I am trying to create a share sheet to share a Text, it was working fine in iOS 14 but in iOS 15 it tells me that
'windows' was deprecated in iOS 15.0: Use UIWindowScene.windows on a
relevant window scene instead.
how can I make it work on iOS 15 with SwiftUI
Button {
let TextoCompartido = "Hola 😀 "
let AV = UIActivityViewController(activityItems: [TextoCompartido], applicationActivities: nil)
UIApplication.shared.windows.first?.rootViewController?.present(AV, animated: true, completion: nil)
}
I think you would be best served using SwiftUI APIs directly. Generally, I would follow these steps.
Create SwiftUI View named ActivityView that adheres to UIViewControllerRepresentable. This will allow you to bring UIActivityViewController to SwiftUI.
Create an Identifiable struct to contain the text you'd like to display in the ActivityView. Making this type will allow you to use the SwiftUI sheet API and leverage SwiftUI state to tell the app when a new ActivityView to be shown.
Create an optional #State variable that will hold on to your Identifiable text construct. When this variable changes, the sheet API will perform the callback.
When the button is tapped, update the state of the variable set in step 3.
Use the sheet API to create an ActivityView which will be presented to your user.
The code below should help get you started.
import UIKit
import SwiftUI
// 1. Activity View
struct ActivityView: UIViewControllerRepresentable {
let text: String
func makeUIViewController(context: UIViewControllerRepresentableContext<ActivityView>) -> UIActivityViewController {
return UIActivityViewController(activityItems: [text], applicationActivities: nil)
}
func updateUIViewController(_ uiViewController: UIActivityViewController, context: UIViewControllerRepresentableContext<ActivityView>) {}
}
// 2. Share Text
struct ShareText: Identifiable {
let id = UUID()
let text: String
}
struct ContentView: View {
// 3. Share Text State
#State var shareText: ShareText?
var body: some View {
VStack {
Button("Show Activity View") {
// 4. New Identifiable Share Text
shareText = ShareText(text: "Hola 😀")
}
.padding()
}
// 5. Sheet to display Share Text
.sheet(item: $shareText) { shareText in
ActivityView(text: shareText.text)
}
}
}
For the future, iOS 16 will have the ShareLink view which works like this:
Gallery(...)
.toolbar {
ShareLink(item: image, preview: SharePreview("Birthday Effects"))
}
Source: https://developer.apple.com/videos/play/wwdc2022/10052/
Time code offset: 25 minutes 28 seconds
To avoid warning, change the way you retrieve the window scene.
Do the following:
Button {
let TextoCompartido = "Hola 😀 "
let AV = UIActivityViewController(activityItems: [TextoCompartido], applicationActivities: nil)
let scenes = UIApplication.shared.connectedScenes
let windowScene = scenes.first as? UIWindowScene
windowScene?.keyWindow?.rootViewController?.present(AV, animated: true, completion: nil)
}
Tested in in iOS 15 with SwiftUI
func shareViaActionSheet() {
if vedioData.vedioURL != nil {
let activityVC = UIActivityViewController(activityItems: [vedioData.vedioURL as Any], applicationActivities: nil)
UIApplication.shared.currentUIWindow()?.rootViewController?.present(activityVC, animated: true, completion: nil)
}
}
To avoid iOS 15 method deprecation warning use this extension
public extension UIApplication {
func currentUIWindow() -> UIWindow? {
let connectedScenes = UIApplication.shared.connectedScenes
.filter { $0.activationState == .foregroundActive }
.compactMap { $0 as? UIWindowScene }
let window = connectedScenes.first?
.windows
.first { $0.isKeyWindow }
return window
}
}
you could try the following using the answer from: How to get rid of message " 'windows' was deprecated in iOS 15.0: Use UIWindowScene.windows on a relevant window scene instead" with AdMob banner?
Note that your code works for me, but the compiler give the deprecation warning.
public extension UIApplication {
func currentUIWindow() -> UIWindow? {
let connectedScenes = UIApplication.shared.connectedScenes
.filter({
$0.activationState == .foregroundActive})
.compactMap({$0 as? UIWindowScene})
let window = connectedScenes.first?
