Xcode version: 7.3.1

iOS version: 9.3.2

Dependency manager + version: CocoaPods 1.0.1

This error message looks like either the wrong version of Realm's core library is being used, or Realm's core library is not being linked in at all. Can you please try the steps listed in our documentation on troubleshooting installation issues with CocoaPods:

pod cache clean Realm
pod cache clean RealmSwift
pod deintegrate || rm -rf Pods
pod install --verbose
rm -rf ~/Library/Developer/Xcode/DerivedData

+1 Thanks, Cleaning the build directory itself and removing DerivedData worked!

Also used the following: http://stackoverflow.com/questions/23616605/clean-build-folder-option-disabled-in-xcode-5

I've got exactly the same problem, over two projects.

I run a cocoapods install to update things, and it smashes a previously clean project to pieces...

It feels a little like it's something like the cocoapod version hasn't been built for arm64 or something...

The above mentioned troubleshooting issue doesn't solve it > <

Some more clues:

I get 107 warnings of this nature:

file:///Users/liam/Development/Project/Pods/Realm/Realm/ObjectStore/object_store.cpp: warning: Missing file: /Users/liam/Development/Project/Pods/Realm/Realm/ObjectStore/object_store.cpp is missing from working copy

Yet when I investigate the folder structure source is actually present in a different location:

@LiamInJapan please file a new issue if you'd like us to help you.

@bdash The problem pops up again with pod update to Realm 3.18. Downgrading to 3.17.3 works just fine. I tried cleaning pods as you suggested but didn't work. Thanks.
