In Swift, access control is an important feature that helps manage the visibility and accessibility of code components across different modules and packages. The access levels in Swift include private, internal, package, and public.
- Private: Accessible only within the same file.
- Internal: Accessible within the same module.
- Package: Accessible from other modules in the same package.
- Public: Accessible from any other module.
When you don't specify an access level, Swift implicitly uses internal. The package access level is particularly useful when you want to share code between modules within the same package but not expose it to external modules. This is especially relevant when working with binary frameworks, as it allows for a more controlled exposure of APIs.
For more details on Swift's access control and package management, you can refer to the session A Swift Tour: Explore Swift’s features and design (10:59).
