I am facing one problem : i am using Graph API in my application. app working fine every time but there are displayed 3 errors , though there are errors app is running...
1) error "_OBJC_CLASS_$_FbGraph", referenced from:
2) error "_OBJC_CLASS_$_FbGraphFile", referenced from:
3) Linker command failed with exit code 1 (use -v to see invocation)
for more information : I am using XCODE 4.3.2
what should i do to remove these errors ? need help...
i think define linkers flag with -all_load if required the -lstdc++, -ObjC, -lxml2....
and yes also check that Architecture define with these two armv6 and armv7.....
and then if its give error then define compiler with LLVM-GCC or LLVM and then restart app...
hope this help you..
:)

I recently upgraded my Xcode to the latest version and a big project I was working on had to be updated and fixed. Once the code updated I tried to run the app on simulator and iOS device but I always get the same error and I don't know where it comes from. I know it means the leveldb framework is missing but I don't find it anywhere on the internet. I am using Firebase.
Here's the error I get
ld: framework not found leveldb
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I would really appreciate if one of you knew how to fix this! Thanks
so today I updated my code to Swift 2 and now my app won't run because apparently the Parse Frameworks I was using have expired or something. This is the message I get: ld:
'/Users/tripphillips1/Desktop/Spotter/Parse.framework/Parse(PFAnalytics.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
Does anyone know what this means and how i can fix it?
Thanks
Ok so I found a solution to my problem. You have to go into the Build Settings and disable the Bitcode. Simple as that. Now it runs fine.
I'm working on a Swift app in Xcode 6. Everything was working okay until I decided to install cocoa pods and a pod. When I try to run it on the simulator, I get the following error:
ld: 91 duplicate symbols for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Before the error, there is a listing of all those duplicate symbols.
First few lines in error message:
Ld /<...>/Library/Developer/Xcode/DerivedData/<...>-gydnbbvfswpkkodlsuxdkpzkklzb/Build/Products/Debug-iphonesimulator/<...>.app/<...> normal x86_64
cd "/<...>/Documents/iOS Apps/<...>/<...>"
export IPHONEOS_DEPLOYMENT_TARGET=8.1
I even tried uninstalling the pod, but the error persists. I'm completely stuck – any help is much appreciated. Thanks!
Maybe you should update your CocoaPods to 0.36 or a later version, and add use_frameworks! to your Podfile. See this: CocoaPods 0.36 - Framework and Swift Support
Maybe :
You have put the same class implementation into two different files;
You actually have just one implementation of this class, however you are also linking in your project a framework or library containing a class whose name is exactly the same of yours.
When I want to start my app, I get this:
clang: error: invalid version number in '-mios-simulator-version-min= '
Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang failed with exit code 1
What's going on? When I google this error, I'm getting ZERO. This seems to be a very strange failure.
Please apologize, that I can't give more information. It's because I'm completely clueless.
Help!
OK, I've found the solution:
.xcodeproj > General > Deployment Target ----> was empty!
This is not allowed.
Try cleaning your project and/or quitting and relaunching Xcode. I've had various odd problems with Xcode that require one or the other of those things.
In my case there is a space after 8.0 like "8.0 ". When I remove space and re-build error disappears.
ive been trying to compile a mobile substrate tweak forever, but with no luck. so far, it compiles to the point where i get a .o file, but never to a .dylib. I keep getting the error:
ld: framework not found Foundation

right after it says linking
i know the foundation/foundation.h is in the include folder
ive googled forever but have found no answer
