I have followed this tutorial LINK
but i get a linker error when i added the lib and its .h to the project.
i searched google and i found that -ObjC and -all_load should be addd in setting i did it but the error couldn't be solved.The error is as follows:
ld: warning: ignoring file /Users/techvedika/Desktop/RND/MathTest/MathTest/iCodeBlogsMathLibrary/libICodeMathUtils.a, missing required architecture i386 in file /Users/techvedika/Desktop/RND/MathTest/MathTest/iCodeBlogsMathLibrary/libICodeMathUtils.a (3 slices)
Undefined symbols for architecture i386:
"_OBJC_CLASS_$_MathFunctions", 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)
how do i solve this?
Can you please check lipo -info libICodeMathUtils.a on terminal. If it is not listing architecture i386 that means your library is not build for simulator. And it will not work on simulator
obviously, this is not a crash , it's just a link error, your project lack of i386 version libICodeMathUtils.a, so you should first add libICodeMathUtils.a to your project.
The MathFunctions class is missing. Either from your application project or from the SimpleLibrary.a that you use. Make sure it is part of the compilation and linking steps of your build.

I added a SDK manually into my swift project that was wrote in obj-c and I create bridging header for the header file of it.
I can use all functions and classes defined in SDK and Xcode knows them (by changing their color and no errors) but when I run the project there is one error and one warning:

If MESDK is your framework you need to add the missing architecture in the build settings of MESDK project (supported architectures) to support it
If it's not yours, you need to ask from the developer to do it...

FRAMEWORKS
I am using XCode 6.2
Thanks
edit:
I've added the frameworks social, and accounts. Same error still occurs.
I ended up fixing this issue by deleting the Parse and Bolts framework, and re adding it back into the project.
Edit:
The best solution to this issue is by using cocoapods. It handles the dependencies better than manually dragging in the framework files.
I had this question going on, but now I am a little further:
I added this framework to my project:
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/Frameworks/AdSupport.framework
Now this works fine if I run the app on any device, however this framework is just for the architectures armv7, armv7s and arm64
When running the app on the simulator, the build fails because the architecture i386 is missing. This is included in:
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/System/Library/Frameworks/AdSupport.framework
How can I achieve that all architectures can be used? I played a lot with the build-settings but nothing worked so far!
error report:

Thanks a lot!
Go to the Project Target.and make architecture like below image.
/Users/XXXXXXX/Documents/app1/app1/AdSupport.framework/AdSupport is missing an i386 slice; I suspect that it was likely built for arm and not intel. It looks like that framework is external to your project, so I suggest you rebuild it for the simulator.
You can check the current architectures of the framework by running file /Users/XXXXXXX/Documents/app1/app1/AdSupport.framework/AdSupport
I have a project that uses CocoaPods. It was working but something got broken.
It does compile if I target the simulator, but If I target the devise (Build or Archive) it throws a linker error.
ld: warning: ignoring file /Users/myuser/ios/share/share/libPods.a, file was built for archive which is not the architecture being linked (armv7s): /Users/myuser/ios/share/share/libPods.a
Undefined symbols for architecture armv7s:
"_OBJC_CLASS_$_AFHTTPRequestOperationManager", referenced from:
objc-class-ref in BackendProxy.o
ld: symbol(s) not found for architecture armv7s
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I really need some help because I am really stucked.
Thanks!
EDIT: i deleted that libPods.a, that was an old one, and now it's giving me:
ld: library not found for -lPods
But only on Archive or Build for iosDevice, this is still working on the simulator.
Try removing armv7s from valid architectures section.
Build Settings -> Architectures -> Valid Architectures
I'm using Reachability on my project to get the type of connection used, but an error has ocurred.
Undefined symbols for architecture i386:
"_OBJC_CLASS_$_Reachability", referenced from:
objc-class-ref in ContributionViewController.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I don't know what to do... my project is for iOS 4.3 and I've never had this kind of problem before.
Thx
Did you include the reachability framework in your projects linked libraries ? You can confirm by clicking on your project file on the file list and checking the build phases tab. It should be listed in the linked library section,
