React-native-app-auth: iOS build failed, RNAppAuth, Unknown type name 'namespace' (Expo)

[mazikwyry]

I am trying to add react-native-app-auth to existing, but quite fresh project with Expo.
I'm following your setup guide, so doing following steps:

• yarn add [email protected] --dev
• Add pod 'AppAuth', '>= 0.91'
• cd iso && pod install
• react-native link

And I get:

rnpm-install info Linking react-native-app-auth ios dependency
rnpm-install WARN ERRGROUP Group 'Libraries' does not exist in your Xcode project. We have created it automatically for you.
rnpm-install info Platform 'ios' module react-native-app-auth has been successfully linked

which looks fine.

Then when I build in XCode i get the following error:

After searching the web I found it may be connected with compilator I changed it use Objective-C++:

and now I get more errors:

I also tried:

• Changing Target version to 9.0
• Doing it again
• Praying 🙏

Nothing helps :( Xcode Version 9.3 (9E145)

Hi @mazikwyry - Expo actually comes with AppAuth already built in. It might be easier for you to use their implementation if you've already got all the Expo code in your app anyway. The API is slightly different than ours, but here are some docs for it .

Disclaimer: I've never used the Expo version, I just know it exists.

[mazikwyry]

Hello @kadikraman. Thanks for suggestion. I didn't know about that. Does it mean that react-native-app-auth shouldn't be use with Expo? It's not compatible? Just trying to set up totally fresh app with this package to see if it's going to work.

EDIT: I have just setup a fresh Expo app following this guide and have exactly the same error. 😞

[kadikraman]

@mazikwyry - it should be fine to use with Expo, just wanted to let you know there's an alternative.

Could you try running your app using react-native run-ios instead of through Xcode and see if the build still fails? (this is to see if it's an issue with the Xcode compiler)

Does the Example app in this repo work for you? (this is to confirm the problem is definitely Expo)

[mazikwyry]

@kadikraman
react-native run-ios gives exactly the same errors as XCode build.
I've just removed Expo from my project altogether and setup react-native run-ios again following the same steps and now it works, so it looks like Expo was the problem.

Have the same issue at my project without Expo ("react-native": "0.55.4", "react-native-app-auth":"2.4.2").

Errors start to appear after adding to Podfile next code:

Need this code to fix issue with CodePush

Any suggestions?

Try linking the RN library through CocoaPods too, using the solution: https://sandstorm.de/de/blog/post/react-native-managing-native-dependencies-using-xcode-and-cocoapods.html

Unlink first
react-native unlink react-native-app-auth
Podfile configuration
pod 'RNAppAuth', :path => '../node_modules/react-native-app-auth/ios'
pod 'AppAuth', '>= 0.91'

I think this issue has something to do with boost-for-react-native. Using a fresh install of react native, I compared everything (build settings, linked libraries, code) between the fresh install (which worked with react-native-app-auth) and an Expokit project. The only clue I found was that Expokit appears to include boost in the pods, where the clean install didn't.

[Peter-Nagy]

I've experienced and managed to solve the same issue recently. The problem is that there is an import in header search paths, which searches in the whole /ios folder:
$(SRCROOT)/../../../ios/**
If you happen to use Expo and CocoaPods, there will be boost-for-react-native as a dependency inside your Pods folder. In fact, any package depending on boost will cause this problem. XCode tries to build boost as well, but it has some non-ObjC files, so it will fail.
The solution is not to include the whole /ios folder, but only these instead:

"$(SRCROOT)/../../../ios/YOUR_PROJECT_NAME",
"$(SRCROOT)/../../../ios/Pods/AppAuth/**",

To wrap things up, you can make it work by opening RNAppAuth.xcodeproj, switching to Build Settings tab and searching for header search paths, then replacing the above mentioned lines.

I'm still thinking about how this issue could be solved without hardcoding the project name. If I find a solution, I'm happy to make it into a pull request.

[Peter-Nagy]

I wanted to make this into a pull request but I've just discovered that it was fixed by this commit.

I think this issue can be closed now.

[kadikraman]

Thanks @Peter-Nagy - closing 🙅

@blyzniuk did you fix this issue? i am facing it.

@Peter-Nagy
Thanks. Removing Pods ... recursive from Header Search Paths fixed it for me
