iOS Swift 2.0 Collections and Control Flow Control Flow With Loops For In Loops


I don't understand the challenge at all.

What challange is it?

1 Answer

A for in loop is a simple enumeration, if you have worked in Javascript or PHP before you would know this as a foreach loop quite simply it will loop through a collection from the first index until the last.

Therefore if you have your array with 10 values it would read something like this

var results : [Int] = [1,2,3,4,5,6,7,8,9,10];

for index in results
  print("The value is: \(index)");

I suggest having a read through here; https://developer.apple.com/library/ios/documentation/Swift/Conceptual/Swift_Programming_Language/ControlFlow.html

As this is really a fundamental aspect of collection's. Hope this helps.

The only other thing I've used is Python but I still don't really get for in loops.
