iPad 1 dyld Fatal Error

I am building an Xcode project with Unity3D to multiple devices. The app runs fine on an iPhone 3GS, iPhone 4, iPod Touch 5, and iPad 4.

Earlier builds ran fine on an iPad 1. However, the current build will not run on the iPad 1, showing the error:

dyld: Library not loaded: /System/Library/Frameworks/Social.framework/Social
  Referenced from: /var/mobile/Applications/F64896A2-EDCB-458A-9927-B86DF3F06E5A/myapp.app/myapp
  Reason: image not found

I have made sure that the Social.framework Framework is being linked (and set to required). I am building for arm6 + arm7, targeting iOS 5.1. The iPad 1 runs iOS 5.1.1. I am using Xcode 5.0 and Unity 3.5.7.

What could be causing this issue and how can it be fixed?

Thanks,

Solution

  • The Social Framework is only available in iOS 6 and later. iPad 1 only supports iOS 5.1.1. For reasons I've never fully understood, the compiler doesn't catch this and let's you try to do things that you shouldn't be able to.
