Anycan holdanystruct, enum, tuple, or other Swift type you can define in the language. The Objective-C bridge in Swift 3 can in turn present any Swift value as anid-compatible object to Objective-C. This makes it much easier to store custom Swift value types in Cocoa containers,userInfo...

Preface 结果生成器(以前叫做函数生成器)是swift5.4中引入的一项新feature,它是SwiftUI中支持ViewBuilder的技术。随着Xcode12.5的发布(目前处于beta测试阶段),苹果正式向开发者开放了它,允许我们为各种用例创建自己的自定义结果生成器。 本文讲讲解结果生成器的基本概念、工作原理以及如何使用它来创建自己的自定义结果生成器。
Every programming language has a set of conventions that people come to expect. Learn about the patterns that are common to Swift API design, with examples from new APIs like SwiftUI, Combine, and RealityKit. Whether you're developing an app as part of a team, or you're publishing a libra...

This era started with the debut of the C programming language. In the early days of programming, people went a bit over the top using functions for everything they could possibly think of. This led to very modular but very hard-to-read programs. ...
objdump: Dump object files. Some examples of usingobjdumpare documented in the previous subsection. If you have a Swift compiler build, you can usellvm-objdumpfrom$LLVM_BUILD_DIR/bininstead of using the systemobjdump. Compared to other tools on this list,objdumppacks a LOT of functionality; it...
How to run XLForm examplesClone the repository git@github.com:xmartlabs/XLForm.git. Optionally you can fork the repository and clone it from your own github account, this approach would be better in case you want to contribute. Move to either the Objective-c or Swift example folder. Install...
