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

SWIFT 2.x

let extendedURLString = urlString.stringByAppendingString("&requireslogin=true")

SWIFT 3.0

From Documentation: "You can append a Character value to a String variable with the String type’s append() method:" so we cannot use append for Strings.

urlString += "&requireslogin=true"

"+" Operator works in both versions

let extendedURLString = urlString+"&requireslogin=true"
