在 Xcode 里下载文件真的是一种折磨, 特别是每次 Xcode 大版本更新都会遇到新的下载内容. 经过一翻周折, 本人找到一个方法可以轻松快速便捷地下载和安装对应的 Simulator 和 Doc 文件

1. 在 Mac 下, 打开 Xcode, 进入 Preference 中的 Downloads 面板
2. 点击任意的下载按钮
3. 打开系统帮助工具 Console
4. 稍等一会儿, 在 Xcode 里取消下载, 然后你会在 Console 里面看到对应的下载地址 (对应的 Cosnole Message 是 (DVTDownloadable: Download Cancelled. Downloadable: ...) 之类的)
5. 复制对应的链接地址, 到某雷或者任何比 Xcode 下载快的工具里
6. 等待下载完成, 进入 /Users/#{Username}/Library/Caches
