Stay tuned! [ 15 ] Advanced Swift Now, you have got some experience in the Swift programming language and have seen how funny and easy to learn it is. In this chapter, we will take you to the next level in Swift. We will talk about more advanced topics in Swift. For sure, we can't cover all topics in Swift, but we selected the most important and commonly used ones. Type casting and type checking Type casting and checking are ways used in Swift to check the type of instances and cast them to any different type.

To do this, you can type {get set} after property declaration. canFly = true //Compile error As you have seen in previous protocol, we defined two types of properties: readonly and settable one. The Bicycle class conforms to the protocol, so it has to define the properties that are defined in the VehicleProtocol protocol with the same property name and type. We set the value of the read-only canFly property in class declarations where instances can't change it. You will receive a compile error if you try to set this variable.

It takes two parameters, lhs and rhs, which means the left-hand side and right-hand side of the equation is a summation. The function returns a point, which is the sum of the two points. Then, in the code, we wrote p1 + p2. This code will call the + function that accepts two points and returns their sum. It makes your code very clean and readable. y) } let p1 = CGPoint(x: 1, y: 4) let p2 = CGPoint(x: 5, y: 2) let p4 = p2 - p1 //{x 4 y -2} It's very straightforward and done in the same way of addition.
