> Key: THRIFT-3773
> URL: https://issues.apache.org/jira/browse/THRIFT-3773
> Project: Thrift
> Issue Type: New Feature
> Components: Swift - Library
> Reporter: Thomas Bartelmess
>
> We already have the option to generate Swift code in the Cocoa compiler,
> however large parts of the (Objective-C) Cocoa Library still depend on Cocoa
> and Objective-C.
> It would be good to have a native Swift library that doesn't depend on the
> Cocoa libraries.
> Design goals:
> - Fully compatible with the code that is currently generated by the Cocoa
> compiler (both Objective-C and Swift).
> - Ability to run on Linux
> - Pure Swift, no Objective-C code.
> - No dependencies on closed source apple libraries
> - Keep the same interface, so that the library is compatible with the code
> the current cocoa compiler generates
> - Better server support that the current Objective-C library.
> - Follow the new Swift packaging format to be compatible with the Swift
> Package manager
