Get version number of iOS Universal Framework in client

This is likely not limited to iOS Universal Frameworks but all xxx.framework files. However I can't seem to find documentation on how to get the current version and build of a framework within the client application. Within an app you'd use something like:

NSString *name = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleDisplayName"];
NSString *build = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleVersion"];
NSString *version = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleShortVersionString"];

That would give you the current information stored in the Info.plist for the app. But how to we find that information for a framework. And in my case, specifically an embedded framework.

Answer Source

I have found that Apple's new Cocoa Touch frameworks supported in Xcode 6, offer an easy answer to this problem. In the default header file created for you, something like Framework.h, you'll see two constants declared for you. These are defined later presumably at runtime by internal framework logic. But I have confirmed they're pulled from the plist for the framework.

//! Project version number for LocalSearch.
FOUNDATION_EXPORT double FrameworkVersionNumber;

//! Project version string for LocalSearch.
FOUNDATION_EXPORT const unsigned char FrameworkVersionString[];
