I'm working on a book project and the project is connected by API . I'm working on the book app which has different libraries imported from the various places.
Recently, i cloned the project from bitbucket in Xcode and tried to run it. The result i got i error as follows:
enter image description here
It shows :
ld: in /Users/ishinfoservices/Documents/vadltaldhambooks/Pods/FirebaseAnalytics/Frameworks/FIRAnalyticsConnector.framework/FIRAnalyticsConnector(FIRAnalyticsConnector_a8eeba373b74508311b8b22b8d3202a6.o), building for iOS Simulator, but linking in object file built for iOS, file '/Users/ishinfoservices/Documents/vadltaldhambooks/Pods/FirebaseAnalytics/Frameworks/FIRAnalyticsConnector.framework/FIRAnalyticsConnector' for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Help needed to fix the error, as the project has lots of mixes of old libraries along with .h and .m files, the swift files with wireframes
According to the image I saw that you are trying run the app on the iOS simulator, then you could try to add the arm64 to the Excluded Architectures on the Build Settings section of your project or target, it would be like:
Take in mind that if you use Cocoa Pods is possible that also you should add the arm64 to the Exclude Architectures into the Pods project
After the above, clean, build and run the project on the iOS simulator, is possible that on your physical device you must remove the arm64 from the Exclude Architectures, it could depend on what you use in your project.
On the other hand, you can try the following: Select the project -> Select the target -> Go to the Build Phases -> Expand the Link Binary with libraries and add all pod libraries (remove if they exist in embedded binaries or Remove the old FrameWorks), after that, clean and build the project
I'm using Firebase via RNFirebase in React Native. I've gone through the steps here: https://rnfirebase.io/docs/v5.x.x/installation/ios.
Debug builds in the Simulator and to my device work just fine, but when I attempt to archive a Release build it fails with this error.

Also in the build logs I can see that the Debug config builds those targets, but they are not in the output for Release config builds. I get the feeling it has to do with building for all architectures, but don't know how where to start solving that. I just feel like I am poking around without a real strategy to solve it. Any ideas?
Some things I have tried...
Using the Legacy Build System
Removing node_modules and rerunning npm install
Removing / adding the related pods
Deintegerating and readding Cocoapods
Clearing DerivedData
Restarting my computer
I've seen this happen when switching use_frameworks! off and on.
The solution was deleting FirebaseAuth and other libraries from the Build Setting - Other Linker Flags(OTHER_LDFLAGS)
I got help from this PR: https://github.com/invertase/react-native-firebase-starter/pull/61
It was a combo of dropping down to the Legacy Build System in Xcode 10 and upgrading React Native to 0.57.2.
I have forked a framework called BTNavigationDropdownMenu (swift project for ios). all worked fine till I tried to add a dependency to the latest version in the branch I created. the problem is the same whether I add the other framework (DYBadge) through a podfile or through Carthage.
Auto-Linking framework not found DYBadge.
It seems to have a problem with a UIView extension that is part of DYBadge.
DYBadge works fine in my main app I'm working on (I also need it in the app target).
errors below. thanks for any hints into the right direction.

Xcode is not able to find your frameworks because the FRAMEWORK_SEARCH_PATHS is probably not set or is wrong (happened to me because I moved the Info.plist file).
You can fix this by going into your target and adapt the Build Settings. Simply search in there for FRAMEWORK_SEARCH_PATHS and add the correct one, which is usually $(PROJECT_DIR)/Carthage/Build/iOS (for iOS projects). $(inherited) should also be in there as the first entry.
This is the post of #user3122959 answer in the comments, which helped me and others to fix this problem and was requested to put in as the answer to this question.
Try this process -
Press "Cmd + Shift + K" or shift + cmd + alt + k to clean up, and quit Xcode.
Delete the cache Run "rm -rf ~/Library/Developer/Xcode/DerivedData" in terminal
Open the project and re-build it
I had this problem accessing 3rd party frameworks from my tests. Here's how I fixed it.
