Subsequently, one may also ask, what is Fileprivate?

fileprivate is one of the new Swift 3 access modifiers that replaces private in its meaning. fileprivate defines an entity (class, extension, property, ) as private to everybody outside the source file it is declared in, but accessible to all entities in that source file.

Also Know, what is module in Swift? A module is a single unit of code distribution—a framework or application that is built and shipped as a single unit and that can be imported by another module with Swift's import keyword. Each build target (such as an app bundle or framework) in Xcode is treated as a separate module in Swift.

Consequently, what is file private in Swift?

If you mark something fileprivate it can be read anywhere in the same file it was declared – even outside the type. On the other hand, a private property can only be read inside the type that declared it, or inside extensions to that type that were created in the same file.

What is Open Class in Swift?

In short: An open class is accessible and subclassable outside of the defining module. An open class member is accessible and overridable outside of the defining module. A public class is accessible but not subclassable outside of the defining module.
