I update cocoa pods to 0.38.1, and now i have problem with FBSDKCoreKit. When app starting it's stop on starting screen with error:
dyld: Library not loaded: @rpath/FBSDKCoreKit.framework/FBSDKCoreKit
Referenced from: /private/var/mobile/Containers/Bundle/Application/F88E950B-DE6A-4886-8491-BAA4F4477CE0/Yoop.app/Yoop
Reason: Incompatible library version: Yapper requires version 4.0.0 or later, but FBSDKCoreKit provides version 1.0.0
Who know how to fix it?
Try deleting your DerivedData Folder. Solved it for me.