In Xcode goto: Your Unit-Test target > Build Phases > Link Binary With Libraries
In Finder goto: Carthage > Build > yourframework.Framework
Drag the framework in to your build phases then clean (cmd - shift - K).
This can also be an error if you use a framework that has Bitcode Enabled on false.
Bitcode Enabled can only be true if all frameworks also have Bitcode enabled true.
Go to your targets build settings and disable bitcode.
For me this fixed it:
Go to Project > Targets > Build Settings (Tab) > Build Options (Heading)
Set Enable Testing Search Paths to Yes.
Instantly back up and running. Honestly not sure what this means but it worked.
If you are using Carthage and several Projects within one Workspace you have to add a symlink to your Main Carthage Folder. it will depend what structure you have, but for example if you have
Project -> Carthage
Project -> Frameworks -> MyImbaFramework than cd in terminal in MyImbaFramework folder and run
ln -s ../../Carthage Carthage
In my case, there was an issue with Bitcode, but Xcode couldn't give an accurate error diagnostic since the project framework references were also somehow messed up. Running the framework tests worked fine, but archiving gave the auto-linking error.
Deleted all framework references from the project, including the Frameworks group they were under, added them back again resolved the references issue, then I got the bitcode issue, which I disabled on the target framework, then and only then, archiving was successful
I had a similar error and none of the suggestions on this page worked. It occurred when trying to create an archive when pointing to my test iPhone, when I changed it to 'Any iOS Device' it worked correctly. I suspect this is related to the recent change to add support for Apple Silicon but I'm not certain how.
Make sure you haven't set a testfile that imports XCTest's TargetMembership to the main target, but to a test target :-)
Hope this helps someone, this is what worked for me
rm -rf ~/Library/Developer/Xcode/DerivedData
rm -rf Pods
rm Podfile.lock
pod cache clean --all
pod install --repo-update
and cleaning the build folder
XCode > Product > Clean Build Folder
or
⌘ Command + ⇧ Shift + K
then closing XCode an clearing the derived data again
rm -rf ~/Library/Developer/Xcode/DerivedData
For me, the problem was that I had set the "Other Linker Flags" setting prior to converting my project to use Cocoapods. To fix this, I changed that field to use $(inhereted) and everything worked after that.
I am getting a Apple Mach-O Linker Error everytime I import a file from CocoaPods.
Undefined symbols for architecture arm64:
"_OBJC_CLASS_$_FBSession", referenced from: someFile
ld: symbol(s) not found for architecture arm64
I get about 12 of these, for the various Pods I use.
I am trying to build for the iPhone 5S using XCode 5.
I've been trying various solutions here on SO, but haven't got any of them to work yet.
How do I fix this Apple Mach-O Linker Error?
Just found another warning that might be interesting, I hope this leads me to the solution:
Ignoring file ~/Library/Developer/Xcode/DerivedData/SomeApp/Build/Products/Debug-iphoneos/libPods.a,
file was built for archive which is not the architecture being linked (arm64):~/Library/Developer/Xcode/DerivedData/someApp/Build/Products/Debug-iphoneos/libPods.a
If your Architectures and Valid Architectures are all right, you may check whether you have added $(inherited) , which will add linker flags generated in pods, to Other Linker Flags as below:
The issue is that the cocoapods have not been built for arm64 architecture yet thus they cannot be linked when you build them. Likely you cannot use those packages until they are updated and use that architecture. You can fix the linker error by going to project -> target (your project name) -> build settings and change architectures to standard architectures (armv7, armv7s), and valid architectures to armv7, armv7s.
Note though, this means you won't get the full power of the 64 bit processor. You said you are building for the 5s, so there may be some reason you need this. If you for some reason absolutely need that power (perhaps you are building a game), and desperately need those files, you could submit a pull request and then recompile the project to arm64 by setting those same fields to arm64 in the files you pulled from the open source projects. But, unless you really need these files to be 64 bit compatible, that seems like a bit of overkill for now.
EDIT: Some people also reported that setting Build For Active Architectures to YES was also necessary to solve this problem.
