Linker command failed with exit code 1 when using Google Analytics via CocoaPods

Question

I m trying to add Google Analytics to an iOS app written in Swift  I ve followed the guide that adds the frameworks via CocoaPods and added a bridging header but I m still getting   Linker command failed with exit code 1   My podfile does have use frameworks  so I m wondering if that has anything to do with it    there is no additional information on the Analytics site from what I can see   EDIT  I ve noticed that after viewing the full error message the following is displayed   ld    Users simon Programming VenueNow Pods GoogleUtilities Libraries libGTM NSData zlib a GTMNSData zlib o   does not contain bitcode   You must rebuild it with bitcode enabled  Xcode setting ENABLE BITCODE   obtain an updated library from the vendor  or disable bitcode for this target  for architecture arm64   And searching for that issue brings up that Google updated to support bit code but hadn t updated the cocoa pods framework at that time

You have another option    install Google Analytics without using CocoaPods       https   developers google com analytics devguides collection ios v3 sdk-download

This worked for me      you have to remove libPods a library from Linked Frameworks and   Libraries section of target

I had this same issue  Fortunately you can use Google Analytics with BitCode enabled  but it s a bit confusing due to how Google had set up their CocoaPods support   There s actually 2 CocoaPods you can use     Google Analytics   GoogleAnalytics    The first one is the  latest  but it s tied to the greater Google pods so it does not support Bitcode  The second one is for Analytics only and does support BitCode  However because the latter does not include extra Google pods some of the instructions on how to set it up are incorrect   You have to use the v2 method of setting up analytics      Inside AppDelegate      Optional  automatically send uncaught exceptions to Google Analytics  GAI sharedInstance   trackUncaughtExceptions   true     Optional  set Google Analytics dispatch interval to e g  20 seconds  GAI sharedInstance   dispatchInterval   20     Create tracker instance  let tracker   GAI sharedInstance   trackerWithTrackingId  XX-XXXXXXXX-Y     The rest of the Google analytics api you can use the v3 documentation  you don t need to use v2    The  Google Analytics  cocoapod as of this writing still does not support BitCode  See here

Go to your build settings and switch the target s settings to ENABLE BITCODE   YES for now

User · Answer

I resorted to adding Analytics via cocoa pods again and disabled bit code for now   Hopefully a future cocoa pods version will support it

Had this issue  but it wasn t related to the bitcode setting  I had somehow ended up with duplicate framework files in the Frameworks folder of my XCode project  I deleted all frameworks files that were red  and duplicates   This solved the  Apple Mach O  Linker Command failed with exit code 1  error

Close Xcode  rename the folder  Then make a new folder with the previous name  Run the project  stop the project  Delete the new folder  rename old folder and re-run    My iPad Pro simulator is affected with this issue  Its something that makes me upset  so much hard work    hopefully Google works through bugs for the next SDK

Try to remove any trace of cocoapods pods using pod deintegrate then Run pod install

User · Answer

This usually happens when using Cocoapods and you are building from the xcproject which doesn t know about the cocoapod libraries

User · Answer

Some times appeared if you declare a constant in the header file without static notation   like this  const int k   10    it should be    static const int k   10

User · Answer

Make sure you open the  xcworkspace file not the project file from xCode Project menu when working with pods  That should solve the issue with linking
