这两天在 Twitter 上看到一道题目，主要是考察 overload 和 type(of:) 的知识点，本文仅做记录，关于 MetaType 会单独写一篇文章来总结。 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 // Swift Quiz class
Library 和 Framework 的概念大家应该脑海里都有一些，本文旨在讲述下基本概念，没有对每个字节都了如指掌。关于基本的编译过程在 Build Process 一文中也大概讲述了一些。 在链接
编程语言的处理过程大致会有五个阶段，其每个阶段均有对应的工具： 预处理器 Preprocessor 编译器 Compiler 汇编器 Assembler 链接器 Linker 加载器 Loader 我们以一个简单的源文件，来看看具体这
