How to append a character to a string in Swift?

Question

This used to work in Xcode 6: Beta 5. Now I\'m getting a compilation error in Beta 6.

for aCharacter: Character in aString {
    var str: String = \"\"
    v         


        

Answer 1

Another possible option is

var s: String = ""
var c: Character = "c"
s += "\(c)"