.windows
.first { $0.isKeyWindow }
return window
}
}
struct ContentView: View {
let TextoCompartido = "Hola 😀 "
var body: some View {
Button(action: {
let AV = UIActivityViewController(activityItems: [TextoCompartido], applicationActivities: nil)
UIApplication.shared.currentUIWindow()?.rootViewController?.present(AV, animated: true, completion: nil)
// This works for me, but the compiler give the deprecation warning
// UIApplication.shared.windows.first?.rootViewController?.present(AV, animated: true, completion: nil)
}) {
Text("Hola click me")
}
}
}
I am working on implementing Interstitial ads in my app and running into some confusion with the docs provided by Admob and the new SwiftUI app structure.
Here is the app.swift file, showing that I've implemented the GoogleMobileAds and started it in the didFinishLaunchingWithOptions method.
import SwiftUI
import GoogleMobileAds
#main
struct adamsCalcApp: App {
var calculator = Calculator()
#UIApplicationDelegateAdaptor(AppDelegate.self) var appDelegate
var body: some Scene {
WindowGroup {
ContentView().environmentObject(calculator)
}
}
}
class AppDelegate: NSObject, UIApplicationDelegate {
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
// Setup google admob instance
GADMobileAds.sharedInstance().start(completionHandler: nil)
return true
}
}
In my ContentView.swift File, I have the interstitial variable created like...
#State var interstitial: GADInterstitialAd?
Then on the main stack in the view, I call onAppear(perform: ) to load the ad, however I keep getting this error.
.onAppear(perform: {
let request = GADRequest()
GADInterstitialAd.load(withAdUnitID:"ca-app-pub-3940256099942544/4411468910",
request: request,
completionHandler: { [self] ad, error in
if let error = error {
return
}
interstitial = ad
interstitial?.fullScreenContentDelegate = self
}
)
})
"Cannot assign value of type 'ContentView' to type
'GADFullScreenContentDelegate?'"
I am feeling a bit clueless after trying a few different workarounds and trying to look up a setup that is like mine, AdMob docs still show how to implement with class ViewControllers and I would like to figure out how to do this is SwiftUI.
import SwiftUI
import GoogleMobileAds
import AppTrackingTransparency
import AdSupport
class AdsManager: NSObject, ObservableObject {
private struct AdMobConstant {
static let interstitial1ID = "..."
}
final class Interstitial: NSObject, GADFullScreenContentDelegate, ObservableObject {
private var interstitial: GADInterstitialAd?
override init() {
super.init()
requestInterstitialAds()
}
func requestInterstitialAds() {
let request = GADRequest()
request.scene = UIApplication.shared.connectedScenes.first as? UIWindowScene
ATTrackingManager.requestTrackingAuthorization(completionHandler: { status in
GADInterstitialAd.load(withAdUnitID: AdMobConstant.interstitial1ID, request: request, completionHandler: { [self] ad, error in
if let error = error {
print("Failed to load interstitial ad with error: \(error.localizedDescription)")
return
}
interstitial = ad
interstitial?.fullScreenContentDelegate = self
})
})
}
func showAd() {
let root = UIApplication.shared.windows.last?.rootViewController
if let fullScreenAds = interstitial {
fullScreenAds.present(fromRootViewController: root!)
} else {
print("not ready")
}
}
}
}
class AdsViewModel: ObservableObject {
static let shared = AdsViewModel()
#Published var interstitial = AdsManager.Interstitial()
#Published var showInterstitial = false {
didSet {
if showInterstitial {
interstitial.showAd()
showInterstitial = false
} else {
interstitial.requestInterstitialAds()
}
}
}
}
#main
struct YourApp: App {
let adsVM = AdsViewModel.shared
init() {
GADMobileAds.sharedInstance().start(completionHandler: nil)
}
var body: some Scene {
WindowGroup {
ContentView()
.environmentObject(adsVM)
}
}
Toggle the showInterstitial parameter in the AdsViewModel anywhere in the application and the advertisement will be shown.
In order to use the Admob docs with the newest SwiftUI release, you need to change this line...
.onAppear(perform: {
let request = GADRequest()
GADInterstitialAd.load(withAdUnitID:"ca-app-pub-3940256099942544/4411468910",
request: request,
completionHandler: { [self] ad, error in
if let error = error {
return
}
// Change these two lines of code
interstitial = ad
interstitial?.fullScreenContentDelegate = self
// To...
interstitial = ad
let root = UIApplication.shared.windows.first?.rootViewController
self.interstitial!.present(fromRootViewController: root!)
}
)
})
I have a video thats around 10 seconds long that I'd like to play on a loop as a fullscreen background image in one of my SwiftUI Views. How can I implement this?
First idea was working with Swift's import AVFoundation, but not sure if this is the right path.
