I'm trying to display one embedded content by using the WKWebView and I can not click some of these links. Is there anything I did wrong?Here is the Link which I get the embedded content from:https://publish.twitter.com Here is the embedded content:<a class="twitter-timeline" href="https://twitter.com/Google?ref_src=twsrc%5Etfw">Tweets by Google</a><script async src="https://platform.twitter.com/widgets.js" charset="utf-8"></script>Here is my code:import UIKit

Hello, I'm new to SwiftUI and right now I'm trying to create one simple Application by using @State, @ObservedObject, and @Environment. For some reason, I got error "Cannot preview in this file" after I tried to add Environment object. The canvas is not working, but I can actually run the application in a simulator and actual device without any problem. Here is how I added my environment object. SceneDelegate: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).
let channelData = ChannelData()
// Create the SwiftUI view that provides the window contents.
let contentView = ContentView().environmentObject(channelData)
// 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(
}
}ChannelData class:import Combine

Text(videoIdea.title)

Text("Add Channel")

Button(action: {
self.showingSecondVC.toggle()

SecondView(videoTitle: self.$videoIdea.title, videoContent: self.$videoIdea.contentIdea).environmentObject(self.channelData)

Hello guys, like the title says. I'm tying to implment code so I can report the the call before I receive the remote VoIP notification call in methodfunc pushRegistry(_ registry: PKPushRegistry, didReceiveIncomingPushWith payload: PKPushPayload, for type: PKPushType, completion pushProcessingCompletion: @escaping () -> Void)But under my research time I did get banned from the system and I was not aware for the change which apple announced before:https://developer.apple.com/documentation/pushkit/pkpushregistrydelegate/2875784-pushregistry?language=objcOn iOS 13.0 and later, if you fail to report a call to CallKit, the system will terminate your app. Repeatedly failing to report calls may cause the system to stop delivering any more VoIP push notifications to your app.So my question is is there any chance I can get myself "unban" from the system so I can at least debug my code to verify if my code is working or not

Hellow, I was using one iPhone with version 12.4 to run application for development. Suddely when I updated from version 12.4 to 13.1, one of my http rest api just stopped working and it returns me error:"019-09-25 16:56:56.578750+0200 SmaforetagarnasAPP[487:44045] task challenge NSURLAuthenticationMethodServerTrustFAILURE: Error Domain=NSURLErrorDomain Code=-999 "cancelled" UserInfo={NSErrorFailingURLStringKey=https://appapi2.bankid.com/rp/v5/auth, NSErrorFailingURLKey=https://appapi2.bankid.com/rp/v5/auth, _NSURLErrorRelatedURLSessionTaskErrorKey=( "LocalDataTask <1FDB0948-469A-4333-BA23-9CAB3452F59B>.<1>"), _NSURLErrorFailingURLSessionTaskErrorKey=LocalDataTask <1FDB0948-469A-4333-BA23-9CAB3452F59B>.<1>, NSLocalizedDescription=cancelled}2019-09-25 16:56:56.590973+0200 SmaforetagarnasAPP[487:44045] Task <1FDB0948-469A-4333-BA23-9CAB3452F59B>.<1> HTTP load failed, 0/0 bytes (error code: -999 [1:89])2019-09-25 16:56:56.592230+0200 SmaforetagarnasAPP[487:44045] Connection 3: unable to determine interface type without an established connection2019-09-25 16:56:56.592313+0200 SmaforetagarnasAPP[487:44045] Connection 3: unable to determine fallback status without a connection"Im using Alamofire SessionManager to make the http callThe http call requires certificate and here is my code:Calling function:func authenticate(completion: @escaping ModelCompletion<Bool>) {

I want to know if it's possible to disable full-screen mode when WKWebView open local video file by using the file's local url.Because I always receive error "Plug-in handled load" when WKWebView is loading(but the video is still playing in full screen mode).I checked some solutions from StackOverFlow:https://stackoverflow.com/a/10194888/11055217https://stackoverflow.com/questions/2143763/does-uiwebview-send-the-same-user-agent-in-the-request-headers-as-mobile-safari/5916330#5916330But these link still cannot solve my problem.Here is my WKWebView code setup://

Hello, Im trying to make a API call to a server by using a https certificate, but I already get stuck at the server trust stage. I'm using a server certificate with extension .cer and here is my code:private func shouldTrust(protectionSpace: URLProtectionSpace) -> Bool {
guard let trust = protectionSpace.serverTrust else { return false }
// First try evaluating trust with any custom anchor. If that succeeds, we're good to go.
var trustResult = SecTrustResultType.invalid
var err = SecTrustEvaluate(trust, &trustResult)
guard err == errSecSuccess else { return false }
if [.proceed, .unspecified].contains(trustResult) { return true }
// If it fails, apply our custom anchor and try again.
let root = Bundle.main.certificateForBankIDPayment(named: "sebtekniskbankinfoserverca")
err = SecTrustSetAnchorCertificates(trust, [root] as NSArray)
guard err == errSecSuccess else { return false }
err = SecTrustEvaluate(trust, &trustResult)
guard err == errSecSuccess else { return false }
return [.proceed, .unspecified].contains(trustResult)

Right now I'm looking for a good tool which can help me track down user activity when they are using application. I know there is App Analytics, but I need some more information which is a little more specific. Information which I would like to know is:How many user clicked on one specific button, image, text or link.How many times user has viewd on one specific UI page.
I was trying to create a UIButton by code, and I want to add the UIButton as a subview into a UITextView. Here is the code:private func initTermsTextView() { let filePath = Bundle.main.path(forResource: "terms", ofType: "html", inDirectory: nil, forLocalization: nil) ?? "" let htmlString = try! String(contentsOfFile: filePath) let htmlData = NSString(string: htmlString).data(using: String.Encoding.unicode.rawValue) let options = [NSAttributedString.DocumentReadingOptionKey.documentType: NSAttributedString.DocumentType.html] let attributedString = try! NSMutableAttributedString(data: htmlData!, options: options, documentAttributes: nil) let font = UIFont(name: "BrandonGrotesque-Regular", size: 20) ?? UIFont.systemFont(ofSize: 20) attributedString.setFontFace(font: font, color: UIColor.grayMetalic()) let btn: UIButton = UIButton(frame: CGRect(x: 8, y: termsTextView.contentSize.height*11-135, width: 48, height: 48)) btn.setTitle("asdasdasdasda", for: .normal) btn.addTarget(self, action: #selector(buttonAction), for: .touchUpInside) btn.clipsToBounds = true btn.setImage(UIImage(named: "uncheckedBox"), for: .normal) let path = UIBezierPath(rect: CGRect(x: 8, y: termsTextView.contentSize.height*11-135, width: btn.frame.width, height: btn.frame.height)) self.termsTextView.textContainer.exclusionPaths = [path] self.termsTextView.attributedText = attributedString self.termsTextView.text.append(TermConditionSingleton.getInstance.setTCGetString()) self.termsTextView.addSubview(btn) }Since I have no idea how to add UIButton at the bottom of a UITextView, I did hardcore and count out the UITextView length(text length*11-135) and added the button under the UITextView.After I was running my code with devices which is above the iPhone 6 (include 6s and plus) and the UIButton has displayed in the UITextView. But when I tried with iPhone 6 plus and iPhone 6s plus, the UIButton sub view did not show in the UITextView and I have no idea why.Is there any way I can fix this type of problem?
