[Tips]SwiftUI側でViewControllerを表示

このはじめに

SwiftUIからViewControllerを表示する時のTipsです。

ViewControllerとStoryboard

記事用に作成したViewControllerとStoryboardになります。

ViewController

SampleViewController.swift

import UIKit
import Instantiate
import InstantiateStandard

class SampleViewController: UIViewController, StoryboardInstantiatable {

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

Storyboard

UIViewControllerRepresentableを使用

SampleViewController.swift

import UIKit
import SwiftUI
import Instantiate
import InstantiateStandard

class SampleViewController: UIViewController, StoryboardInstantiatable {

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

struct SampleViewControllerWrapper : UIViewControllerRepresentable {

    typealias UIViewControllerType = SampleViewController

    func makeUIViewController(context: UIViewControllerRepresentableContext<SampleViewControllerWrapper>) -> SampleViewControllerWrapper.UIViewControllerType {
        return UIViewControllerType.instantiate()
    }

    func updateUIViewController(_ uiViewController: SampleViewControllerWrapper.UIViewControllerType, context: UIViewControllerRepresentableContext<SampleViewControllerWrapper>) {
    }
}

SwiftUIからSampleViewControllerを表示する

SampleView.swift

import SwiftUI

struct SampleView: View {
    var body: some View {
        SampleViewControllerWrapper()
    }
}

#if DEBUG
struct SampleView_Previews: PreviewProvider {
    static var previews: some View {
        SampleView()
    }
}
#endif
