Breaking
- The command-line parsing strategy for options that were delimited by a pipe or comma has changed. These options are now parsed as a space delimited list, e.g
--option "arg1" "arg2". - The option
--external-encodable-protocolsis deprecated, use--external-codable-protocolsinstead.
Enhancements
- Add experimental unused import analysis option
--enable-unused-import-analysis. - Add experimental automatic code removal option
--auto-remove. - Assign-only properties on structs with synthesized initializers are now detected.
- Added the
--retain-codable-propertiesoption to retain all properties on Codable types. - Results for redundant protocol conformances will now list the inherited protocols that should replace the redundant conformance, if any.
- Added the
--retain-filesoption to retain all declarations within the given files.
Bug Fixes
- Subscript functions required by
@dynamicMemberLookupare now retained. - A newline is no longer printed before non-Xcode formatted results.
--external-codable-protocolsnow retains enums that conform toCodingKey.- Fix public accessibility false-positive for actors.
- Fix public accessibility false-positive for property wrappers.
- Fix public accessibility false-positive for declarations referenced from a public
@inlinablefunction. - Fix public accessibility false-positive for function parameter default values.
- Fix public accessibility false-positive for inherited and default associated types.
- Fix public accessibility false-positive for generic types used in the generic argument clause of a return type.
- Fix public accessibility false-positive for retained/ignored declarations.
- Fix public accessibility false-positive for enum case parameter types.
- Fix public accessibility false-positive for properties initialized with generic specialized types.
- Types associated with assign-only properties are no longer identified as unused until the property is removed.
- Classes referenced in Info.plist as
NSPrincipalClassandWKExtensionDelegateClassNameare now retained.
