Array values not showing up in custom table cell - ios

Question

I am making a simple weather app and my table view is supposed to show the weeks forecast by showing the day on the left side and the high temp on the right side. My cellForRowAtIndexpath is below. It correctly displays the dayarray in my custom daylabel but the maxarray which contains max temperatures doesn't show up. When I print out the max array values it looks correct and all the numbers are listed there but still does not show up. If I just hard code a value in that text label like "Test" then that will show up but the array doesn't.
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! DailyWeatherTableViewCell
cell.daylabel.text = dayarray[indexPath.row] as? String
cell.maxlabel.text = maxarray[indexPath.row] as? String
return cell
UPDATE: My array is set up like this:
dayarray = [dateString1,dateString2, dateString3, dateString4, dateString5, dateString6, dateString7]
maxarray = [max1int, max2int, max3int, max4int, max5int, max6int, max7int]
Its kind of complicated where these values come from but if I print out maxarray, it looks like this:
100
100
92
90
90
89
89

I think the way you cast the Int to String cause the value to nil. Try change to below instead:
cell.maxlabel.text = String(maxarray[indexPath.row])
The different is that String() is create an object of string from the Int value. while the as? operator normally used when you have different type of objects in your array and you want to cast it to specific type. for example
let arr = [1, 21, 3, 5, "Hello world", 1, 2, "food"]
for element in arr {
if let stringValue = element as? String {
print(stringValue)
}
else if let intValue = element as? Int {
print (intValue)
}
}
