Append String in Swift

Question

I am new to iOS. I am currently studying iOS using Objective-C and Swift.

To append a string in Objective-C I am using following code:

 NSString *str         


        

Answer 1

Add this extension somewhere:

extension String {
    mutating func addString(str: String) {
        self = self + str
    }
}

Then you can call it like:

var str1 = "hi"
var str2 = " my name is"
str1.addString(str2)
println(str1) //hi my name is

A lot of good Swift extensions like this are in my repo here, check them out: https://github.com/goktugyil/EZSwiftExtensions
