Swift 5.9 之前 Swift 与 C++ 互操作需要借助于 Objective-C,即 Swift ↔ Objective-C ↔ C++。 Swift 5.9 之后 Swift 与 C++ 的类型与函数有了可以直接交互的能力。 重要配置:Build Settings —> Swift Complier - Language —> C++ and Objective-C Interoperability —> 选择 C++/Objective-C++。 Swift...
互通性[interoperability]可以让Swift类拥有许多Objective-C的特性,Swift类可以继承Objective-C类,遵循Objective-C协议,也能利用其他的Objective-C特性。 2.继承Objective-C的类 和普通继承语法一样,在类名后面用冒号运算符继承Objective-C的类。可以获取Objective-C超类中的所有功能,也可以通过重写[override]给出超类方...
Objective-C and C++ interoperability What’s new Swift 6 makes it easier to write concurrent code correctly with a new, optional language mode that analyzes your code at compile-time and diagnoses possible data races. This release also brings other enhancements to concurrency and generics, as we...
互通性[Interoperability]指的是Swift和Objective-C之间相互的调用。互通性的一个方面就是使用Swift代码来调用Objective-C的API[Application Programming Interface],在import了Objective-C的框架[framework]后,我们可以使用Swift语法实例化它的类以及完成类的各种交互。 2.初始化 Objective-C使用init方法来实例化一个类,Obj...
前文《百度App Objective-C/Swift 组件化混编之路(二)- 工程化》 已经介绍了百度App 组件内 Objective-C/Swift 混编、单测、以及组件间依赖、二进制发布、集成的工程化过程。下面重点介绍百度App 组件化 Objective-C/Swift 组件化混编改造实践,希望能对大家有所启发和帮助。

I find that the NSNotification.Name NEVPNStatusDidChange is not visible when the Swift Compiler setting: C++ and Objective-C Interoperability is set to C++/Objective-C++. Simply switching between C/Objective-C and C++/Objective-C++, a successfully building app is no longer able to build with ...
CMake also generates the 'Swift Compiler - Custom Flags' for each debug/release mode, and they all look like so: '-cxx-interoperability-mode=default' -Xcc '-std=c++20' $(inherited) (modulo the -O options for size/none/etc). So I'm confused what flags Xcode 15 Beta is using when...