You can use the AV family of frameworks and UIViewRepresentable to do this:
import SwiftUI
import AVKit
struct PlayerView: UIViewRepresentable {
func updateUIView(_ uiView: UIView, context: UIViewRepresentableContext<PlayerView>) {
}
func makeUIView(context: Context) -> UIView {
return PlayerUIView(frame: .zero)
}
}
In order for the video to loop I have added an observer and set the actionAtItemEnd to .none to support looping.
When the video reaches the end it will execute the playerItemDidReachEnd(...) method and seek to the beginning of the video and keep looping.
The example points to a remote video URL. If you want to point to a file within your application you can use Bundle.main.url to do so instead:
if let fileURL = Bundle.main.url(forResource: "IMG_2770", withExtension: "MOV") {
let player = AVPlayer(url: fileURL)
// ...
}
class PlayerUIView: UIView {
private let playerLayer = AVPlayerLayer()
override init(frame: CGRect) {
super.init(frame: frame)
let url = URL(string: "https://bitdash-a.akamaihd.net/content/sintel/hls/playlist.m3u8")!
let player = AVPlayer(url: url)
player.actionAtItemEnd = .none
player.play()
playerLayer.player = player
playerLayer.videoGravity = .resizeAspectFill
NotificationCenter.default.addObserver(self,
selector: #selector(playerItemDidReachEnd(notification:)),
name: .AVPlayerItemDidPlayToEndTime,
object: player.currentItem)
layer.addSublayer(playerLayer)
}
#objc func playerItemDidReachEnd(notification: Notification) {
if let playerItem = notification.object as? AVPlayerItem {
playerItem.seek(to: .zero, completionHandler: nil)
}
}
required init?(coder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
override func layoutSubviews() {
super.layoutSubviews()
playerLayer.frame = bounds
}
}
struct ContentView: View {
var body: some View {
NavigationView {
ZStack {
PlayerView()
.edgesIgnoringSafeArea(.all)
}
}
}
}
SwiftUI
As someone completely new to swift and for anyone who doesn't want to spend hours debugging this like I did. My use case was trying to create a login screen with a video playing in the background. I was struggling with the looping not working and then with the video stopping after a few seconds and starting again after the duration. This works for me.
Add a new view:
import SwiftUI
import AVKit
import AVFoundation
struct WelcomeVideo: View {
var body: some View {
WelcomeVideoController()
}
}
struct WelcomeVideo_Previews: PreviewProvider {
static var previews: some View {
WelcomeVideo()
}
}
final class WelcomeVideoController : UIViewControllerRepresentable {
var playerLooper: AVPlayerLooper?
func makeUIViewController(context: UIViewControllerRepresentableContext<WelcomeVideoController>) ->
AVPlayerViewController {
let controller = AVPlayerViewController()
controller.showsPlaybackControls = false
guard let path = Bundle.main.path(forResource: "welcome", ofType:"mp4") else {
debugPrint("welcome.mp4 not found")
return controller
}
let asset = AVAsset(url: URL(fileURLWithPath: path))
let playerItem = AVPlayerItem(asset: asset)
let queuePlayer = AVQueuePlayer()
// OR let queuePlayer = AVQueuePlayer(items: [playerItem]) to pass in items
playerLooper = AVPlayerLooper(player: queuePlayer, templateItem: playerItem)
queuePlayer.play()
controller.player = queuePlayer
return controller
}
func updateUIViewController(_ uiViewController: AVPlayerViewController, context: UIViewControllerRepresentableContext<WelcomeVideoController>) {
}
}
Then attach it to a view background:
.background(WelcomeVideo())
NOTE:
Make sure your video is imported to your project
Update the name of the video to what you need or refactor slightly to pass it in
Cheers!
This is what worked for me:
source
var body: some View {
ZStack{
HStack{
Spacer()
.frame(width: 50)
AmbienceVid()
}
.edgesIgnoringSafeArea(.all)
}
}
struct AmbienceVid: UIViewRepresentable {
func updateUIView(_ uiView: UIView, context: UIViewRepresentableContext<AmbienceVid>) {
}
func makeUIView(context: Context) -> UIView {
return PlayerUIView(frame: .zero)
}
}
class PlayerUIView: UIView {
private var playerLooper: AVPlayerLooper?
private var playerLayer = AVPlayerLayer()
required init?(coder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
override init(frame: CGRect) {
super.init(frame: frame)
// Load the resource
let fileUrl = Bundle.main.url(forResource: "ambiencevid", withExtension: "mp4")!
