哈哈。实际上，只要你稍微注意一下，就能以 Smalltalk 级别的封装和动态性，获得 C 语言级别的性能。参见《iOS and macOS Performance Tuning: Cocoa, Cocoa Touch, Objective-C, and Swift》：https://www.amazon.com/gp/product/0321842847/ref=as_li_tl?ie...
Ha ha. In fact, you can get C-level performance with Smalltalk levels of encapsulation and dynamicism if you pay just a little attention. See iOS and macOS Performance Tuning: Cocoa, Cocoa Touch, Objective-C, and Swift: https://www.amazon.com/gp/product/0321842847/ref=as_li_tl?ie...
……然而当程序的数据集增加到一百多条小记录（笔记/任务等）就出问题时，我们居然还觉得这很正常。总之，我在即将出版的新书《iOS and macOS Performance Tuning: Cocoa, Cocoa Touch, Objective-C, and Swift》[2]中写了更多关于这方面的内容 [1] http://sbel.wisc.edu/Courses/ME964/Literature/knuthProgrammi... [2] https://www.amazon.com/iOS-macOS-Performance-Tuning-Objectiv...
…yet we actually think it's OK that programs have problems when their data-sets increase to over a hundred small entries (notes/tasks/etc.). Anyway, I write a lot more about this in my upcoming book: "iOS and macOS Performance Tuning: Cocoa, Cocoa Touch, Objective-C, and Swift"[2] [1] http://sbel.wisc.edu/Courses/ME964/Literature/knuthProgrammi...

……Swift 大体上跟 Java 差不多，不过两者也各有几个优于或劣于对方的特例。Rust 胜过 Swift 的表现相当稳定，有时差距还相当大。当然，实际的 App 可能会有所不同。《iOS and macOS Performance Tuning》（https://www.amazon.com/iOS-macOS-Performance-Tuning-Objectiv...）这本书里，即便不搞任何刁钻的优化，Swift 对比 Objective-C 的基准测试结果也相当扎心（并非你最初……
…Swift is mostly equivalent to Java with a few outliers both for/against Swift. Rust outperforms Swift fairly consistently and sometimes quite considerably. Of course, real apps may be different. The book iOS and macOS Performance Tuning ( https://www.amazon.com/iOS-macOS-Performance-Tuning-Objectiv... ) has pretty damning benchmarks against Swift versus Objective-C even without using any tricky optimizations (not what you originally…

是的。比如，我是用 LaTeX 写完《iOS and macOS Performance Tuning: Cocoa, Cocoa Touch, Objective-C, and Swift》[1][2]的，我觉得成书效果相当不错（Pearson 有些非常厉害的 LaTeX 排版师，把我那些粗糙零碎的草稿变成了……

……以至于我能自己造一套框架。为什么？因为我尝试过真正去思考底层的数据结构，而不是凭条件反射遵循老规矩。最好的例子？Marcel Weiher 在《iOS and MacOS Performance Tuning》第 13 章里讲解了如何将一款公共交通 App 的查询速度提升 1000 倍。还有什么？对数据（代码）和应用（预期用途）的描述可能会好得多，因为思考……
