Tuples is a new concept that is introduced in swift programing. Tuples group the multiple values in a single compound value. It is not necessary that the each tuples value should have the same datatype. The datatype can be different and number of values can be added to the tuples.

let error=(0000,"Not Found");

Tuple groups together an Int and a String . Error is a collection of a number and a human readable string. It is described as a tuple of type (Int, String).

You can create tuples from any combination of datatype like (Int,Int,Bool) or (Bool,Int).

You can decompose a tuples content into separate constants or variables, which you then access as usual:

let (errorCode,errorMessage)=error
         println("value of the status\(errorCode) and message\(errorMessage)")

You can decompose the tuples values according to need if you want only to access the only errorCode or errorMessage then you can do like this

let (onlyErrorCode, _) = error
    println("The error code is \(onlyErrorCode)")
    // prints "The error code is 0000

Alternatively, access the individual element values in a tuple using index numbers starting at zero:

println("The Error code is \(error.0)")
    // prints "The Error code is 0000
    println("The Error message is \(error.1))
    // prints "The Error message is Not Found"
