dyld: Library not loaded different behavior for 6.0 simulator/6.0 device

Question

My app runs fine on the iPhone 6.0 Simulator in Xcode, but when I try to run it on my 6.0 device, I get the following fatal error:

dyld: Library not loaded: /System/Library/Frameworks/AdSupport.framework/AdSupport Referenced from: /var/mobile/Applications/26329A7C-04B0-415A-B8EB-3C59CC1EC0B1/hammerhead.app/hammerhead Reason: image not found

I am sure that my Phone has version 6.0 and is up to date. My deployment target is set to 6.0 in my project file and in my info.plist file. What should I do?

The problem seems to be with the AdSupport framework, which I put in my app so the new Facebook SDK (3.1) could function with iOS 6.

Answer 1

If you're targeting iOS versions less than 6.0, you'll need to make AdSupport.framework, Social.framework, and Accounts.framework optionally-linked.

Please have a look at the attached screenshot.

Cheers!!!

Answer 2

Solved my own problem: Set the frameworks that are giving you problems to "Optional" instead of "Required" by going to the project file Summary and scrolling down to Linked Frameworks and Libraries.

Answer 3

Same for CloudKit.framework on iOS 7 (it is for iOS8 only). Go to General > Linked Frameworks and Libraries, change CloudKit.framework to Optional. Thanks VSN.