let asset = AVAsset(url: fileUrl)
let item = AVPlayerItem(asset: asset)
// Setup the player
let player = AVQueuePlayer()
playerLayer.player = player
playerLayer.videoGravity = .resizeAspectFill
layer.addSublayer(playerLayer)
// Create a new player looper with the queue player and template item
playerLooper = AVPlayerLooper(player: player, templateItem: item)
// Start the movie
player.play()
}
override func layoutSubviews() {
super.layoutSubviews()
playerLayer.frame = bounds
}
}
A looping, no-controls macOS implementation if people were searching for it.
import SwiftUI
import AVKit
struct NSVideoPlayer: NSViewRepresentable {
var videoURL: URL
func makeNSView(context: Context) -> AVPlayerView {
let item = AVPlayerItem(url: videoURL)
let queue = AVQueuePlayer(playerItem: item)
context.coordinator.looper = AVPlayerLooper(player: queue, templateItem: item)
let view = AVPlayerView()
view.player = queue
view.controlsStyle = .none
view.player?.playImmediately(atRate: 1)
return view
}
func updateNSView(_ nsView: AVPlayerView, context: Context) {}
func makeCoordinator() -> Coordinator {
Coordinator()
}
class Coordinator {
var looper: AVPlayerLooper? = nil
}
}
Tested in Swift 5 and SwiftUI 3
Viewmodel class functions
var avPlayer = AVPlayer()
func previewPlayer() -> AVPlayer {
self.avPlayer = AVPlayer(url: vedioData.preWithWithDecoURL!)
return self.avPlayer
}
func loopCurrentVedio() {
NotificationCenter.default.addObserver(forName: .AVPlayerItemDidPlayToEndTime, object: nil, queue: .main) { _ in
self.avPlayer.seek(to: .zero)
self.avPlayer.play()
}
}
In your SwiftUI View class
VideoPlayer(player: previewPlayer())
.frame(width: 300, height: 532, alignment: .center)
.cornerRadius(20)
.onAppear {
loopCurrentVedio()
}
This is the simplest solution I found
I created a tester app to test adding a GameCenter leaderboard to a simple SwiftUI game I am creating. I have been unable to figure out how to display the Game Center leaderboard with all the scores.
I have created a class containing all the Game Center functions (authentication and adding score to the leaderboard. This is called from the main ContentView view. I can't figure out how to make it show the leaderboard (or even the gamecenter login screen if the player isn't already logged in.)
This is my GameCenterManager class:
class GameCenterManager {
var gcEnabled = Bool() // Check if the user has Game Center enabled
var gcDefaultLeaderBoard = String() // Check the default leaderboardID
var score = 0
let LEADERBOARD_ID = "grp.colorMatcherLeaderBoard_1" //Leaderboard ID from Itunes Connect
// MARK: - AUTHENTICATE LOCAL PLAYER
func authenticateLocalPlayer() {
let localPlayer: GKLocalPlayer = GKLocalPlayer.local
localPlayer.authenticateHandler = {(ViewController, error) -> Void in
if((ViewController) != nil) {
print("User is not logged into game center")
} else if (localPlayer.isAuthenticated) {
// 2. Player is already authenticated & logged in, load game center
self.gcEnabled = true
// Get the default leaderboard ID
localPlayer.loadDefaultLeaderboardIdentifier(completionHandler: { (leaderboardIdentifer, error) in
if error != nil { print(error ?? "error1")
} else { self.gcDefaultLeaderBoard = leaderboardIdentifer! }
})
print("Adding GameCenter user was a success")
} else {
// 3. Game center is not enabled on the users device
self.gcEnabled = false
print("Local player could not be authenticated!")
print(error ?? "error2")
}
}
} //authenticateLocalPlayer()
func submitScoreToGC(_ score: Int){
let bestScoreInt = GKScore(leaderboardIdentifier: LEADERBOARD_ID)
bestScoreInt.value = Int64(score)
GKScore.report([bestScoreInt]) { (error) in
if error != nil {
print(error!.localizedDescription)
} else {
print("Best Score submitted to your Leaderboard!")
}
}
}//submitScoreToGc()
}
and here is the ContentView struct:
struct ContentView: View {
//GameCenter
init() {
self.gameCenter = GameCenterManager()
self.gameCenter.authenticateLocalPlayer()
}
#State var score = 0
var gcEnabled = Bool() //Checks if the user had enabled GameCenter
var gcDefaultLeaderboard = String() //Checks the default leaderboard ID
let gameCenter: GameCenterManager
/*End GameCenter Variables */
var body: some View {
HStack {
Text("Hello, world!")