As of 2014-04-28 the setting should look something like this:
I solved this problem by setting that:
ARCHS = armv7 armv7s
VALID_ARCHS = armv6 armv7 armv7s arm64
I ran into the same/similar issue implementing AVPictureInPictureController and the issue was that I wasn't linking the AVKit framework in my project.
The error message was:
Undefined symbols for architecture armv7:
"_OBJC_CLASS_$_AVPictureInPictureController", referenced from:
objc-class-ref in yourTarget.a(yourObject.o)
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)
The Solution:
Go to your Project
Select your Target
Then, go to Build Phases
Open Link Binary With Libraries
Finally, just add + the AVKit framework / any other framework.
Hopefully this helps someone else running into a similar issue I had.
I also encountered the same problem , the above methods will not work . I accidentally deleted the files in the following directory on it .
Folder emplacement:
~/Library/Developer/Xcode/DerivedData/
Set Architectures to armv7 armv7s, Build Active Architecture Only to NO, for every target in the project, including every one in Pods
I fixed mine by checking the selected implementation files in the target membership on the right side. This is useful especially in dealing with extensions i.e. custom keyboards.
Here are some explanations why build_active_architecture is set to NO.
Xcode now detects which devices you have connected and will set the active architecture accordingly. So if you plug a 2nd generation iPod Touch into your computer, Xcode should set the active architecture to armv6. Building your target with the above Debug configuration will now only build the armv6 binary to save time (unless you have a huge project you may not notice the difference but I guess the seconds add up over time).
When you create a Distribution configuration for publishing to the App Store, you should make sure this option is not set, so that Xcode will instead build the fat universal binary
http://useyourloaf.com/blog/2010/04/21/xcode-build-active-architecture-only.html
This might be related to libz.dylib or libz.tbd, just have to add it to your targets for the linking binaries, and try to compile again.
You need to just remove arm64 from Valid Architecture and set NO to Active Architecture Only . Now just Clean, Build and Run. You will not see this error again.

Solved after deleting the content of the DerivedData-->Build-->Products-->Debug-iphoneos
I solved it by setting valid archs to armv7 armv7s and setting build active architectures only to YES in release and then doing a new "pod install" from the command line
Following worked for me:
Remove all pods
cd ios && pod deintegrate
Comment this line in ios/Podfile -> use_flipper!()
Reinstall all pods arch -x86_64 pod install
Run your app :) npm run ios
Environment:
Node version: 14.17.1
RN version: 6.0.0
OS: macOS BigSur m1
Given an iPhone 5s and not yet having received a 64 bit version of a third party library, I had to go back to 32 bit mode with the latest Xcode (prior to 5.1 it didn't complain).
I fixed this by deleting arm64 from the Valid Architectures list and then setting Build Active Architecture Only to NO. It seems to me this makes more sense than the other way around as shown above. I'm posting in case other people couldn't get any of the above solutions to work for them.
I had the same problem after upgrading to Xcode 5.1 and fixed it by setting Architectures to armv7 armv7s
Had been stuck on this issue the whole day.
I had multiple Schemes, it was compiling fine for Demo, Internal, Release - however Debug scheme just would not compile and was complaining about the libPods.a missing.
The solution was to go to the Project -> Target -> Build Settings and change "Build Active Architecture Only" to YES. Clean and build! Finally hours of head itching solved!
Setting -ObjC to Other Linker Flags in Build Settings of the target solved the problem.
This worked for me:
ios sdk 9.3
into your build setting of app.xcodeproj
valid architecture: armv7 armv7s
Build Active architecture : No
Clean and build , worked for me.
If you faced this issue on your Flutter project while building in Release mode (or Archive) check out my this answer: https://stackoverflow.com/a/61446892/5502121
Long story short:
set your build system to New Build System in File > Project Settings…
remove ios and build_ios folders
run flutter create . to init new ios module
run pod install
run flutter pub get
check your Xcode build config (it should be Release mode and General iOS Device)
and you're good to go
The following worked for me to get GPUImage compiling without errors on Xcode 5.1 for both the 64-bit simulator and retina iPad Mini, without needing to remove arm64 from the Valid Architectures list (which defeats the purpose of owning a 64-bit device for testing 64-bit performance).
