentable()
        }.onDisappear(perform: self.closeAction)
    }
}

Place SDKView in the SwiftUI View you want to launch the SDK From

You can place the SDKView inside a ZStack along with the button your user will tap to launch the SDK.

import SwiftUI

struct TestView: View {
    
    @State private var showSDK = false
    
    var body: some View {
        ZStack {
            
            if showSDK {
                SDKView(closeAction: {
                    withAnimation(.easeOut(duration: 0.25)) { self.showSDK = false }
                }).transition(.identity)
            }
            
            VStack() {
                Spacer()
                Button("Show SDK") {
                    self.showSDK = true
                }
                Spacer()
            }
            .padding()
        }
    }
}
