GitHud的下载地址是：/jdg/MBProgressHUD/
下载完成后，将MBProgressHUD.h和MBProgressHUD.m拖入已经新建好的Swift项目。因为使用的swift语言，所以拖入项目的时候会提示是否新建一个桥接objective-c与swift的文件，选择是即可。此步骤会自动新建一个文件。如图：
在该文件（MBProgressHUDDemo-Bridging-Header.h）中，有这样的一句注释：
// Use this file to impZ喎�"/kf/ware/vc/" target="_blank" class="keylink">vcnQgeW91ciB0YXJnZXQmcnNxdW87cyBwdWJsaWMgaGVhZGVycyB0aGF0IHlvdSB3b3VsZCBsaWtlIHRvIGV4cG9zZSB0byBTd2lmdC48L3A+DQo8cD7S4su806a4w8rHtbzI6823zsS8/qOsyrm1w8TjtcRzd2lmdL/J0tTKudPDzc+9+MiltcTOxLz+oaM8YnIgLz4NCtLytMujrNTauMPOxLz+1tDQtNXiw7TSu77ko7o8L3A+DQo8cHJlIGNsYXNzPQ=="brush:java;">#import "MBProgressHUD.h"

会发现在Build Settings–>Swift complier -Code Generation中，多了一个项，个人理解是桥接文件MBProgressHUDDemo-Bridging-Header.h的声明。如果有不同见解，欢迎指正。如图：
尝试了几种样式的提示框。使用按键来触发。
以下是整个Demo的代码：

以下是运行的效果：
