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

append append(c: Character) IS the right method but your code has two other problems.

The first is that to iterate over the characters of a string you must access the String.characters property.

The second is that the append method doesn't return anything so you should remove the newStr.

The code then looks like this:

for aCharacter : Character in aString.characters {
    var str:String = ""
    str.append(aCharacter)
    // ... do other stuff
}
