Cidre (French Cidr) - Rusty Apple API's

Goals

  • Performance
  • Zero cost objc interop
  • No legacy platforms support
  • ML friendly
  • Rusty API (ObjC and C)
  • API Availability checks
  • Buttle tested in own apps. (StreamChamp.app for recording, Yoml to be released)

Performance

  • Developer can finish critical path without deallocations.
  • Zero cost selectors calls (XCode 14.3) WWDC video 3:10
  • Integrated async blocks
  • Zero cost Apple's C API interfaces
  • Static cf::String and ns::String refs (ns::str!(c"hello"))

Platforms

  • macOS
  • iOS/iPadOS
  • tvOS
  • watchOS
  • visionOS

Versioning (API Availability)

Deployment targets are controlled via features macos_x_x, ios_x_x, tvos_x_x, watchos_x_x, visionos_x_x. If selector is not defined in deployment target it becomes unsafe. So developer should check if object responses to that selector before call it.

Default features: macos_15_0, ios_18_0, tvos_18_0, maccatalyst_18_0, watchos_11_0, visionos_2_0;

About

This is personal research project. With this project I learn Apple SDK's and rust.
