Custom Calendar View Not Displaying Correct Dates on iPhone 14 with iOS 17
Hey everyone, I'm running into an issue that's driving me crazy... I'm reviewing some code and I am trying to implement a custom calendar view using SwiftUI, but I'm working with an scenario where the displayed dates do not align correctly with the actual calendar days on my iPhone 14 running iOS 17. I have created a simple grid layout that should represent the days of a month, but the first day of the month is not starting on the correct weekday, and some days are missing from the display altogether. Here's a snippet of my code: ```swift struct CalendarView: View { let month: Int let year: Int var body: some View { let days = self.getDaysInMonth(month: month, year: year) let firstDayOfMonth = self.getFirstDayOfMonth(month: month, year: year) let totalDays = days.count let gridItems = Array(repeating: GridItem(.flexible()), count: 7) LazyVGrid(columns: gridItems) { ForEach(0..<totalDays + firstDayOfMonth, id: \._self) { index in if index < firstDayOfMonth { Text("") // Empty cells for days before the first of the month } else { Text(\(days[index - firstDayOfMonth])) } } } } func getDaysInMonth(month: Int, year: Int) -> [Int] { let dateComponents = DateComponents(year: year, month: month) let date = Calendar.current.date(from: dateComponents)! let range = Calendar.current.range(of: .day, in: .month, for: date)! return Array(range) } func getFirstDayOfMonth(month: Int, year: Int) -> Int { let dateComponents = DateComponents(year: year, month: month, day: 1) let date = Calendar.current.date(from: dateComponents)! return Calendar.current.component(.weekday, from: date) - 1 // Adjusting for zero-based index } } ``` I have verified that the `getDaysInMonth` function returns the correct number of days, but when I call `getFirstDayOfMonth`, it seems to give an offset that causes the grid to misalign. I have checked the calculations and even added print statements to debug, but when I run the app, I get an index out of range behavior when trying to access the days array. I've tried adjusting the indices and double-checking the `getDaysInMonth` function to ensure it returns the correct days, but I still see inconsistencies in the calendar display. What could I be missing here? I'm developing on Windows 11 with Swift. Thanks for your help in advance! This is my first time working with Swift 3.9. Any ideas what could be causing this?
