Swift 2.1- tabBarController!.selectedIndex return massive integer

Question

I am needing to put the tabBarController!.selectedIndex number inside a constant.

I am expecting a number between 0 and 3 depending on what tab I choose, but instead I get numbers like 2147483647

Any ideas why this is?

The code is:

let selectedTab = tabBarController!.selectedIndex
print(selectedTab)

Answer 1

That value is NSNotFound. In this case it seems to represent "no selection".
