I've added long press programmatically but it does nothing. What am I doing wrong? Thanks in advance. import UIKit class ViewController: UIViewController, UICollectionViewDelegate, UICollectionViewDataSource, UIGestureRecognizerDelegate { @IBOutlet weak var monthLabel: UILabel! @IBOutlet weak var collectionView: UICollectionView! var selectedDate = Date() var totalSquares = [String]() override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view. setCellView() setMonthView() func setupLongGestureRecognizerOnCollection() { let longPressedGesture = UILongPressGestureRecognizer(target: self, action: #selector(handleLongPress(gestureRecognizer:))) longPressedGesture.minimumPressDuration = 0.5 longPressedGesture.delegate = self longPressedGesture.delaysTouchesBegan = true collectionView?.addGestureRecognizer(longPressedGesture) } } func setCellView() { let width = (collectionView.frame.size.width - 2) / 8 let height = (collectionView.frame.size.height - 2) / 8 let flowLayout = collectionView.collectionViewLayout as! UICollectionViewFlowLayout flowLayout.itemSize = CGSize(width: width, height: height) } func setMonthView(){ totalSquares.removeAll() let daysInMonth = CalendarHelper().daysInMonth(date: selectedDate) let firstDayOfMonth = CalendarHelper().firstOfMonth(date: selectedDate) let startingSpaces = CalendarHelper().weekDay(date: firstDayOfMonth) var count: Int = 1 while(count <= 42) { if(count <= startingSpaces || count - startingSpaces > daysInMonth) { totalSquares.append("") } else { totalSquares.append(String(count - startingSpaces)) } count += 1 } monthLabel.text = CalendarHelper().monthString(date: selectedDate) + " " + CalendarHelper().yearString(date: selectedDate) collectionView.reloadData() } func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int { return totalSquares.count } func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell { let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "calCell", for: indexPath) as!

I have a collectionview of UILabels. when you tap a cell it should display its detail onto a pop up modal view. How do you display it onto that modal view in the same View controller? 2a. How can you cycle (loop) a group of arrays via UILabel forward and backwards in cells? 2b. How do you filter the arrays so that it always shows with a specific cell? (eg: Cell 2 will always have "D, E, F" when scrolling through) func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int { return totalSquares.count } func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell { let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "calCell", for: indexPath) as! CalendarCell cell.dayOfMonth.text = totalSquares[indexPath.item] return cell } // Cell 1 Cell 2 Cell 3 let myArray: String = [[" A, B, C"], ["D, E, F"], ["G, H, I"]] etc..

I have a ViewController that calls a Xib view to popup (as a PressentationController). I need to put a single cell collectonview on that Xib view. How can I go about doing that because I cannot embed a collectionview in a Xib via storyboard. Is there a way to do that programmatically?

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 }

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! } }

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() }

can't see what the problem is .. Im getting the error: Type '()' cannot conform to 'View' struct CalendarView: View { @StateObject private var viewModel = CalendarViewModel() @State private var selectedDate: CalendarDate? @State private var showModal = false var body: some View { VStack { Text("Calendar App") .font(.largeTitle) .padding() GridStack(rows: 5, columns: 7) { row, col in let index = row * 7 + col if index < viewModel.calendarDates.count { let calendarDate = viewModel.calendarDates[index] Text("\(Calendar.current.component(.day, from: calendarDate.date))") .frame(width: 40, height: 40) .background(calendarDate.isSelected ?
