Program Objective-C

1 - A Program in Objective C Method Function Declaration, Definition With Calling.

#import <Foundation/Foundation.h>

}
return result;
}
@end

//Variable declaration
int a;
int b;
int main()

//Variable defination

Object Oriented Programming Feature in Swift

Classes and Objects

Create A Class 

Class A{
//Empty Class
}
Create a new instance new Object in a Class A
Class A{
var new = A()
}

Properties 

Class B{

var data: Int = 10

}
