WWCD2019のセッション204を再現しての話 ? すべてが解決しました
解決方法は ? 解決できなかったのは私がSwiftUIについて無知であったから ?
しかし、解決しました、良かった、良かった
少し解説 ?
- Roomsで実機やsimulatorで作動させるためには ? SceneDelegate.swiftに秘密がありました
- 私は「let contentView = ContentView()」で呼んでいた
- 苦心の結果 ? 「let contentView = ContentView(store: RoomStore(rooms: testData))」で呼んであげればOKです
コードを見た方が早い ?
能書きはここまで、以下コード
SceneDelegate.swift

import UIKit
import SwiftUI
class SceneDelegate: UIResponder, UIWindowSceneDelegate {
var window: UIWindow?
func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
// Use this method to optionally configure and attach the UIWindow `window` to the provided UIWindowScene `scene`.
// If using a storyboard, the `window` property will automatically be initialized and attached to the scene.
// This delegate does not imply the connecting scene or session are new (see `application:configurationForConnectingSceneSession` instead).
// Create the SwiftUI view that provides the window contents.
//let contentView = ContentView()
let contentView = ContentView(store: RoomStore(rooms: testData))
// Use a UIHostingController as window root view controller.
if let windowScene = scene as? UIWindowScene {
let window = UIWindow(windowScene: windowScene)
window.rootViewController = UIHostingController(rootView: contentView)
self.window = window
window.makeKeyAndVisible()
}
}
func sceneDidDisconnect(_ scene: UIScene) {
// Called as the scene is being released by the system.
// This occurs shortly after the scene enters the background, or when its session is discarded.
// Release any resources associated with this scene that can be re-created the next time the scene connects.
// The scene may re-connect later, as its session was not neccessarily discarded (see `application:didDiscardSceneSessions` instead).
}
func sceneDidBecomeActive(_ scene: UIScene) {
// Called when the scene has moved from an inactive state to an active state.
// Use this method to restart any tasks that were paused (or not yet started) when the scene was inactive.
}
func sceneWillResignActive(_ scene: UIScene) {
// Called when the scene will move from an active state to an inactive state.
// This may occur due to temporary interruptions (ex. an incoming phone call).
}
func sceneWillEnterForeground(_ scene: UIScene) {
// Called as the scene transitions from the background to the foreground.
// Use this method to undo the changes made on entering the background.
}
func sceneDidEnterBackground(_ scene: UIScene) {
// Called as the scene transitions from the foreground to the background.
// Use this method to save data, release shared resources, and store enough scene-specific state information
// to restore the scene back to its current state.
}
}
ここまで
私の感想
私の感想ですが ?
なんだかね ? Appleの動画にその部分があったのかね ? 私が見落としをしていたのか ? いや違う ? 私が無知なだけでした、SwiftUIのCanvasはこれから勉強を深めたいと思います