Button(action: {
self.score += 1
print("Score increased by 10. It is now \(self.score)")
self.gameCenter.submitScoreToGC(self.score)
}) {
Text("Increase Score")
}
}
}
}
Would greatly appreciate any help in fixing the problem.
I have a fix.
I use Game Center successfully in my SwiftUI App Sound Matcher. Code snippets to follow.
The code doesn't exactly follow the SwiftUI declarative philosophy but it works perfectly. I added snippets to SceneDelegate and ContentView plus used I used a GameKitHelper class similar to the one Thomas created for his test app. I based my version on code I found on raywenderlich.com.
I actually tried using a struct conforming to UIViewControllerRepresentable as my first attempt, following the same line of thought as bg2b, however it kept complaining that the game centre view controller needed to be presented modally. Eventually I gave up and tried my current more successful approach.
For SwiftUI 1.0 and iOS 13
class SceneDelegate: UIResponder, UIWindowSceneDelegate {
let contentView = ContentView()
.environmentObject(GameKitHelper.sharedInstance) // publish enabled state
func scene(_ scene: UIScene, willConnectTo session: UISceneSession,
options connectionOptions: UIScene.ConnectionOptions) {
if let windowScene = scene as? UIWindowScene {
let window = UIWindow(windowScene: windowScene)
window.rootViewController = UIHostingController(rootView: contentView)
// new code to create listeners for the messages
// you will be sending later
PopupControllerMessage.PresentAuthentication
.addHandlerForNotification(
self,
handler: #selector(SceneDelegate
.showAuthenticationViewController))
PopupControllerMessage.GameCenter
.addHandlerForNotification(
self,
handler: #selector(SceneDelegate
.showGameCenterViewController))
// now we are back to the standard template
// generated when your project was created
self.window = window
window.makeKeyAndVisible()
}
}
// pop's up the leaderboard and achievement screen
#objc func showGameCenterViewController() {
if let gameCenterViewController =
GameKitHelper.sharedInstance.gameCenterViewController {
self.window?.rootViewController?.present(
gameCenterViewController,
animated: true,
completion: nil)
}
}
// pop's up the authentication screen
#objc func showAuthenticationViewController() {
if let authenticationViewController =
GameKitHelper.sharedInstance.authenticationViewController {
self.window?.rootViewController?.present(

}
}
EDIT 2023: as mentioned in comments, GKScore is now deprecated. I don't have an updated solution to present.
Partial answer for you here. I'm able to download leaderboard scores and display them in a SwiftUI list provided the device (or simulator) is logged into iCloud and has GameCenter already enabled in settings. I have not attempted to make a gameCenter authentication view controller appear if that is not the case.
Thank you for the code in your question. I used your GameCenterManager() but put it in my AppDelegate:
let gameCenter = GameCenterManager()
Below is my ShowRankings.swift SwiftUI View. I'm able to successfully authenticate and get the scores. But I still have "anomalies". The first time I run this (in simulator) I get the expected "User is not logged into Game Center" error indicating the ViewController in your GameCenterManager is not nil (I never even attempt to display it). But then I'm able to successfully get the scores and display them in a list.
import SwiftUI
import GameKit
struct ShowRankings: View {
let appDelegate = UIApplication.shared.delegate as! AppDelegate
let leaderBoard = GKLeaderboard()
#State var scores: [GKScore] = []
var body: some View {
VStack {
Button(action: {
self.updateLeader()
}) {
Text("Refresh leaderboard")
}
List(scores, id: \.self) { score in
Text("\(score.player.alias) \(score.value)")
}
}.onAppear() {
self.appDelegate.gameCenter.authenticateLocalPlayer()
self.updateLeader()
}
}
func updateLeader() {
let leaderBoard: GKLeaderboard = GKLeaderboard()
leaderBoard.identifier = "YOUR_LEADERBOARD_ID_HERE"
leaderBoard.timeScope = .allTime
leaderBoard.loadScores { (scores, error) in
if let error = error {
debugPrint("leaderboard loadScores error \(error)")
} else {
guard let scores = scores else { return }
self.scores = scores
}
}
}
}
An alternative solution is to create a UIViewControllerRepresentable for GameCenter which takes a leaderboard ID to open. This makes it simple to open a specific leader board.
