About this Episode
There's been a much stronger focus on calling ObjC from Swift than the other way around, but in this talk we'll cover both directions and the parts of the Swift language involved in the process.
ObjC Interop Overview
- Nikita Lutsenko's talk: https://realm.io/news/altconf-nikita-lutsenko-objc-swift-interoperability/
- NS_SWIFT_NAME
- NS_SWIFT_UNAVAILABLE
- NS_REFINED_FOR_SWIFT
- NS_SWIFT_NOTHROW
- NS_NOESCAPE
- NSEXTENSIBLESTRING_ENUM
- Nullability Annotations
- Generic Annotations
- ClangImporter (omit needless words logic lives here)
- PrintAsObjC
- Kevin Ballard's PR to include unavailable/deprecated/availability attributes: https://github.com/apple/swift/pull/6480
- ObjC codegen via string manipulation. Very hackable.
