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

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_14_0, ios_17_0, tvos_17_0, maccatalyst_17_0, watchos_10_0, visionos_1_0;

About

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