public struct GameCenterView: UIViewControllerRepresentable {
let viewController: GKGameCenterViewController
public init(leaderboardID : String?) {
if leaderboardID != nil {
self.viewController = GKGameCenterViewController(leaderboardID: leaderboardID!, playerScope: GKLeaderboard.PlayerScope.global, timeScope: GKLeaderboard.TimeScope.allTime)
}
else{
self.viewController = GKGameCenterViewController(state: GKGameCenterViewControllerState.leaderboards)
}
}
public func makeUIViewController(context: Context) -> GKGameCenterViewController {
let gkVC = viewController
gkVC.gameCenterDelegate = context.coordinator
return gkVC
}
public func updateUIViewController(_ uiViewController: GKGameCenterViewController, context: Context) {
return
}
public func makeCoordinator() -> GKCoordinator {
return GKCoordinator(self)
}
}
public class GKCoordinator: NSObject, GKGameCenterControllerDelegate {
var view: GameCenterView
init(_ gkView: GameCenterView) {
self.view = gkView
}
public func gameCenterViewControllerDidFinish(_ gameCenterViewController: GKGameCenterViewController) {
gameCenterViewController.dismiss(animated: true, completion: nil)
}
}
To use just add the below wherever it is needed to display a leaderboard.
GameCenterView(leaderboardID: "leaderBoardID")
I'm adopting SwiftUI for one of my previous apps, and at some point I need to add an event to the iOS calendar.
Doing some researches on both the Apple Developer Forums and Stack Overflow, I came up with the following solution, that makes use of the UIViewControllerRepresentable protocol in order to still be able to use UIViewControllers with SwiftUI (you can find below the links to the discussions, for your reference).
Discussion on the Apple Dev Forums:
https://forums.developer.apple.com/thread/120372
Discussion on Stack Overflow:
SwiftUI: Send email
I'm almost there, but what I'm missing now it's the control of the authorization status to access the device calendar, and to trigger the request for such authorization in case it's required.
In Swift this would be the function to invoke to trigger the request, but I'm not sure how to handle this in my EKEventWrapper.
func requestAccess(to entityType: EKEntityType,
completion: #escaping EKEventStoreRequestAccessCompletionHandler)
Any ideas?
Thanks a lot!
My solution up to this point:
import Foundation
import SwiftUI
import EventKitUI
let eventStore = EKEventStore()
struct EKEventWrapper: UIViewControllerRepresentable {
typealias UIViewControllerType = EKEventEditViewController
#Binding var isShowing: Bool
var theEvent = EKEvent.init(eventStore: eventStore)
func makeUIViewController(context: UIViewControllerRepresentableContext<EKEventWrapper>) -> EKEventEditViewController {
let calendar = EKCalendar.init(for: .event, eventStore: eventStore)
theEvent.startDate = Date()
theEvent.endDate = Date()
theEvent.title = "Meeting"
theEvent.calendar = calendar
let controller = EKEventEditViewController()
controller.event = theEvent
controller.eventStore = eventStore
controller.editViewDelegate = context.coordinator
return controller
}
func updateUIViewController(_ uiViewController: EKEventWrapper.UIViewControllerType, context: UIViewControllerRepresentableContext<EKEventWrapper>) {
//
}
func makeCoordinator() -> Coordinator {
return Coordinator(isShowing: $isShowing)
}
class Coordinator : NSObject, UINavigationControllerDelegate, EKEventEditViewDelegate {
#Binding var isShowing: Bool
init(isShowing: Binding<Bool>) {
_isShowing = isShowing
}
func eventEditViewController(_ controller: EKEventEditViewController, didCompleteWith action: EKEventEditViewAction) {
switch action {
case .canceled:
print("Canceled")
isShowing = false
case .saved:
print("Saved")
do {
try controller.eventStore.save(controller.event!, span: .thisEvent, commit: true)
}
catch {
print("Problem saving event")
}
isShowing = false
case .deleted:
print("Deleted")
isShowing = false
#unknown default:
print("I shouldn't be here")
isShowing = false
}
}
}
}
I believe the below will do this, I have tested it in SwiftUI using a button to action the function. First post ever so apologies If I am totally off the mark!
import SwiftUI
import EventKit
import EventKitUI
struct calaccess: View {
var eventstore = EKEventStore()
var body: some View {
func accesscalender(CalAccess: EKEventStore) {
let eventstore = EKEventStore()
eventstore.requestAccess(to: EKEntityType.event,completion:
{(granted, error) in
if !granted {
print("Access to store not granted")
}
}),,,,
