<p>集合（Set）是 Swift 集合类型（collection types）之一，集合用来存储类型相同且没有确定顺序唯一的值。你可以将集合想象成一盒台球：它们在颜色和数量上独一无二，但在盒内是无序的。</p>

<p>在计算机科学中，有很多问题可以通过将底层数据结构用优先级队列实现来改善算法的时间复杂度。其中 Dijkstra 的最短路径算法便是一个例子，该算法使用了优先级队列来在图中搜索两个顶点间的最短路径。</p>
<p>不幸的是，Swift 的标准库中并没有提供优先级队列的默认实现。所以我们将会研究如何自行实现基于堆的优先级队列。</p>

<p>作为 iOS 开发，我们十分清楚人们都喜欢互通性。我们喜欢通过无线设备与其他人进行沟通这一点是显而易见的。最近，我们开始希望能够与那些曾经被认为是独立的普通设备进行<em>通信</em>。我们开始喜欢，甚至是期望，部分无线设备可以收集并且分析自己的数据（通常称为“可穿戴设备”）。许多设备已经成为我们生活里的一部分，还为还有一个专门的术语来描述它：“Internet of Things” 或者 “IoT”（物联网）。现在地球上有数十亿的无线通讯设备。在这篇教程中，我们将聚焦 IoT 其中的一部分：蓝牙。 </p>
<p>我将说明蓝牙技术背后的基本概念，以及： </p>
<ul>
<li>展示如何精通蓝牙方向的软件开发，从而为你提供巨大的职业机遇 </li>
<li>提醒你必须去确认在发布一个使用蓝牙技术的应用时是否需要通过“资格审查” </li>
<li>给你提供 Apple 的<a href="https://developer.apple.com/documentation/corebluetooth" target="_blank" rel="noopener"><strong><em>Core Bluetooth</em></strong></a> 框架概述 (<a href="https://developer.apple.com/library/archive/documentation/NetworkingInternetWeb/Conceptual/CoreBluetooth_concepts/AboutCoreBluetooth/Introduction.html#//apple_ref/doc/uid/TP40013257-CH1-SW1" target="_blank" rel="noopener"><strong>也可以参阅这里</strong></a>) </li>
<li>最后，带领你使用 Swift 4 并通过 <em>Core Bluetooth</em> 和一个蓝牙设备来开发一款用于监控心率的 iOS 应用程序</li>
</ul>
<blockquote>
<p>提示：注意跟随阅读文章中包含的超链接。对于开发者这是重要的资料，它确保你完全理解蓝牙的工作方式以及苹果是如何支持蓝牙这种技术的。</p>

<p>在 Swift 中，协议中声明的属性没有访问控制的能力。如果协议中列出了某个属性，则必须使遵守协议的类型显式声明这些属性。 </p>
<p>不过有些时候，尽管你会在协议中声明一些属性，但你是要利用这些属性来提供你的实现，并不希望这些属性在类型的外部被使用。让我们看看如何解决这个问题。 </p>

<p>上个月，苹果公司 <a href="https://forums.swift.org/t/new-lsp-language-service-supporting-swift-and-c-family-languages-for-any-editor-and-platform/17024" target="_blank" rel="noopener">在 Swift.org 论坛上宣布</a>，正在着手为 Swift 和 C 语言支持 <a href="https://microsoft.github.io/language-server-protocol/" target="_blank" rel="noopener">Language Server Protocol</a>（语言服务器协议，LSP）。</p>
<blockquote>
<p>对于苹果公司而言，为所有 Swift 开发者 —— 包括非苹果平台上的 —— 提供高质量的工具支持非常重要。我们希望与开源社区合作，将精力集中在构建 Xcode 和其他编辑器、其他平台可以共享的公共基础设施上。为实现这一目标，[……]，我们决定支持 LSP。</p>

<p><strong>这可能是苹果自 2014 年将 Swift 作为开源软件发布以来，为 Swift 做出的最重要的决定。</strong> 这对于 APP 开发者来说是一件大事，对于其他平台上的 Swift 开发者来说更是一件大事。</p>
<p>为了理解其中的原因，本周的文章将研究 Language Server Protocol 解决了什么问题，它是如何工作的，以及它的长期影响可能是什么。</p>
