I have built a cocoa framework via XCode 6.1.1, also created a universal version of the framework, then when I import the framework into a project, an compiling error:
Undefined symbols for architecture armv7:

ld: symbol(s) not found for architecture armv7

Wonder to know why?
And how to analyse the cause of the problem?
You have to add the armv7 architecture to your framework before building it.
Because the project where you use the framework in has this architecture.
You also can check the path to the framework (framework search-path)

While building the Application i am getting the following error i have searched a lot but i am unable to figure out what is the problem.

I am using GoolgeMaps SDK 1.4.3
PS:- I am relatively new to iOS programming so please avoid any blunders.
Adding value $(inherited) to BuildSettings->Linking->Other Linker Flags of your target
If you are developing an SDK/framework/POD you should do the same as above but under target name PROJECTNAME_tests.
Should fix the issue.
I had this problem too, and my solution was to add the frameworks to
Target -> Build Phases -> Link Binary With Libraries
ok I figured out the Problem
My Library was not built for 64-bit but i was trying to use that settings for my app, after i removed arm64 from architecture i successfully build the application.
I'm relatively new to iOS development. I'm not sure what to do about resolving the following errors that I believe are due to referencing a bluetooth library. What can I do to debug/fix this?

I haven't done Bluetooth related development on IOS but the messages might be related to the missing Bluetooth framework in the project files.
Have you added them ?
IOBluetooth.framework
IOBluetoothUI.framework
I am new in phonegap app development in iOS. After adding CordovaLib.xcodeproj in my xcode project, I made architecture changes in buildsettings as suggested here. Other linker flag is -all_load and -Obj-C When I build the project, I get Apple Mach-O linker errors described below. I have not mentioned i386 anywhere in my build settings. How do I negate this error?

I am integrate LinkedInIOS Login Demo with my current application from:
https://github.com/jeyben/IOSLinkedInAPI
Also add supporting classes of "AFNetworking".
And It's gives me an error as mention below:

Please suggest me any solution about it. My deployment target was 5.0.
That problem was resolved. As possible issue for that kind of problem was shown at below question:
https://stackoverflow.com/questions/6429494/...
But in my case I need to add MobileCoreServices.framework
By adding this framework problem was resolved.
Thanks.
I need some assistance. I added Parse SDK and it works fine during testing. When I attempt to build it, it gives me four 'Apple Mach-O Linker' errors:

It sounds as if your library is not built for 64-bit iOS but you're trying to use that setting for your app. Try removing arm64 from the architecture entry in your build settings.
Cleaning the code and then building again solve the problem for me!
