I have this code

var i = 1
println(i) //result is 1   
println(%02i) //is wrong

I want it to output 01 instead of 1

Your best bet is still going to be NSString formatting:

var i = 3
println("someInt is now \(i)")
// prints "someInt is now 1"
println(NSString(format:"%.2f",i))
// prints "someInt is now 01"

May be this help you.

Unfortunately, you can't format swift strings like that (as far as I know.) You can try to use an NSString though.

println(NSString(format:"%02i", i))

var i = 1
println("0\(i)")

//01

This is it

var i = 1
 NSLog("%02d", i)

O/P - 01
