Submitted by Nidhi, on July 01, 2021

Problem Solution:

Here, we will create a structure with two methods to set and print structure members.

Program/Source Code:

The source code to create methods within a structure is given below. The given program is compiled and executed successfully.

// Swift program to create methods within a structure

import Swift

struct Student {
    var id: Int=0
    var name:String=""
    var fees:Int=0

    mutating func setInfo(i:Int, n:String, f:Int) {
        id=i
        name=n
        fees=f
    }

    mutating func printInfo() {
        print("Student Information:")
        print("\tStudent Id  : ",id)
        print("\tStudent Name: ",name)
        print("\tStudent Fees: ",fees)
    }
}

var stu = Student()

stu.setInfo(i:1001,n:"Rahul",f:8000)

stu.printInfo()

Output:

Student Information:
        Student Id  :  1001
        Student Name:  Rahul
        Student Fees:  8000

...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 a structure Student with three fields id, name, and fees and created two methods setInfo() and printInfo(). The setInfo() method is used to set student information and printInfo() method is used to print student information on the console screen.

Then we created the structure variable stu and set the student information using the setInfo() method. After that, we printed the student information using the printInfo() method on the console screen.
