Pure Swift:对于 Apple 工程师来说,可以直接在系统框架使用 Swift,而不必用 Objective-C 来 wrap 一遍,运行效率更高,维护成本更低。得益于 ABI 稳定,在 2019 年,Apple 也确实推出了 SwiftUI、RealityKit、Combine、CreateML 4个 Pure Swift 框架。 1.3 Module 稳定 Swift 库和库的 API 以 module 的方式导出,...
because Swift-defined value types can be passed to Objective-C APIs and extracted as Swift types, eliminating the need for manual “box” types. These benefits also extend to collections: Objective-C collection typesNSArray,NSDictionary, andNSSet, which previously only accepted elements ofAnyObject...
This article explores Swift and Objective-C, comparing the features and differences of the two iOS languages.

Swift 是苹果新推出的编程语言,专门针对 OS X 和 iOS 的应用开发。Swift 在各个方面优于 Objective-C,也不会有那么多复杂的符号和表达式。同时,Swift 更加快速、便利、高效、安全。除此之外,新的 Swift 语言依旧会与 Object-C 相兼容。展开收起 暂无标签 ...
building iOS and OSX applications. Swift is a modern language with the power of Objective-C without the "baggage of C." While we can't argue that Objective-C has it's difficulties being tied closely to C, but the real question is... How does Swift compare to a modern language like ...
