Xcode 8 - IB Designables - Failed to render and update auto layout status, The agent crashed

提问by Alan

I recently upgraded to Xcode 8 and I am having issues with the Storyboard.

我最近升级到 Xcode 8，但故事板有问题。

If I open the project and I don't have the Storyboard open, it will compile and run just fine. Once I open up the Storyboard, I get multiple errors about IB Designables as shown below.

如果我打开项目并且我没有打开 Storyboard，它会编译并运行得很好。打开 Storyboard 后，我收到多个关于 IB Designables 的错误，如下所示。

These views are the only views that are using custom views from TextFieldEffectsand BEMCheckboxthat I imported using Cocoapods.

这些视图是唯一使用自定义视图TextFieldEffects并且BEMCheckbox我使用 Cocoapods 导入的视图。

You can try one of the following to figure out the cause:

您可以尝试以下方法之一找出原因：

1. look for the IBDesignablesAgentCocoaTouchlogs in this directory: ~/Library/Logs/DiagnosticReportsand see the cause.

1. IBDesignablesAgentCocoaTouch在此目录中查找日志： ~/Library/Logs/DiagnosticReports并查看原因。

Note: for user with Catalina: look for IBDesignablesAgent-iOS_<DATE>-<MAC_NAME>.crash

注意：对于使用 Catalina 的用户：查找 IBDesignablesAgent-iOS_<DATE>-<MAC_NAME>.crash

1. Go to the Editor -> Debug Selected View while selecting your @IBDesignable UIViewin your storyboard, and see the stack trace.

2. Delete Derive Data folder.

   Xcode Preference -> Location -> Derived Data
   /Users/YourMacName/Library/Developer/Xcode/DerivedData
   

3. Clean your project Shift+Command+Alt+K.

4. Build your project Command+B.

2. @IBDesignable UIView在您的故事板中选择您的时，转到编辑器 -> 调试所选视图，并查看堆栈跟踪。

3. 删除派生数据文件夹。

   Xcode Preference -> Location -> Derived Data
   /Users/YourMacName/Library/Developer/Xcode/DerivedData
   

4. 清理你的项目Shift+ Command+ Alt+K。

5. 构建您的项目Command+B.

I solved the problem by doing the following:

我通过执行以下操作解决了这个问题：

1. Go to File > Workspace settings.
2. Click the little right arrow beside "Derived data". This opens the Finder app at the location of the DerivedDatafolder.
3. Go inside the DerivedDatafolder, and delete the folder corresponding to your project.
4. Quit Xcode, and re-open it.
5. Clean your project shiftcommandk.
6. build your project commandb.
7. Open your storyboard.
8. Go to Editor > Refresh all views.

1. 去File > Workspace settings。
2. 单击“派生数据”旁边的向右小箭头。这将在DerivedData文件夹位置打开 Finder 应用程序。
3. 进入DerivedData文件夹，并删除与您的项目对应的文件夹。
4. 退出 Xcode，然后重新打开它。
5. 清理你的项目shiftcommandk。
6. 构建您的项目commandb。
7. 打开你的故事板。
8. 去Editor > Refresh all views。

Sometimes just directly Go to Editor > Refresh all viewsworked. If Refresh all viewsis disabled, quit Xcode and try again.

有时只是直接去Editor > Refresh all views上班。如果Refresh all views已禁用，请退出 Xcode 并重试。

I just delete the view that is failed and press command+Z to undo deletion. It works for me.

我只是删除失败的视图，然后按 command+Z 撤消删除。这个对我有用。

If editing the failed view later, the error may occur again, do the above again.

如果稍后编辑失败的视图，可能会再次出现错误，请重新执行上述操作。

I faced this issue in CocoaPod 1.5.0. The solution is to reinstall pod again (pod install again) once this error showing or you may use CocoaPod 1.4.0 instead. It works fine in 1.4.0 (at least for me.)

我在 CocoaPod 1.5.0 中遇到过这个问题。解决方案是在出现此错误时再次重新安装 pod（再次安装 pod），或者您可以改用 CocoaPod 1.4.0。它在 1.4.0 中运行良好（至少对我而言。）

update:

更新：

Add following script in Podfile help me solve the issue in 1.5.0

在 Podfile 中添加以下脚本帮助我解决 1.5.0 中的问题

post_install do |installer|
  installer.pods_project.build_configurations.each do |config|
    config.build_settings.delete('CODE_SIGNING_ALLOWED')
    config.build_settings.delete('CODE_SIGNING_REQUIRED')
  end
end

Adding following code to my @IBDesignableclass did the trick.

将以下代码添加到我的@IBDesignable课程中就可以了。

override init(frame: CGRect) {
    super.init(frame: frame)
}

For anyone -like me- who can't find that IBDesignablesAgentCocoaTouchfile or when trying to 'Debug Selected Views' from the Editor gets an error, here's another way to debug those "Failed to render" errors.

对于无法找到该IBDesignablesAgentCocoaTouch文件或尝试从编辑器“调试选定视图”时出现错误的任何人（例如我），这里有另一种调试“无法呈现”错误的方法。

Open the 'Console' app, from the sidebar select your current Mac (it will probably be auto-selected by default) and then on the search bar search for "IBSceneUpdate" and hit enter.

打开“控制台”应用程序，从侧边栏中选择您当前的 Mac（默认情况下可能会自动选择），然后在搜索栏上搜索“IBSceneUpdate”并按 Enter。

This way, every time you get an Xcode error for an IBDesignablenot being able to render, you will also get a new "IBSceneUpdate" entry with more details about the error.

这样，每次IBDesignable由于无法渲染而收到 Xcode 错误时，您还将获得一个新的“IBSceneUpdate”条目，其中包含有关该错误的更多详细信息。

That's at least how I was able to debug my IBDesignableerrors!

这至少是我能够调试IBDesignable错误的方式！

Try to disable 'Use Trait Variations' (Identity and Type panel) for any xib file that you might have for custom views that are used in your storyboard.

尝试为故事板中使用的自定义视图可能拥有的任何 xib 文件禁用“使用特征变体”（身份和类型面板）。
