I am getting the following error when I am running my code in Xcode7 with Swift2, after presenting a view controller through a push segue:
当我在 Xcode7 和 Swift2 中运行我的代码时，我收到以下错误，在通过 push segue 呈现视图控制器后：

Although this problem seems to persist as a bug and will likely be fixed, it stems from the new App Transport Securitythat has been implemented in iOS 9.
虽然这个问题似乎作为一个错误持续存在并且很可能会得到修复，但它源于iOS 9 中实施的新App Transport Security。
If your application pulls data from a web server, in order to populate the View Controller that you will be presenting, you can resolve these errorsby verifying/granting access to the particular site(s) you're pulling from.
如果您的应用程序从 Web 服务器拉取数据，为了填充您将呈现的视图控制器，您可以通过验证/授予对您从其拉取的特定站点的访问权限来解决这些错误。
In order to address this you will add the following to your App's .plist file:
为了解决这个问题，您需要将以下内容添加到您的应用程序的 .plist 文件中：
You may want to alter your ATS Exception Dictionaryto fit your needs
<key>NSAppTransportSecurity</key> <dict> <key>NSExceptionDomains</key> <dict> <key>testdomain.com</key> <dict> <key>NSIncludesSubdomains</key> <false/> <key>NSExceptionAllowsInsecureHTTPLoads</key> <false/> <key>NSExceptionRequiresForwardSecrecy</key> <true/> <key>NSExceptionMinimumTLSVersion</key> <string>TLSv1.2</string> <key>NSThirdPartyExceptionAllowsInsecureHTTPLoads</key> <false/> <key>NSThirdPartyExceptionRequiresForwardSecrecy</key> <true/> <key>NSThirdPartyExceptionMinimumTLSVersion</key> <string>TLSv1.2</string> <key>NSRequiresCertificateTransparency</key> <false/> </dict> </dict> </dict>
您可能想要更改您的ATS 例外词典以满足您的需要
<key>NSAppTransportSecurity</key> <dict> <key>NSExceptionDomains</key> <dict> <key>testdomain.com</key> <dict> <key>NSIncludesSubdomains</key> <false/> <key>NSExceptionAllowsInsecureHTTPLoads</key> <false/> <key>NSExceptionRequiresForwardSecrecy</key> <true/> <key>NSExceptionMinimumTLSVersion</key> <string>TLSv1.2</string> <key>NSThirdPartyExceptionAllowsInsecureHTTPLoads</key> <false/> <key>NSThirdPartyExceptionRequiresForwardSecrecy</key> <true/> <key>NSThirdPartyExceptionMinimumTLSVersion</key> <string>TLSv1.2</string> <key>NSRequiresCertificateTransparency</key> <false/> </dict> </dict> </dict>
More details to this solution can be found hereor hereThe Apple Documentation for App Transport Securityis worth reading too.

I had the same two error messages. In my case, the errors were appearing when I called [[UIApplication sharedApplication] openURL:url]after the user selected a button in an open UIAlertController. I assumed the alert was trying to close at the same time I was trying to open the URL. So, I introduced a slight delay and the error message went away.
我有相同的两条错误消息。在我的情况下，当我[[UIApplication sharedApplication] openURL:url]在用户选择一个打开的按钮后调用时出现错误UIAlertController。我假设警报试图在我尝试打开 URL 的同时关闭。所以，我引入了一个轻微的延迟，错误信息消失了。
dispatch_after(0.2, dispatch_get_main_queue(), ^{
[[UIApplication sharedApplication] openURL:url];
});
Not sure if this helps with your particular problem, but I thought it might be helpful to share.
不确定这是否有助于解决您的特定问题，但我认为分享可能会有所帮助。

Dismissing view controller prematurely might cause this.
过早关闭视图控制器可能会导致这种情况。
[self dismissViewControllerAnimated:YES completion:NULL];
//<do something..>
This throws _BSMachErrors
这会抛出 _BSMachErrors
vs
对比
//<do something..>
[self dismissViewControllerAnimated:YES completion:NULL];
Now, the _BSMachError is gone.
现在，_BSMachError 消失了。

I got these errors when I was using the keyboard. According to this note in Apple Docs, this is somewhat expected.
我在使用键盘时遇到了这些错误。根据 Apple Docs 中的这个说明，这在某种程度上是预料之中的。

Having this statement right below IBAction Button was causing the issue.
在 IBAction Button 正下方有此声明导致了问题。
self.view.endEditing(true)
The issue was fixed in Swift 3, by commenting out the above line and handling the end editing in a different way, or can also be fixed adding the above line after all other code under IBAction.
该问题已在 Swift 3 中修复，通过注释掉上面的行并以不同的方式处理结束编辑，或者也可以在 IBAction 下的所有其他代码之后添加上面的行来修复。

I had this problem while debugging and it disappeared when I removed a breakpoint in my response to the view size changing.
我在调试时遇到了这个问题，当我在响应视图大小更改时删除断点时它消失了。
