None of the previous answer have solve my problem.
I think it come from changes in the cocoapods podFile, from using frameworks to not using them 

Frameworks was still remind in Target>General Properties>Linked Frameworks. I removed them
I also remove the -framework and corresponding frameworks from other linker flags (saving inherited and objC flags)

This is because at some point some project file was not compiled. In my case the AppDelegate.swift was not in the compiler. So I added it manually and it worked.

I had the same problem when I changed Xcode from a previous version 7 to the new XCode 8. In the new Xcode (8.3.3 now) there are more settings in the compiler. 

When you update the project settings into new Xcode (using Editor->Validate Settings), these new settings are applied and set to the default value YES. After this update I had the linker error!

In my project I compared the previous version of the file .pbxproj with the new one (after Settings validation) using Beyond compare (or similar).

In this way I can saw the new settings added in the new version of Xcode and I set the new Settings value to NO. After this update all was OK and the linker error disappear.

blocks|key|2624184|text|在清理派生数据和项目以及重新启动xcode的基础上，我发现正在将项目转换为当前的快速语法，如果您有它们，则重新安装pods也会有所帮助。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2624185|要重新转换您的项目，您需要将swift_version构建设置为“是”，以便您的目标出现在转换列表中。|2624186|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

On top of cleaning derived data and the project and restarting xcode, I've found that re converting your project to current swift syntax and re installing pods if you have them also helps.

To re convert your project you will need to set swift_version build setting back to yes so that your target appears in the conversion list.

The issue I found with XCode 8.2.1 (Version 8C1002) after I converted the project to Current Swift Syntax (Swift 3). I just needed to rebuild it after cleaning, and the errors disappeared.

blocks|key|2624469|text|如果清除和禁用bitcode的过程不起作用，那么错误的原因可能只是代码中一个更复杂的语法错误。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2624470|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

If the procedure of cleaning and the disabling of bitcode does not work, then it's possible that the reason for the errors simply is a more complex syntax error in your code.

I got the same problem because I had defined a class (using @interface), but did not provide an implementation (using @implementation) for it. It was a simple class so even an empty implementation resolved it.

blocks|key|2624603|text|另外，只需检查是否要在任何类中导入"*.m“实现文件，这会导致同样的问题。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2624604|删除导入语句可以修复此问题。|2624605|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

Also just check if you are importing a "*.m" implementation file in any of your classes, that can cause the same issue. 

Removing the import statement can fix the issue

blocks|key|2624655|text|对我来说，这是一个反应本土触觉的问题。我认为这是因为CocoaPods发生了变化，但也是因为文件位置的改变。我刚把它取下来重新安装了。希望这能帮上忙。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2624656|更新|offset|length|style|BOLD|2624657|当运行它时，这个构建成功了，它只会崩溃。为了解决这个问题，我使用了File+>AddFilestoProjectforGoogleServiceInfo.plist，它成功了。|2624658|entityMap^0|0|0|2|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|M|8|@$D|N|E|O|F|G]]|9|@]|A|$]]|$1|H|3|I|5|6|7|P|8|@]|9|@]|A|$]]|$1|J|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|K|$]]

For me it was a problem with react native haptic. I think it was because of a change in CocoaPods but also because of changing up file locations. I just removed it and re installed it. Hope this helps someone.

UPDATE

The build succeeded by when running it it would just crash. To solve this I used File > Add Files to Project for the GoogleService-Info.plist and it worked.
