Close Xcode and delete the folder <username>.xcuserdatadfrom within <projectname>.xcodeproj/xcuserdata/. Then restart Xcode, the schemes should re-appear.

关闭 Xcode 并<username>.xcuserdatad从<projectname>.xcodeproj/xcuserdata/. 然后重新启动 Xcode，方案应该会重新出现。

EDIT:You may need to delete from .xcodeprojfile and .xcworkspacefile

编辑：您可能需要从.xcodeproj文件和.xcworkspace文件中删除

I think this is happening when you are opening the app.xcworkspace not app.xcodeproj.

我认为当您打开 app.xcworkspace 而不是 app.xcodeproj 时会发生这种情况。

Solution: Install the pod and open the app.xcworkspace again.

解决方法：安装pod，再次打开app.xcworkspace。

The top answer fix didn't work for me when running the Xcode 8 beta's. but what did work was unplugging a connected device (iPhone, iPad etc.) and re plugging back in. The schemes would then reappear.

运行 Xcode 8 beta 时，最佳答案修复对我不起作用。但有效的是拔掉连接的设备（iPhone、iPad 等）并重新插入。然后这些方案会重新出现。

If you are using pods and using the correct workspace what I found to work best is simply open up terminal run pod update restart Xcode and every time it fixed the problem for me.

如果您正在使用 pod 并使用正确的工作区，我发现最有效的方法是打开终端运行 pod update 重新启动 Xcode，每次它为我解决问题时。

1. Close Xcode ["Force Quit Applications" (cmd+option+escape) to ensure]
2. Remove derived data of app (Xcode 9.4: Users/[username]/Library/Developer/Xcode/DerivedData/[app directory to delete])
3. Remove .xcworkspace from project directory
4. Also in project directory: .xcodeproj -> Right Click -> Show Package Contents -> remove .xcworkspace if exist -> xcuserdata -> remove [username].xcuserdatad

1. 关闭 Xcode [“强制退出应用程序”(cmd+option+escape) 以确保]
2. 删除应用程序的派生数据（Xcode 9.4：Users/[用户名]/Library/Developer/Xcode/DerivedData/[要删除的应用程序目录]）
3. 从项目目录中删除 .xcworkspace
4. 同样在项目目录中：.xcodeproj -> 右键单击​​ -> 显示包内容 -> 删除 .xcworkspace 如果存在 -> xcuserdata -> 删除 [用户名].xcuserdatad

It should do the trick. Install pods if needed and open project. Target should be available again.

它应该可以解决问题。如果需要，安装 pods 并打开项目。目标应该再次可用。

Firstly,when you are using Cocoapods to Develop iOS projects,you need to open the project with .xcodeworkspacefile instead of .xcodeprojfile.

首先，当你使用 Cocoapods 开发 iOS 项目时，你需要用.xcodeworkspace文件而不是.xcodeproj文件打开项目。

Secondly you can Show Package Contentswith .xcworkspacefile,you will find the contents.xcworkspacedatafile.

其次，您可以Show Package Contents使用.xcworkspace文件，您将找到该contents.xcworkspacedata文件。

<?xml version="1.0" encoding="UTF-8"?> <Workspace version = "1.0"> <FileRef location = "group:BluetoothColorLamp24G.xcodeproj"> </FileRef> <FileRef location = "group:Pods/Pods.xcodeproj"> </FileRef> </Workspace>

<?xml version="1.0" encoding="UTF-8"?> <Workspace version = "1.0"> <FileRef location = "group:BluetoothColorLamp24G.xcodeproj"> </FileRef> <FileRef location = "group:Pods/Pods.xcodeproj"> </FileRef> </Workspace>

pay attention to this line:

注意这一行：

location = "group:BluetoothColorLamp24G.xcodeproj"

location = "group:BluetoothColorLamp24G.xcodeproj"

The .xcworkspacefile has reference with the .xcodeprojfile.

该.xcworkspace文件具有与该.xcodeproj文件的参考。

If you find there is no file or wrong path about the location,you can link to your .xcodeprojfile,which works for me.

如果您发现该位置没有文件或路径错误，您可以链接到您的.xcodeproj文件，这对我有用。
