I'm experimenting an issue since some days ago, and I don't know what I made to have my project under a bad configuration. I hope explain it in a good way:
If I configure my scheme with build configuration set to Release, the build is ok. But when I changed the build configuration to Debug, the build is failed with the following error:
Undefined symbols for architecture x86_64:
"_OBJC_CLASS_$_RCTReconnectingWebSocket", referenced from:
objc-class-ref in libReact.a(RCTPackagerConnection.o)
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
My project is a react native ejected with ExpoKit:
"expo": "^19.0.0",
"react-native": "https://github.com/expo/react-native/archive/sdk-19.0.0.tar.gz",
Plus, the project has CocoaPods as a dependency manager (so I open the project with the xcworkspace file).
Any ideas what do I have wrong?

Building with Unity 2018.4.2 - Xcode 10.2 - Latest iOS Targets
Firebase Latest (6.1.1) for Unity with .Net 4
For Firebase We are using the following unity packages:
- FirebaseMessaging.unitypackage
- FirebaseAnalytics.unitypackage
Get the following Build Error in Xcode:

On another Machine same error however armv7 target:

Tested Solutions (no solution yet):
Obj-C to frameworks (was already there)
Updated Cocoa Pods to Latest
Deleted Developer/Xcode/DerivedData
Updated Cocoa Pods and deleted caches
The strangest thing is this only started happening on Monday, previously was working, nothing else was changed, so this leads to believe this is Google changed something in their Cocoa pods library which is linking agains't another package which is not included now.
Problem does not occur in the same Android Variant of the Project.
Solution:
It now requires you to also include and install Firebase: DynamicLinks in order to compile for iOS.
FirebaseDynamicLinks.unitypackage
So install the following package into your unity project from the download of Firebase Unity.
I am integrating AppRTC to my hybrid app (ionic 3 and angular 4)...
iOS AppRTC Integration: https://github.com/ISBX/apprtc-ios
I've successfully installed the pod and build the project without errors but when I add
[RTCPeerConnectionFactory initializeSSL];
to my
application:didFinishLaunchingWithOptions:
When I build the project I get the following errors:
Undefined symbols for architecture arm64:
"_OBJC_CLASS_$_RTCPeerConnectionFactory", referenced from:
objc-class-ref in AppDelegate.o
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see
invocation)
Already searched the net but couldn't find a solution...
Added " ${inherited} $(OTHER_LDFLAGS) -ObjC -all_load" to the linker library, restart and clean xcode, deleted the DerivedData file but the issue still persist.
Not sure if this will help as you have installed from a pod but we got the same error when the framework search path was wrong. $(inherited) pathToWebrtcFramework. With this option we had built the webrtc framework ourselves using the instructions at https://webrtc.org/native-code/ios/.
Also set build active architecture only to yes.
I am using tesseract provided by google. After following this tutorial, i finally built finish my app. However, when i run it, i run into the problem of undefined symbols. This is the error
Undefined symbols for architecture x86_64:
"_OBJC_CLASS_$_G8Tesseract", referenced from:
objc-class-ref in ViewController.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
How do i fix this issue? I tried searching online but none of the solutions worked for me. I tried reinstalling the pods and updating it. Then i faced this error
clang: error: no such file or directory: '/Users/admin/Desktop/tst/Pods/Target Support Files/Pods-tst/Pods-tst-dummy.m'
clang: error: no input files
When i tried redoing the project i get his error
Undefined symbols for architecture arm64:
"_OBJC_CLASS_$_G8Tesseract", referenced from:
objc-class-ref in ViewController.o
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Apparently i had to add the TesseractOCR.framework separately even after using cocoa pods and disable Bitcode. This prevented the errors.
I think you should update pod version:
sudo gem install cocoapods
After this run:
pod update --verbose
Since Tesseract requires libstdc++.6.0.9.dylib (or libstdc++.6.0.9.tbd if libstdc++.6.0.9.dylib is unavailable in your current Xcode version) and CoreImage.framework you’ll need to link both of these libraries in.
In the General tab, scroll down to Linked Frameworks and Libraries.
There should be only one file here: TesseractOCR.framework, which you just added. Click the + button underneath the list. Find both libstdc++.dylib (or libstdc++.6.0.9.tbd) and CoreImage.framework and add them to your project.
Im having hard time to build the project after adding GoogleAppIndexing (deep linking) pod to my project. Google's Install Instructions
Im a newbie in IOS , in fact i know very little about objC, My app is written in react native.
Im getting these exception on build.
Undefined symbols for architecture x86_64:
"_OBJC_CLASS_$_GSDAppIndexing", referenced from:
objc-class-ref in AppDelegate.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
as i understand the message pod/lib is not compatible with 64bit environments , doesn't make any sense .
im using xcode 6.4 .
Thanks
GoogleAppIndexing Lib is IOS 9 and above.
I seem to be getting the error message while trying to compile TestFlightSDK in my app via cocoapods
Im my Podfile i have the line:
pod 'TestFlightSDK'
And the pod update works fine.
When i try and compile the app i get the message:
Undefined symbols for architecture i386:
"_OBJC_CLASS_$_TestFlight", referenced from:
objc-class-ref in OurDealAppDelegate_iPhone.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
my app is only supporting Architecture armv7 (because if i add armv7s or arm64 older libraries fail to compile - so i assume its something to do with this.
Is there any work around for this?
Okay, you need to confirm whether Cocoapods has included libTestFlight.a library in your project. Cocoapods has never added the library for me.
So, please follow the steps below:
Open the Pods-TestFlightSDK target in the Pods.xcodeproj project
Open Build Phases tab and add libTestFlight.a
libTestFlight.a can be found at [$SRCROOT]/Pods/TestFlightsSDK
