Here, we are going to learn how to implement function overloading based on the different number of arguments in Swift programming language?
Submitted by Nidhi, on July 04, 2021

Problem Solution:

Here, we will create two functions with the same name but different number of arguments to implement function overloading.

Program/Source Code:

The source code to implement function overloading based on the different number of arguments is given below. The given program is compiled and executed successfully.

// Swift program to implement function overloading 
// based on the different number of arguments

import Swift

func AddNum(n1:Int,n2:Int){
    var result:Int = 0

    result = n1 + n2
    
    print("Addition is: ",result)
}

func AddNum(n1:Int,n2:Int,n3:Int){
    var result:Int = 0

    result = n1 + n2 + n3
    
    print("Addition is: ",result)
}

AddNum(n1:10,n2:20)
AddNum(n1:10,n2:20,n3:30)

Output:

Addition is:  30
Addition is:  60

...Program finished with exit code 0
Press ENTER to exit console.

Explanation:

In the above program, we imported a package Swift to use the print() function using the below statement,

import Swift

Here, we created two AddNum() functions with a different number of arguments to implement function overloading. Then we called both functions with some values and printed the result on the console screen.
