Structures is used to represent a collection of different types. In swift, it is possible to have initializers and methods like classes. The most common difference is that class instance is passed as reference and structure is passed as copy.

struct structureName{
   //variables and methods
// Structure initialization
let variableName = structureName(variable1:initialValue1,...,variablen:initialValuen)


struct Student{
var name:String
var rollNo:String
func desc()->String{
return "The name of student with roll number\(rollNo) is \(name)"
