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.

I'm currently trying to integrate the Google Consent SDK, but as soon as I call
[PACConsentInformation.sharedInstance requestConsentInfoUpdateForPublisherIdentifiers:#[ #"pub-0123456789012345"]
I get the following error in Xcode console:

I've been searching Stackoverflow for a couple of hours now and I've tried various things such as Enabling Bitcode, Updating Linker Flags with $(inherited), as well as a few other things like adding suggested frameworks and libz found in popular questions/answers here, but still no luck.
I've gone as far to try my project in Xcode 8.3.2, Xcode 9.0 and Xcode 9.2, all of which show this error.
Is there anything I'm missing?
I'm completely stuck for ideas now.
Thanks for you help.
Go to Build Phase -> Link Binary With Libraries then add PersonalizedAdConsent framework
When trying to build my iOS app in Xcode, I get the following error message.

I have the latest version of Xcode. I have tried cleaning and deleting derived data but that did not help. I've noticed a lot of other people on the internet have similar error messages but the solutions did not help me.
Add the AVFoundation and CoreLocation frameworks to your target. After you do this, delete derived data, clean, and build again.
Also, check in your architectures under build settings and make sure that you have armv7 and armv7s listed under valid architectures. If the above answer does not fix your problem then try adding or removing arm64.
i'm using cocoapods for the first time and after everything goes well
i get to run my project that was always wor˚ and got those 2 errors in lin˚er
can anyone please tell me what is it
than˚s
Undefined symbols for architecture armv7:
"_OBJC_CLASS_$_PECropViewController", referenced from:
objc-class-ref in addProductViewController.o
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)
The addProductViewController object is not found and it was referenced within AppDelegate. You do not link addProductViewController into your app. Check if your Compile Sources section within the Build Phases of your project shows addProductViewController.m
than˚s every body for your help
the problem was with arm 64 i just added it in my target and everything work fine
in architectures filed add standard architectures armv7,arm64
Undefined symbols for architecture armv7:
"_OBJC_CLASS_$_Facebook", referenced from:
objc-class-ref in AppDelegate.o
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I've been snooping around here looking for an answer, but have yet to find one. I've tried what other people have suggested, as in using an older SDK copy but still get this linker error. The SDK tutorial Tutorial suggests after running the script they include to drag the folder into your project. When I drag the folder I get problems. When I create a directory in my project for the files and just drag the files, then it works, but still with this linker error.
Am I missing something else? I've followed the tutorial to the " T " and still can't figure it out.
Thanks
I need to incorporate QR in my app, im using zxing,
the scan test works wonderfully, and when importing the widget after following all instructions, all goes fine,
but
I have this errors when implementing the code for the widget and QRCodeReader
Undefined symbols for architecture i386:
"_OBJC_CLASS_$_ZXingWidgetController", referenced from:
objc-class-ref in AttendanceVC.o
"_OBJC_CLASS_$_QRCodeReader", referenced from:
objc-class-ref in AttendanceVC.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
so how to fix this please?
edit:
my Architectures on build settings is: i386 armv6 armv7
thanks a lot!
Double check step 2 in the README. Under Link Binary with Libraries you must have libZXingWidget.a and it sounds like you don't.
Check the Valid Architectures in the build settings. Check out these links.
Undefined symbols for architecture i386: _OBJC_CLASS_$_SKPSMTPMessage", referenced from: error
Undefined symbols for architecture i386
EDIT : Usually these type of linker errors occur due to the link issue in your compiler or link issue with your added frameworks or your libraries. check whether you are using a suitable compiler, check whether you have added all the required libraries and frameworks. Also check whether you have imported all the libraries and frameworks properly. Please check all these things too once. For guidance on this check the below links

I had the same issue and following configuration in "Build Settings" works for me.
