Linking issues with manually (no Pods) iOS build

[lake-effect]

I followed the steps in https://github.com/mateusc42/react-native-firebase-mlkit#ios for an iOS manual installation, but when building either from the CLI or in XCode, I get the following error:

libRNFirebase.a is included in the build phases, and react-native itself builds and runs on its own. The error only comes up when I try to add this lib.

Is there a fix that doesn't require cocoapods?

[lake-effect]

One thing that took me further was adding a symlink in ios/Firebase/Analytics/FirebaseCore.framework/Headers/ inside a folder so we have ios/Firebase/Analytics/FirebaseCore.framework/Headers/FirebaseCore/FirebaseCore.h (alias).

At this point the build failure is:

/Users/user/project/node_modules/react-native-firebase-mlkit/ios/RNMlKit.m:7:9: fatal error: 'FirebaseMLVision/FirebaseMLVision.h' file not found
#import <FirebaseMLVision/FirebaseMLVision.h>
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

[lake-effect]

If you manually include the Firebase SDK in the project_root/ios/Firebase folder and create the above symlinks, adding the framework-included search path to RNMlKit's xcode project config is sufficient to resolve the first issue:

58B511F11A9E6C8500147676 /* Release */ = {
                        isa = XCBuildConfiguration;
                        buildSettings = {
                                HEADER_SEARCH_PATHS = (
                                        "$(inherited)",
                                        /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include,
                                        "$(SRCROOT)/../../../React/**",
                                        "$(SRCROOT)/../../react-native/React/**",
                                        "$(PROJECT_DIR)/../../../ios/Frameworks/**",
                                        "$(PROJECT_DIR)/../../../ios/Firebase/**",
                                        "$(PROJECT_DIR)/../../../ios/Firebase/Analytics/FirebaseCore.framework/Headers/**",
                                );

[lake-effect]

After following the above steps to get all the headers included, the symbol architectures don't line up at link time:

@lake-effect Any update of this issue?

[lake-effect]

I did eventually resolve all this. Let me see if I can summarize my changes and get back to this issue.

[lake-effect]

Okay, so, I performed the manual iOS configuration steps in the README, followed by these steps:

1. Ensure you have the associated Firebase libraries somewhere like src/ios/Firebase/ so they are reachable at build time
2. Add the associated headers from each required .framework file to the XCode project file in XCode
3. Optionally replace the RNCamera project file with projectWithoutFaceDetection.pbxproj as given in their docs
4. Modify the RNMLKit XCode project to include the relevant headers from your Firebase folder it needs
5. Copy the new RNMlkit.xcodeproj and RNMlKit.xcworkspace files with those resources imported into them someplace in your source control along with a script to copy them over the old ones at npm postinstall
6. Add execution of that script to npm postinstall. I have something like:

`"postinstall": "node ./scripts/android/android-release-gradle-fix.js; cd node_modules/react-native; exec ./scripts/ios-install-third-party.sh; cd third-party/glog-0.3.5; exec ../../scripts/ios-configure-glog.sh; cd ../../../..; exec mlkitconfig/init.sh; react-native link"`

You may recognize some of the calls there, and at this point you should be able to build.

The only open question at that point is adding the header paths to the RNMlkit project each time it's updated, which is a chore.

[1natsu172]

Hi, the same problem occurs with cocoapods in my environment. #import <FirebaseMLVision/FirebaseMLVision.h>

I think this is not a problem only for manual installation… 🤦‍♂️

[eyes2design]

#import <FirebaseMLVision/FirebaseMLVision.h>

/react-native-firebase-mlkit/ios/RNMlKit.m:7:9: 'FirebaseMLVision/FirebaseMLVision.h' file not found
I have in my Podfile this:
pod 'Firebase/Core'
pod 'Firebase/MLVision'
pod 'Firebase/MLVisionLabelModel'
pod 'Firebase/MLVisionTextModel'

I have checked that the framework exists in the build and that libRNMLKit.a is added to the link binary with libs and the RNMLKit xcodeproj is in the libs folder for the app.

I don't know what else to check it can't find the header file...

[fjsandov]

Same error #import <FirebaseMLVision/FirebaseMLVision.h> when I try to build it. I used react-native link so it isn't only a manual installation issue as @1natsu172 said. Does anyone know how to fix it?

[tienlx91]

@fjsandov add $(PROJECT_DIR)/../../../ios/Pods/FirebaseMLVision/Frameworks to System Framework Search Path on RNMLkit Project will solve the problem.

I have to re-add if every time I clean the project and remove node_modules folder

[fjsandov]

@tienlx91 thank you! it is building the project now, I hope it can be resolved without this manual fix every time you clean the project. Again, thank you @tienlx91. 😄

[oagostinho]

@tienlx91 I have the same problem but with your information, I could resolve the issue.

what can we do to resolve this situation automatically? Maybe could try to resolve this issue. What do you think?
