Swift version: 5.6
These two forms of access control are similar, but there are two differences.
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.
In practice you’re likely to see private
used significantly more than fileprivate
.