Download the .zip folder from the GitHub page: https://github.com/BradLarson/GPUImage
Unzip, and navigate to the 'framework' folder. From here, add and copy the 'Source' folder into your Xcode project. Ensure 'Copy items into destination group's folder' is ticked, and that 'Create groups for any added folders' is also ticked. This will copy the generic, iOS and Mac header/implementation files into your project.
If you don't need the Mac files because you're compiling for iOS you can delete the Mac folder either before you copy the files into your project, or simply delete the group from within Xcode.
Once you've added the Source folder to your project just use the following to begin using GPUImage's classes/methods:
#import "Source/GPUImage.h"
A few things to point out:
If you get an error saying 'Cocoa' not found, you've added the Mac folder/headers into your iOS project - simply delete the Mac group/files from your project and the warning will vanish
If you rename the Source folder (not the group in Xcode), use that name instead of "Source/GPUImage.h" in the #import instruction. So if you rename the folder to GPUImageFiles before you add to your project, use: #import "GPUImageFiles/GPUImage.h
Obviously ensure arm64 is selected in the Valid Architectures list to take advantage of the A7 64-bit processor!
This isn't a GPUImage.framework bundle (such as if you downloaded the framework from http://www.raywenderlich.com/60968/ios-7-blur-effects-gpuimage) so it may not the correct way to use GPUImage that Brad Larson intended, but it works for my current SpriteKit project.
There's no need to link to frameworks/libraries etc - just import the header and implementation source folder as described above
Hope the above helps - it seems there were no clear instructions anywhere despite the question being asked multiple times, but fear not, GPUImage definitely works for arm64 architecture!
This issue occurred for me after installing a pod via Podfile and pod install. After trying a bunch of different fixes I finally just imported the Pod manually (dragging the necessary files into my project) and that solved the problem.
As morisunshine answer pointed in right direction, a little tweak in his answer solved my problem for iOS8.2 .Thanks to him.
I solved this problem by setting that:
ARCHS = armv7
VALID_ARCHS = armv6 armv7 armv7s arm64
BUILD ACTIVE ARCHITECTURE ONLY= NO
Go to target Build Settings.
set BUILD ACTIVE ARCHITECTURE ONLY = NO for both Debug and Release
Build and run
In my case, I had to look for
C++ Standard Library and make sure that the libc++ was the one selected.
For me, I use opencv 2.4.9 in xcode 7.2 for iOS and the errors above occurred, and I solve the errors by using the opencv through pod install rather than offline opencv framework.
You can have a try by adding the opencv pod text below and delete the offline opencv framework if you have used.
pod 'OpenCV', '2.4.9'
None of the solutions fix this error in my case(Xcode 9), with TesseractOCRiOS. After hours of trial and error, I came up with a good solution. I just delete 'pod 'TesseractOCRiOS', '~> 4.0.0' in the Podfile, run pod install. And then, add pod 'TesseractOCRiOS', '~> 4.0.0' back to Podfile and run pod install again.
Bang! It works!
"The OPN [Debug] target overrides the OTHER_LDFLAGS build setting". This was the main issue. After adding $(inherited) in new line in other linker flags solved my issue.
in some case, if you define one more interface in a .h file, but did not implementation all these interface, this error occurred.
The linker can't found the implementation in .m file, so you need to implementation it in your .m file for every interface.
To resolve this error:
1.in .m file, supply the implementation for each interface.
2.rebuild
I faced the same issue.
My solution I found here: Why linker link static libraries with errors? iOS
Adding $(TOOLCHAIN_DIR)/usr/lib/swift/$(PLATFORM_NAME) to the library search paths fixed the problem.
This error consumed my whole day so thought of writing what really worked for me
delete .xworkspace
delete podfile.lock
delete the Pods folder/directory
"DO NOT DELETE PODFILE"
After all this, CLEAN(OPTION + SHIFT + CMD + K) --> BUILD(CMD + B) --> RUN(CMD + R)
I hope this really works for you :)
