This is my full error
Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'request for rect at invalid index path (<NSIndexPath: 0xc000000000000016> {length = 2, path = 0 - 0})
I have this code for my numberOfRows
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if monthlyExpenses.count == 0{
noExpenseLabel.isHidden = false
}
return monthlyExpenses.count
}
and here is the code for my cellForRowAtIndexPath
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "monthlyCell", for: indexPath) as! MonthlyExpenseTableViewCell
//var newMode2:Bool? = nil
tableView.rowHeight = UITableViewAutomaticDimension
tableView.estimatedRowHeight = 64
let expense = monthlyExpenses[indexPath.row]
let date = expense.modificationDate
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "EEEE d MMMM"
let dateString = dateFormatter.string(from: date! as Date).uppercased()
for expense in monthlyExpenses {
if expense.modificationDate?.convertToMonth() != monthDisplayed.text{
if let expenseSorter = monthlyExpenses.index(of: expense) {
monthlyExpenses.remove(at: expenseSorter)
}
}
}
CoreDataHelper.save()
if indexPath.row == 0{
newMode = true
}
if indexPath.row>=1{
monthlyExpenses.sorted(by: { $0.modificationDate as! Date > $1.modificationDate as! Date})
let previousExpensesData = monthlyExpenses[indexPath.row - 1].modificationDate
let day = Calendar.current.component(.day, from: monthlyExpenses[indexPath.row].modificationDate as! Date) // Do not add above 'date' value here, you might get some garbage value. I know the code is redundant. You can adjust that.
let previousDay = Calendar.current.component(.day, from: monthlyExpenses[indexPath.row - 1].modificationDate! as Date)
if day == previousDay {
newMode = false
} else {
newMode = true

I tried executing the code after CoreDataHelper.save() with a condition
if monthlyExpense.count>=1
but that didn't seem to do anything. Ideally for a month with no expense in it, it should print nothing and a default view which is called NoExpenseLabel, should be visible. Why am I getting this error.
This is a Year View Controller I have, whenever I click on a cell, it performs the code above. So if July is clicked, only expenses in July are displayed. This is why I have the monthly expenses(remove:) code.
Please don't remove monthlyExpenses in cellForRowAt indexPath. Because when the tableView call again cellForRowAt indexPath the array will have less elements that you said in numberOfRowsInSection. You need to remove your array's elements before and then call reloadData.
