In storyboard below the Custom Class field the module is set to None. Change that to your app module or just remove and enter class again, it should set to default like this:

在自定义类字段下方的故事板中，模块设置为无。将其更改为您的应用程序模块或只是删除并再次输入类，它应该设置为默认值，如下所示：

For me the problem was that the class was not part of the Target Membership. Just add the class to the target, and you should see it back on the interface builder.

对我来说，问题是该类不是Target Membership. 只需将类添加到目标，您应该会在界面构建器上看到它。

Still seeing this problem with XCode 8.2.1, but I am able to fix the problem by modify these in the storyboard xml file:

仍然在XCode 8.2.1 上看到这个问题，但我可以通过在 storyboard xml 文件中修改这些来解决这个问题：

1. Delete customModuleProvider="target"in the viewControllertag:

   - <viewController ... customModule="Flights" customModuleProvider="target" sceneMemberID="viewController">
   + <viewController ... customModule="Flights" sceneMemberID="viewController">
   

2. Delete customModule="Flights" customModuleProvider="target"in the widget tag (in my case, a labeltag):

   - <label ... translatesAutoresizingMaskIntoConstraints="NO" id="PzF-6K-Hpi" customClass="YZLabel" customModule="Flights" customModuleProvider="target">
   + <label ... translatesAutoresizingMaskIntoConstraints="NO" id="PzF-6K-Hpi" customClass="YZLabel">
   

1. customModuleProvider="target"在viewController标签中删除：

   - <viewController ... customModule="Flights" customModuleProvider="target" sceneMemberID="viewController">
   + <viewController ... customModule="Flights" sceneMemberID="viewController">
   

2. customModule="Flights" customModuleProvider="target"在小部件标签中删除（在我的例子中，是一个标签标签）：

   - <label ... translatesAutoresizingMaskIntoConstraints="NO" id="PzF-6K-Hpi" customClass="YZLabel" customModule="Flights" customModuleProvider="target">
   + <label ... translatesAutoresizingMaskIntoConstraints="NO" id="PzF-6K-Hpi" customClass="YZLabel">
   

I find that step 1 is very important too to resolve the crash/warning and cannot be skipped.

我发现第 1 步对于解决崩溃/警告也非常重要，不能跳过。

I resolved a similar issue by adding '-ObjC' to 'Other linker flags' in the 'Build Settings' of my project.

我通过在我的项目的“构建设置”中将“-ObjC”添加到“其他链接器标志”来解决了类似的问题。

i had a similar issue as well. I had a ViewController with a TableView in it, and the tableView's custom class was called 'ViewController'. I just deleted the custom class for the tableView and the error went away.

我也有类似的问题。我有一个带有 TableView 的 ViewController，tableView 的自定义类被称为“ViewController”。我刚刚删除了 tableView 的自定义类，错误就消失了。

I solved it by manually writing the module name in the storyboard, under the class name. In my case it was the same name as the class, but it may differ.

我通过在故事板中的类名下手动编写模块名称来解决它。就我而言，它与类同名，但可能不同。

For me: for table view cell in 'Indentity Inspector' unchecked 'Inherit Module From Target' and cleaned the project. It solved the problem and project run successfully

对我来说：对于“身份检查器”中的表格视图单元格，取消选中“从目标继承模块”并清理项目。问题解决，项目运行成功

I resolved this issue by applying view controller initialise. View-controller basic declaration of view did load method and class implementation in *.swift class shows in storyboard.

我通过应用视图控制器初始化解决了这个问题。视图的视图控制器基本声明在故事板中显示了 *.swift 类中的加载方法和类实现。
