I am developing an app using the Ionic 4 framework and am currently attempting to build it for iOS and release it to the App Store. The error I am getting is when I attempt to run the app in Xcode, it will fail in the linking phase with the following error:
ld: 346 duplicate symbols for architecture x86_64 clang: error: linker
command failed with exit code 1 (use -v to see invocation).
This is preceded by a list of the duplicate symbols like so:
duplicate symbol _OBJC_IVAR_$_FIRInstanceIDURLQueryItem._name in:
/Users/james/Library/Developer/Xcode/DerivedData/Jambox-ataoinheliizvyaczvbklhkqvhpf/Build/Products/Debug-iphonesimulator/FirebaseInstanceID/libFirebaseInstanceID.a(FIRInstanceIDURLQueryItem.o)
Jambox/Plugins/cordova-plugin-firebase/FirebaseInstanceID.framework/FirebaseInstanceID(FIRInstanceIDURLQueryItem_ce817fff617a4255d51c2a25da32a1f0.o)
These are relating to the following frameworks:
FirebaseInstanceID.framework
GoogleUtilities.framework
nanopb.framework
FirebaseCore.framework
I have tried a few solutions to this problem, but none result in success:
1). Removing -ObjC and $(inherited) from Other Linker Flags - this causes the app to build and link successfully, but crash on startup with this error:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '+[FIRApp
registerAsConfigurable:]: unrecognized selector sent to class
0x1080bc178'
2). Removing each framework in the list of duplicate symbols - this helps in lowering the number of duplicate symbols. I can get it down to 65 duplicate symbols until I have to remove GoogleUtilities.framework, which causes the build the fail with this error:
Undefined symbols for architecture x86_64:
"_OBJC_CLASS_$_GULObjectSwizzler", referenced from:

command failed with exit code 1 (use -v to see invocation)
3). Deleting DerivedData folder - I get the same errors after doing this.
4). Removing and adding the iOS platform - Same errors.
In my case, this problem arose when using phonegap-plugin-push and cordova-plugin-firebase-analytics together. I found the fix in this issue thread.
Basically, go to your Project Navigator in Xcode, then 'Build Phases', expand 'Link Binary With Libraries', click '+' and Add 'libGoogleToolboxForMac.a' and 'libPodsYourProjectName.a' and redo the build.

I created a storyboard while I developing ios project in XCode. Then I delete it. When I delete it there asked Remove Reference or Move to Trash as following screenshot.
There I clikcked Remove Reference. After that I got Following Errors in my Objective C project.

After upgrade xcode to 10.1 the project's compile fails with :

The following work around worked for me:
in XCode select the project in the left panel
Click on "Build Settings"
In the "Linking" section, find"Dead Code Stripping" section and change it "No"
Clean and Build
*** In another project I got the same error but in that case the libraries were missing in "Settings of the failing Target"/"Build Phases"/"Link Binary With", so I had to add them manually!
Trying to figure out how to even start debugging this issue. I'm using Google VR on Unity, deploying to xcode for the build to iOS devices. I"ve opened the workspace instead of the project in xcode as referenced in:

I've attempted to fix as referenced in:

Still getting the same error and have no idea where to go from here.

Undefined symbols for architecture armv7:

objc-class-ref in addProductViewController.o
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)
The addProductViewController object is not found and it was referenced within AppDelegate. You do not link addProductViewController into your app. Check if your Compile Sources section within the Build Phases of your project shows addProductViewController.m
than˚s every body for your help
the problem was with arm 64 i just added it in my target and everything work fine
in architectures filed add standard architectures armv7,arm64
So I ran into this wierd issue where I am able to compile and run my iOS project in simulator with out any issues but when I ran it for profiling with instrument (cmd + I) I am getting Apple mach o linker error for one of the library. I tried it reading to project but it did not helped. I also checked my search paths which looks as following
Other Linker Flags: -ObjC -all_load
Always Search User Paths: No
Framework Search Paths:$(SRCROOT) recursive
Library Search Paths:$(SRCROOT) recursive
I am getting following error message:
Undefined symbols for architecture i386:
"_OBJC_CLASS_$_TestFlight", referenced from:
objc-class-ref in AppDelegate.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Am I missing anything in my linking phase which causing this thing to happen ?
It's not finding the TestFlight library. Easiest way to fix that is to find libTestFlight.a in the Xcode project browser and make sure your app is checked under "Target Membership" on the far right pane.
