How to iterate Arrays inside another array inside tableview cell for row

Question

Output of array looks like [[3, 1], [2, 1], [3, 1], [4, 1], [6, 1]] I want particular values 3 and 1 for indexpath.row 1 and so on.

var weekdays = [Int]()
weekdays.append(daysArr)  

 Attempt 1
 for i in weekdays  {
      for j in i
      } 
}

On this line - for j in i I get error like "Type any" does not confirm to protocol 'Sequence'

I tried changing type from any to other but nothing seems to be working

If the array is nested declare it as

var weekdays = [[Int]]()

In cellForRow get the inner array with indexPath.row and iterate it the usual way

let weekdayArray = weekdays[indexPath.row]
for aWeekday in weekdayArray {
    print(aWeekday)
}

Can you please confirm why question is downvote ?| Also there is one issue with your answer i.e aWeekday[3, 1] But how to get value 3 and 1 .. I mean how can I iterate over aWeekday

I didn't downvote. But I can imagine that people are downvoting because the question is a bit ambiguous, for example it's missing in which line the error occurs and is weekdays the data source array of something else? And in my example weekdayArray will contain [3, 1]. The loop is iterating over weekdayArray

It's much better. By the way: The error (message) occurs because you are trying to access a second level of a one-level array.
