Array not counting objects in Swift

Question

Curious as to why this is not working?

@IBOutlet weak var counterLabel: UILabel! <-- Outlet/var


let array : [Int] = [1,2,3]

self.counterLabel.text = array.capacity

I am getting the error below and I was wondering anybody knew how to fix this? I am trying to get the text label to display the number of objects in the array.

Cannot assign a value of type 'Int' to a value of type 'String?'

You're setting a value of type String with a value of type Int so you need to convert the Int to a String:

self.counterLabel.text = String(array.count)

As commenters have mentioned, the property you're looking for is count

this won't solve the problem because he is accessing the wrong property. He should be using String(array.count)

I was using count but tried out capacity but I got a value of 4 with only 3 objects in the array. But that solution did work for me, I just replaced capacity with count.

Can also do "\(array.count)"
