I embedded a vertical scrollview to a calendar that was originally horizontally navigation with buttons. But its isn't scrolling changing months. What am I missing? let days = ["SUN", "MON", "TUE", "WED", "THU", "FRI", "SAT"] @State private var selectedMonth = 0 @State private var selectedDate = Date() @State private var path = NavigationPath() var body: some View { NavigationStack(path: $path) { ScrollView { VStack { Rectangle() .frame(height: 1) .foregroundColor(.gray) VStack(spacing: 20) { // Month Selection HStack { Spacer() Button { withAnimation { selectedMonth -= 1 } } label: { Image(systemName: "lessthan.circle.fill") .resizable() .scaledToFit() .frame(width: 32, height: 32) .foregroundColor(.gray) } Spacer() Text(selectedDate.monthYearFormat()) .font(.title2) Spacer() Button { withAnimation { selectedMonth += 1 } } label: { Image(systemName: "greaterthan.circle.fill") .resizable() .scaledToFit() .frame(width: 32, height: 32) .foregroundColor(.gray) } Spacer() } HStack { ForEach(days, id:\.self) { day in Text(day) .font(.system(size: 12, weight: .medium)) .frame(maxWidth: .infinity) } } LazyVGrid(columns: Array(repeating: GridItem(.flexible()), count: 7), spacing: 20) { ForEach(fetchDates()) { value in ZStack { if value.day != -1 { let hasAppts = manager.days.contains(value.date.monthDayYearFormat()) NavigationLink(value: AppRouter.day(date: value.date)) { Text("\(value.day)") .foregroundColor(hasAppts ? .blue : .black) .fontWeight(hasAppts ? .bold : .none) .background { ZStack(alignment: .bottom) { Circle() .frame(width: 48, height: 48) .foregroundColor(hasAppts ? .blue.opacity(0.1) : .clear) if value.date.monthDayYearFormat() == Date().monthDayYearFormat() { Circle() .frame(width: 8, height: 8) .foregroundColor(hasAppts ? .blue : .gray) } } } } .disabled(!hasAppts) } else { Text("") } } .frame(width: 32, height: 32) } } } .padding() } } .navigationDestination(for: AppRouter.self) { router in switch router { case .day(let date): DayView(path: $path, currentDate: date) .environmentObject(manager) case .booking(let date): BookingView(path: $path, currentDate: date) .environmentObject(manager) case .confirmation(let date): ConfirmationView(path: $path, currentDate: date) } } .frame(maxHeight: .infinity, alignment: .top) .onChange(of: selectedMonth) { _ in selectedDate = fetchSelectedMonth() } } } func fetchDates() -> [CalendarDate] { let calendar = Calendar.current let currentMonth = fetchSelectedMonth() var dates = currentMonth.datesOfMonth().map({ CalendarDate(day: calendar.component(.day, from: $0), date: $0) }) let firstDayOfWeek = calendar.component(.weekday, from: dates.first?.date ?? Date()) for _ in 0..<firstDayOfWeek - 1 { dates.insert(CalendarDate(day: -1, date: Date()), at: 0) } return dates } func fetchSelectedMonth() -> Date { let calendar = Calendar.current let month = calendar.date(byAdding: .month, value: selectedMonth, to: Date()) return month! } }

Not sure what Im doing wrong here. Says "Cannot convert value of type 'String' to expected argument type 'Int'". let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "calCell", for: indexPath) as! CalendarCell cell.dayOfMonth.text = totalSquares[indexPath.item] //show the weekend days in different color switch indexPath.item { case 0,6,7,13,14,20,21,27,28,34,35,41: if Int(cell.dayOfMonth.text = "\(indexPath.item)" > 0 { cell.dayOfMonth.textColor = UIColor.lightGray } default: break } return cell }

Im trying to extract the IP address that is nested in html and print it out to a string.&lt;ul&gt; &lt;li&gt;IP Address: &lt;span class="darktext"&gt;199.123.456.789&lt;/span&gt; &lt;/li&gt; &lt;li&gt;Internet Service Provider: &lt;span class="darktext"&gt;Optimum WiFi&lt;/span&gt; &lt;/li&gt; &lt;li&gt;City: &lt;span class="darktext"&gt;My City&lt;/span&gt; &lt;/li&gt; &lt;li&gt;State/Region: &lt;span class="darktext"&gt;New City&lt;/span&gt; &lt;/li&gt; &lt;li&gt;Country: &lt;span class="darktext"&gt;United States&lt;/span&gt; &lt;/li&gt; &lt;li&gt;Browser: &lt;span class="darktext"&gt;TextFromURL&lt;/span&gt; &lt;/li&gt; &lt;li&gt;Operating System: &lt;span class="darktext"&gt;&lt;/span&gt; &lt;/li&gt; &lt;li&gt;Screen Resolution: &lt;span id="resolution" class="darktext"&gt;&lt;/span&gt; &lt;/li&gt; &lt;/ul&gt;

How can I customize an UIDatePicker to show: mm:dd:yyyy and the time with only two options to choose from: hh1 or hh2: (07) hrs or (22)hrs?example: (scrollable) Date: May 23 2020 Time: 0700 (option 1) 2200 (option 2)

let longPressGesture = UILongPressGestureRecognizer(target: self, action: #selector(handleLongPress(gesture:))) calendarView.addGestureRecognizer(longPressGesture) } @objc func handleLongPress(gesture: UILongPressGestureRecognizer) { guard gesture.state == .began else {return} let position = gesture.location(in: collectionView) if let indexPath = collectionView.indexPathForItem(at: position) { guard let modalCalVC = self.storyboard?.instantiateViewController(identifier: "ModalCalViewController") as? ModalCalViewController else { print("ModalCalViewController cannot be instantiated") return } let value = true //Get the value you want to pass from `indexPath` modalCalVC.passedValue = value present(modalCalVC, animated: true, completion: nil) } else { print("Long press not on a cell") } }I dont understand why it crashes I get Fatal error: Unexpectedly found nil while implicitly unwrapping an Optional value: file.swift, Line 10

I have a collection view (Calendar) and I have my modal view and I want the modal view to display what is in the cell when its selected.Im not sure how do I go about doing this?So far I changed the color of the cells background when selected.How do I call and animate the child view controller?and then display that cells content?// Reuseable Cell setupViews() myCollectionView.delegate=self myCollectionView.dataSource=self myCollectionView.register(dateCVCell.self, forCellWithReuseIdentifier: "Cell") }// cell selected BG color change func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) { let cell=collectionView.cellForItem(at: indexPath) cell?.backgroundColor=Colors.blue let lbl = cell?.subviews[1] as! UILabel lbl.textColor=UIColor.white }

Im trying to make a generated array of (6) numbers display per cell, of a collection view with reusable cells.The array is being generated with this:let original = [1, 2, 3, 4, 5, 6] var currentArray = original print("currentArray =", currentArray) var stop = false repeat { currentArray = currentArray.map() { ($0 + 2) % 25 + 1} print("currentArray =", currentArray) stop = currentArray[0] == 25 } while !stopmy Collection View is being setup here...&lt;ViewController.swift&gt;func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -&gt; UICollectionViewCell { let cell=collectionView.dequeueReusableCell(withReuseIdentifier: "Cell", for: indexPath) as! discoCueCell cell.backgroundColor=UIColor.clearAny ideas???
