Swift – Function with Parameters
To define a function that can accept arguments, specify the parameters with respective types in the parenthesis of function definition.
The syntax to define a function with parameters is
func functionName(parameter1: <T>, parameter2: <T>) { //body }
Example
In the following example, we define a function add
that accepts two Int values and print their sum.
main.swift
func add(a: Int, b: Int) { let result = a + b print("The result is \(result)") } add(a: 4, b: 3)
