Access control lets you specify what data inside structs and classes should be exposed to the outside world, and you get to choose four modifiers:
Most of the time you don't need to specify access control, but sometimes you'll want to explicitly set a property to be private because it stops others from accessing it directly. This is useful because your own methods can work with that property, but others can't, thus forcing them to go through your code to perform certain actions.
To declare a property private, just do this:
class TaylorFan {
private var name: String?
}
If you want to use “file private” access control, just write it as one word like so: fileprivate
.
