Learn the syntax used in Swift to access properties and call methods on type instances, and understand how the compiler interprets multiline blocks of code.
- [Narrator] Most programming languages use .notation…to call functions and access properties.…Objective-C is one exception which you may be…familiar with the bracket notation to call methods…on objects and it offers both .notation…and bracket notation to get and set properties.….notation is used exclusively in Swift.…I'm going to get into the details of all the code…you see here throughout the course.…But just to briefly walk through it, I have a couple of…structures to represent a car and a driver.…A car has a model property and a drive function…that prints "Vrooooom" when it's called.…
And a driver has a cars property, which is an array of cars.…I've created three car instances and an instance of driver…adding those three cars to its cars property.…Using .notation, I can access the car's property of Scott,…get the first car in the array, and that question mark…there is because a driver may not have any cars.…So the first one will not be there.…I'll go over that in more detail later in…the course, and I'll call drive on it.…
