Bug Fixes
- In Swift 5.3 and lower, all optional protocol members are now retained in order to workaround a Swift bug. This bug is resolved in Swift 5.4.
- Cases of public enums are now also retained when using
--retain-public. - Open method parameters are now also retained when using
--retain-public. - Empty public protocols that have an implementation in extensions are no longer identified as redundant.
- Foreign protocol method parameters are no longer identified as unused.
