How to create a string with format?

Question

I need to create a string with format which can convert int, long, double etc. types into string. Using Obj-C, I can do it via below way.

NSString *str = [NS         


        

Answer 1

First read Official documentation for Swift language.

Answer should be

var str = "\(INT_VALUE) , \(FLOAT_VALUE) , \(DOUBLE_VALUE), \(STRING_VALUE)"
println(str)

Here

1) Any floating point value by default double

EX.
 var myVal = 5.2 // its double by default;

-> If you want to display floating point value then you need to explicitly define such like a

 EX.
     var myVal:Float = 5.2 // now its float value;

This is far more clear.
