I keep on getting the following error: <pre class="prettyprint"><code>duplicate symbol _llvm.embedded.module in: /Users/name/Documents/FacebookSDKs-iOS-20150910/FBSDKCoreKit.framework/FBSDKCoreKit(FBSDKApplicationDelegate.o) /Users/name/Documents/FacebookSDKs-iOS-20150910/FBSDKCoreKit.framework/FBSDKCoreKit(FBSDKServerConfiguration.o) ld: 102 duplicate symbols for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation) </code></pre> I've tried deleting the FBSDK and reinstalling, but that has not work. I also suspect that the fact that I'm bridging the framework into Swift may be the problem. My bridging header contains the following: <pre class="prettyprint"><code>#ifndef EggCrush_Bridge_h #define EggCrush_Bridge_h #import <FBSDKCoreKit/FBSDKCoreKit.h> #endif </code></pre> My AppDelegate.swift file imports FBSDKCoreKit. There are no other linker flags. I'm running Xcode 6.3.2 and building a project for iOS 8.3 How to clear this error up?

This thread explains you must compile the Facebook 4.6.0 SDK in Xcode 7 to resolve the issue. After compiling in Xcode 7 it worked for me. In the Facebook iOS SDK 4.6.0, App Thinning (Bitcode) support has been added and therefore it cannot be complied in Xcode versions lower than Xcode 7.0.

I keep on getting the following error:

How to clear this error up?

What is undefined symbols for architecture x86_64?

Why Is the Undefined Symbols for Architecture x86_64: Error Happening? This error is happening due to the lack of included values inside the declared statements in your code. The browser is going to render the information incorrectly and show this error, especially if you are working with Main and Similarity tools.

If not mistaken, you are using the sdk which just released by Facebook at September 10th, 2015 which named as FacebookSDKs-iOS-20150910.zip. Try to use sdk that released at August 13th, 2015 which named as FacebookSDKs-iOS-20150813.zip and report to Facebook about the duplication problem if you can. Thank you.

This thread explains you must compile the Facebook 4.6.0 SDK in Xcode 7 to resolve the issue. After compiling in Xcode 7 it worked for me.

In the Facebook iOS SDK 4.6.0, App Thinning (Bitcode) support has been added and therefore it cannot be complied in Xcode versions lower than Xcode 7.0.
