"Undefined symbols for architecture x86_64:" Error with Branch.io

Question

I'm attempting to use the Branch.io iOS SDK in my iOS app, and I'm getting the following error when I try to compile:

Undefined symbols for architecture x86_64:
"_OBJC_CLASS_$_CSSearchableIndex", referenced from: objc-class-ref in BranchCSSearchableItemAttributeSet.o "_OBJC_CLASS_$_CSSearchableItem", referenced from: objc-class-ref in BranchCSSearchableItemAttributeSet.o "_OBJC_CLASS_$_CSSearchableItemAttributeSet", referenced from: _OBJC_CLASS_$_BranchCSSearchableItemAttributeSet in BranchCSSearchableItemAttributeSet.o
"_OBJC_METACLASS_$_CSSearchableItemAttributeSet", referenced from: _OBJC_METACLASS_$_BranchCSSearchableItemAttributeSet in BranchCSSearchableItemAttributeSet.o ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

As the tutorial described, I have the Branch-SDK folder correctly added to the project, I configured the PLST, and added all the code in the AppDelegate.m. I skipped step 3 for enabling universal links, because I won't need that yet.

What am I missing that could be causing this? For this sort of error with other frameworks, it tends to be caused by incorrect declaration of the class, but I don't see where I'm doing that incorrectly.

I suggest to verify if build only architecture is set to NO in the build settings. — tdelepine, Feb 18 '16 at 20:40
For "Build Active Architecture Only", Debug is set to "Yes", and Release is set to "No". — Andrew, Feb 18 '16 at 20:44
Under Build Settings, what do you have listed for **Valid Architectures**? Did you install the Branch SDK via CocoaPods, or manually? If manually, make sure all the Branch files are included in the target's Build Phases -> Compile Sources, especially `BranchCSSearchableItemAttributeSet` — Alex Bauer, Mar 07 '16 at 18:16

For me within the Podfile uncommenting the following line and rerunning the installation resolved this kind of issues in XCode:

use_frameworks!

And do a

pod install

And try cleaning and running the app in XCode once again and it should work. It worked for me.
