Swift & the Objective-C Runtime - NSHipster

http://nshipster.com/swift-objc-runtime

Even when written without a single line of Objective-C code, every Swift app executes inside the Objective-C runtime, opening up a world of dynamic dispatch and associated runtime manipulation. To be sure, this may not always be the case Swift-only frameworks, whenever they come, may lead to a Swift-only runtime. But as long as the Objective-C runtime is with us, let’s use it to its fullest potential. Come to the rescue. For example, to add a.

Swift Documentation - NSHipster

http://nshipster.com/swift-documentation

Written by Mattt Thompson. Code structure and organization is a matter of pride for developers. Clear and consistent code signifies clear and consistent thought. Even though the compiler lacks a discerning palate when it comes to naming, whitespace, or documentation, it makes all of the difference for human collaborators. Readers of NSHipster will no doubt remember the article about documentation published last year. Let’s dive in. Since the early 00’s, Headerdoc. You’ve seen this in action). Parameter b...

NSScanner - NSHipster

Written by Nate Cook. Strings are a ubiquitous and diverse part of our computing lives. They comprise emails and essays, poems and novels and indeed, every article on nshipster.com. The configuration files that shape the site, and the code that builds it. Great for splitting a string into constituent pieces. Not so great at anything else. Powerful for validating and extracting string data from an expected format. Cumbersome when dealing with complex serial input and finicky for parsing numeric values.

NSCalendar Additions - NSHipster

吗 你有指定正确的日历单元吗 你的代码在 2100 年 2 月 28 号还能正常工作么. 除非你跑去考察版本说明和 API 变动表，不然你肯定不会知道最近发布的几个 OS X 版本里，. Calendar.isDate(tuesday, equalToDate: thursday, toUnitGranularity: .CalendarUnitWeekOfYear). 会给你返回 11 00， 而不是 11 59， 虽然在反向搜索中 11 59 严格意义上来讲是比 11 00 早。 或者搜索时遇到类似 2 月 或者 4 月 31 号，它都能帮我们跳过这些缺失的时间。 2015 年情人节，早上 9 点. 为了找到月的最后一天， 我设置一个日期组件然后把 `day` 设成 31.

本周将关注 Swift 1.2 版本的一个. 本次发布的每一个小更新都带来了巨大的好处 增量构建、丰富了 Xcode 中的错误信息、提升 Xcode 稳定性、静态类属性、支持 C 的 union 和 bitfield、将 Swift 中的. Swift 1.2 允许通过多值并行 optional 绑定来避免. A b) / c = ( a b) / c). A b) / c = ( a b) / c). 只有在所有的 optional binding 都成功的情况下才会进行. 让我们回顾一个经典的例子，将 这样一个庞大的 JSON 块. 在 Swift 1.2 中解析。 Load and parse the JSON into an array. 在 Swift 第一版发布的时候，每一个对 Cocoa API 的调用方法都会返回一个模糊解析的 optional 类型 比如说. Swift 确实能够调用 Cocoa API 了，但调用方法长得真奇怪。 这种情况不复存在了 Swift 1.2 带来了新版本的 Clang。 它们在 Swift 中会以 optional 值表示 比如.
