ios - How to create a String with format?

Question

I need to create a String with format which can convert Int, Int64, Double, etc types into String. Using Objective-C, I can do it via below way:

NSString *str = [NSString stringWithFormat:@"%d , %f, %ld, %@", INT_VALUE, FLOAT_VALUE, DOUBLE_VALUE, STRING_VALUE];

How to do same with Wwift?

I think this could help you:

let timeNow = time(nil)
let aStr = String(format: "%@%x", "timeNow in hex: ", timeNow)
print(aStr)

Example result:

timeNow in hex: 5cdc9c8d
