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

I had to get initials from first and last names, and join them together. Using bits and pieces of the above answers, this worked for me:

  var initial: String = ""

            if !givenName.isEmpty {
                let char = (givenName as NSString).substring(with: NSMakeRange(0, 1))
               let str = String(char)
                initial.append(str)
            }

            if !familyName.isEmpty {
                 let char = (familyName as NSString).substring(with: NSMakeRange(0, 1))
                let str = String(char)
                initial.append(str)
            }
