Hi! I'm trying to display a pdf inside my iOS app and I'm using the code displayed below, but for every self inside it I'm getting this error: Cannot find 'self' in scope // //  gimnaziumStundenplan.swift //  stundenplan // //  Created by Alex on 04/09/2021. // import UIKit import PDFKit private func createPdfView(withFrame frame: CGRect) -> PDFView {     let pdfView = PDFView(frame: frame)     pdfView.autoresizingMask = [.flexibleWidth, .flexibleHeight]     pdfView.autoScales = true     return pdfView } private func createPdfDocument(forFileName fileName: String) -> PDFDocument? {     if let resourceUrl = self.resourceUrl(forFileName: fileName) {         return PDFDocument(url: resourceUrl)     }          if let resourceUrl = URL(string: "https://web.stanford.edu/class/archive/cs/cs161/cs161.1168/lecture4.pdf") {             return PDFDocument(url: resourceUrl)         }         return nil } private func displayPdf() {     let pdfView = self.createPdfView(withFrame: self.view.bounds)     if let pdfDocument = self.createPdfDocument(forFileName: "heaps") {         self.view.addSubview(pdfView)         pdfView.document = pdfDocument     } } }

Hi! I'm creating an app for iOS and I want just to display a pdf from an external url with the width of 300 and height of 500. I tried with UiWebView but it is no longer supported. import SwiftUI let webView = UIWebView(frame: CGRect(x: 10, y: 10, width: 500, height: 300)) let targetURL = NSURL(string: "https://www.example.com/document.pdf")! let request = NSURLRequest(URL: targetURL) webView.loadRequest(request) struct StundenplanCard: View {     var body: some View {         VStack(spacing: 20) {             Text("Gimnazium") // here should be displayed the pdf         }     } } struct StundenplanCard_Previews: PreviewProvider {     static var previews: some View {         StundenplanCard().previewLayout(.fixed(width: 320, height: 640))     } }

Hello, I am making an app for an organization, but I'm not 100% sure if it will meet all the requirements (my app is a few updating websites with news for the organization and I don't think that it will be accepted on the app store). Is there a way to get a link for my app (just to share in my organization), so my app doesn't need to be publicly available on the app store?

Hi, I'm trying to test an app on a iPhone and I get this error Unable to install "[app name]".

Hello, I'm trying to show a pdf inside my app, using webkit, with the code below. When I open the app, everything is fine, but after I'm switching to another tab (another page), the content of the pdf doesn't show up (just the pages don't show up, but page counter is still there). view(request: URLRequest(url: URL(string: "[the url to the pdf file]")!)).previewLayout(.fixed(width: .infinity, height: .infinity)) .tabItem {     Image("Lyzeum")     Text("Lyzeum") } Also the URLRequest function: struct view : UIViewRepresentable {     let request: URLRequest     func makeUIView(context: Context) -> WKWebView  {         return WKWebView()     }     func updateUIView(_ uiView: WKWebView, context: Context) {         uiView.load(request)     } }

Hi, I'm trying to add haptic feedback to a tabItem inside a tabView with this code (just a part of the ContentView file): @State private var tabSelection = 1     var body: some View {             TabView(selection: $tabSelection) {                 view(request: URLRequest(url: URL(string: "https://gnets.myds.me/stundenplan/gymnasium.php")!)).previewLayout(.fixed(width: .infinity, height: .infinity))                     .tabItem {                         Image("1")                         Text("Gymnasium")                     }.onTapGesture {                         self.tabSelection = 1                     }                 view(request: URLRequest(url: URL(string: "https://gnets.myds.me/stundenplan/lyzeum.php")!)).previewLayout(.fixed(width: .infinity, height: .infinity))                     .tabItem {                         Image("2")                         Text("Lyzeum")                     }.onTapGesture {                         self.tabSelection = 2                     }                 view(request: URLRequest(url: URL(string: "https://gnets.myds.me/stundenplan/nou/")!)).previewLayout(.fixed(width: .infinity, height: .infinity))                     .tabItem {                         Image("3")                         Text("Neuigkeiten")                     }.onTapGesture {                         self.tabSelection = 3                     }             }.onTapGesture {                 let impactLight = UIImpactFeedbackGenerator(style: .light)                 impactLight.impactOccurred()             }     } After testing on a iPhone, the haptic feedback acts in on click of a tabItem, and also on click of the entire view (which is fine), but the view (tab) doesn't change. (I added the variable tabSelection to make the tabItem force change the view, but it still doesn't work.) What I need is that on click of a tabItem, the view changes (as normal), but also gets a light haptic feedback.

Hi! I'm just starting out with making iOS app and I want to publish my first app, but before I pay 99$ for the Apple Developer Program, I want to know if the App Store Review accepts WebKit Websites with the following code: import SwiftUI import WebKit struct view : UIViewRepresentable {     let request: URLRequest     func makeUIView(context: Context) -> WKWebView  {         return WKWebView()     }     func updateUIView(_ uiView: WKWebView, context: Context) {         uiView.load(request)     } } struct ContentView: View {     var body: some View {             TabView {                 view(request: URLRequest(url: URL(string: "https://gnets.myds.me/cloud/gymnazium.pdf")!)).previewLayout(.fixed(width: .infinity, height: .infinity))                     .tabItem {                         Image("1")                         Text("Gymnasium")                     }                 view(request: URLRequest(url: URL(string: "https://gnets.myds.me/cloud/lyzeum.pdf")!)).previewLayout(.fixed(width: .infinity, height: .infinity))                     .tabItem {                         Image("2")                         Text("Lyzeum")                     }                 view(request: URLRequest(url: URL(string: "https://gnets.myds.me/stundenplan/nou/")!)).previewLayout(.fixed(width: .infinity, height: .infinity))                     .tabItem {                         Image("3")                         Text("Neuigkeiten")                     }             }     } } struct ContentView_Previews : PreviewProvider {     static var previews: some View {         ContentView()     } }

Hi, I'm building an app for a organisation that requires to send a notification every time the content of a website changes (the website updates). (There is a list of news that are displayed into a webkit view.) I could do it with APNs, but I think it is too complicated for just a simple task like this. I tried with user notification, but I don't know how to store a small copy of the website and every day check if the copy and the website are the same. If they are not the same, a notification should be pushed. Could anyone help? Thank you, Alex Sofonea

I am trying to generate the signature for a JWT using a .p8 private key from Apple for APNs in PHP. If I try to use the following command hash_hmac('sha256', $header . '.' . $payload, $key), when checking it in Apple's JSON Web Token Validator, I get that the signature is invalid. I have also tried converting the .p8 private key to a PEM file and importing it into the OpenSSL library, but I am still getting the error message openssl_sign(): Supplied key param cannot be coerced into a private key. But I generate the JWT using Apple's JSON Web Token Generator, everything goes well, even the request to APNs. Thank you in advance!
