• TypeIndexing module becomes optional (available after macOS 13.0), backporting the main library to macOS 10.15

What's Changed

This update brings the ability to generate swiftinterface

What's Changed

• Fixed the issue of symbol confusion with Protocols and Protocol Conformances. The cause was that the Swift compiler optimizes by storing different symbols with the same implementation at the same offset/address, commonly seen in default implementations of some conformances.

• By traversing the symbol table, it is now possible to dump computed properties and static computed properties of types, as well as functions and static functions excluding the class virtual table.

• Fixed the issue of nominal type generic parameter errors. For nominal types with a parent type, the generic context's params and requirements carry all the parent's params and requirements. For example: Ancestor<A, B>.Parent<A1, B1>.Current. Previous versions would define Ancestor's A, B and Parent's A1, B1 together in Current. The new version corrects this issue and adds the correct generic parameter depth.

Full Changelog: 0.4.1...0.5.0

• Fixed an issue where demangle might fail for iOS 26 MachO files

• Now if a demangle type fails, an error message will be printed without terminating the program

• Added a new interface DemangleOptions, the printed information is closer to swift-interface

Added CLI for MachOSwiftSection
