Join Scott Gardner for an in-depth discussion in this video Understand access control, part of Swift 3 Essential Training: Beyond the Basics.
- [Instructor] Swift takes an innovative approach…to access control,…and a few additions and changes…have been made to access control in Swift 3.…Accesses controlled in Swift at three scopes.…Access control at the declaration level…determines the accessibility of a declaration,…or members inside a type definition,…such as it's properties, initializers and methods.…Although a source file may typically contain…only a single-type definition,…it is possible that multiple types…are defined in a single file.…File access control determines accessibility…of all declarations within a file.…
A module is a single unit of code distribution,…such as a built target of framework…that can be imported into another module.…Module access control determines accessibility…of anything declared within the entire module.…Access is controlled at five levels.…In order of least to most restrictive, they are…open, which applies only to classes,…public, internal, file-private and private.…I'll go over each of these.…Open applies only to classes and their members,…
