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

 let original:String = "Hello"
 var firstCha = original[original.startIndex...original.startIndex]

 var str = "123456789"
 let x = (str as NSString).substringWithRange(NSMakeRange(0, 4))

 var appendString1 = "\(firstCha)\(x)" as String!
 // final name
 var namestr = "yogesh"
 var appendString2 = "\(namestr) (\(appendString1))" as String!*
