Project Settings > Under "Targets", select your project > Build Phases > open "Compile Sources" and "Copy Bundle Resources". Check if any files are listed in red color. If so , just delete it. Then clean and run.
项目设置 > 在“目标”下，选择您的项目 > 构建阶段 > 打开“编译源”和“复制捆绑资源”。检查是否有任何文件以红色列出。如果是这样，只需将其删除。然后清理并运行。
Worked for me.

I had this same error and nobody seems to have an answer on StackOverflow that actually works. My problem was when I tried copying a project that was in a team repository. Turns out, in the ignore file, all files with the extension of *.pchwere ignored from repository commits. This means that when I went to pull the project from the repo, the .pchfile was missing, thus throwing this error.
我有同样的错误，似乎没有人在 StackOverflow 上有一个真正有效的答案。我的问题是当我尝试复制团队存储库中的项目时。结果是，在忽略文件中，所有扩展名为 的文件*.pch都从存储库提交中被忽略了。这意味着当我从 repo 中提取项目时，.pch文件丢失了，从而引发了这个错误。
Fortunately I had a copy of the project still and was able to just copy the .pchfile over and I was then able to compile just fine.
幸运的是，我仍然拥有该项目的副本，并且能够将.pch文件复制过来，然后我就可以很好地编译了。
Hope this helps?
希望这可以帮助？

Go to target preferences, summary tab, find "Deployment target" and increase it.
转到目标首选项，摘要选项卡，找到“部署目标”并增加它。

I face this problem too. And ofc I looked for help in SO instead of use the common sense and check the error message.
我也面临这个问题。而且我在 SO 中寻求帮助而不是使用常识并检查错误消息。
The last part of the error message was the same as you.
错误消息的最后一部分与您相同。

But few lines above I found:

Happy coding!

This problem usually occurs when there are more than two versions of XCode are installed in which different Swift versions incorporated for Ex. XCode 6.4 and XCode 7.3 are installed which are running Swift 1.2 and Swift 2.0. By mistake you tries to compile code with icorrect version for Ex. your project in in Swift 1.2 and you tries to compile it with xcode 7.3. In this case drive data stores information for swift version but when you tries to compile code with correct XCode it gives error. To resolve this
当安装了两个以上的 XCode 版本时，通常会出现此问题，其中为 Ex 合并了不同的 Swift 版本。安装了运行 Swift 1.2 和 Swift 2.0 的 XCode 6.4 和 XCode 7.3。您错误地尝试使用不正确的 Ex 版本编译代码。你的项目在 Swift 1.2 中，你试图用 xcode 7.3 编译它。在这种情况下，驱动器数据存储 swift 版本的信息，但是当您尝试使用正确的 XCode 编译代码时，它会出错。为了解决这个

Try this - click on the name of your project on the list of files/folders on the left in Xcode (at the very top of the list). Look at the "Targets" section on the left-hand side of the window to the right. Likely, there's two listed with the second being a "test" item. Right-click on that item and select "delete". Then try to run the project again.
试试这个 - 在 Xcode 左侧的文件/文件夹列表中点击你的项目名称（在列表的最顶部）。查看右侧窗口左侧的“目标”部分。可能列出了两个，第二个是“测试”项目。右键单击该项目并选择“删除”。然后尝试再次运行该项目。

For me this error appears after cloning the project from a repository. Someone removed a white space from the projects name (renamed: "The Project" to "TheProject") which caused some Build Settingserrors to unvalid paths.
对我来说，从存储库克隆项目后会出现此错误。有人从项目名称中删除了一个空格（重命名为：“The Project”到“TheProject”），这会导致Build Settings无效路径的一些错误。
Sometimes reading the whole error logs is not a bad idea....
有时阅读整个错误日志并不是一个坏主意......
