I am using Xcode 6.1 with iOS 8.1 SDK to develop an iOS application.
SailracerEngine class imports SmoothSpeedTimeSeries and SmoothCourseTimeSeries classes to implement some of its functionality. Both are subclasses of SmoothTimeSeries. When I try to build my project, linker fails with the following error:
Undefined symbols for architecture armv7:
"_OBJC_CLASS_$_SmoothCourseTimeSeries", referenced from:
objc-class-ref in SailracerEngine.o
"_OBJC_CLASS_$_SmoothSpeedTimeSeries", referenced from:
objc-class-ref in SailracerEngine.o
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Other module in my code is using SmoothSpeedTimeSeries and SmoothCourseTimeSeries without any linker errors. How can this issue be solved?
The implementation file for class SmoothCourseTimeSeries has not been added to the Xcode Target.
If you click on the implementation file you should be able to see which Xcode targets it belongs to using the file inspector on the right.

I am using this framework in my app. i want to disable ARC For this Framework. it is having only .h files. Any solution
IOTCamera
it is showing this Error
Undefined symbols for architecture arm64:
"_OBJC_CLASS_$_Camera", referenced from:
objc-class-ref in PVPetLiveShowController.o
(maybe you meant: _OBJC_CLASS_$_CameraShowGLView, _OBJC_CLASS_$_Cameras )
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation
Your framework is already compiled. This is not related to ARC. Your framework is not compiled for arm64.
If you are using Xcode check this settings when you compile your framework
check that "Build Active Architecture Only" is set to NO (not as shown in screenshot)
recompile framework
I have just added 64 bit support for my iPad app in Xcode. Before the update i was able to archive the app with no red errors. After i add arm64 in the build settings get 2 error preventing the archive:
*ld: warning: ignoring file /Users/****/Documents/mApp/****/Pixate.framework/Pixate, missing required architecture arm64 in file /Users/****/Documents/mApp/****/Pixate.framework/Pixate (3 slices)
Undefined symbols for architecture arm64:

objc-class-ref in main.o
objc-class-ref in BaseView.o
objc-class-ref in BaseViewController.o
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)*
I have checked the framework and it is showing in the frameworks in the project.
I am currently using Xcode version 6.3.2 (6D2105)
The problem is related to third party framework Pixate.framework.
This framework is not built for arm64. That's why you got these errors.
How to fix it: find the version of this framework that was built with arm64 or just build it yourself by getting code from GitHub

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.
Today I have added to my project MWPhotoBrowser using cocoapods source control.
Tests in emulator where correct but when I start to test app on devices (ipode touch 5gen and iphone 4s) I got few issues:
ld: warning: directory not found for option '-L/Users/user/Pods/build/Debug-iphoneos'
Undefined symbols for architecture armv7s:
"_OBJC_CLASS_$_MWPhotoBrowser", referenced from:
objc-class-ref in KYMUFinalPageTVC.o
"_OBJC_CLASS_$_MWPhoto", referenced from:
objc-class-ref in KYMUFinalPageTVC.o
ld: symbol(s) not found for architecture armv7s
clang: error: linker command failed with exit code 1 (use -v to see invocation)
If you get this error with MWPhotoBrowser and you're in Xcode 6.1, then do this,
Go to your project -> Build Settings, and search for "Other Linked Flags" and add $(OTHER_LDFLAGS) to it.

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,
