This is the most horrifying error that I've dealt with so far. To be clear:

  1. This is in swift so it's not a ".h" ".m" issue
  2. My compile sources is so tiny, there are no duplicates there.
  3. I have redownloaded the SDK several times but it never works.
  4. The project only has two frameworks in it: FBSDKCoreKit and LoginKit

Any ideas? What is duplicated?

回答1:

Its an issue with the latest Facebook SDK (Sept 10th 2015). Download the release before it.

See this answer https://stackoverflow.com/a/32519847/1052084 which worked for me.



回答2:

thanks this working with me when using facebook SDK https://developers.facebook.com/resources/FacebookSDKs-iOS-20150813.zip



回答3:

This can also be caused by any included static libraries or sub-projects that are included with your project, having a different target version ie. you have an externalSourcesLibrary project and it's build target is set to minimum version 6.0 while your main project is set to something higher like 8.4 or vice versa.
