Product:Swift Product Version:
Classification: Reproducible:
 
Summary:
You'd expect this to work:

var s = "Hello world"
println(s[0])

However, there is no built-in overload for subscript that takes an integer index.

This is a workaround but you'd expect something like this to be in the standard library:

extension String {
  subscript(i: Int) -> Character {
    return Array(self)[i]
  }
}

Steps to Reproduce:
Make a string.
Try to access a character at a specified index.

Expected Results:
Compiler gives an error.

Actual Results:
It returns a Character.
