Unable to set deployment target below OSX 10.8 (Error: dyld: library not loaded - Reason: incompatible library version)

I am trying to create and run an OSX application with Cocoa. However, when I try to set the deployment target to anything other than 10.8, I get a runtime error when the application tries to start:

dyld: Library not loaded: /System/Library/Frameworks/ApplicationServices.framework/Versions/A/ApplicationServices Referenced from: /Users/chris/Library/Developer/Xcode/DerivedData/Build/Products/Release/MyApp.app/Contents/MacOS/MyApp Reason: Incompatible library version: MyApp requires version 64.0.0 or later, but ApplicationServices provides version 1.0.0

As far as I can tell, there is nothing in my application that uses anything from ApplicationServices.framework. I don’t even know why he will try to download this library.

For reference, I use several third-party frameworks, including Growl.framework (Growl 2.0), Sparkle.framework (Sparkle 1.5 b6) and MagicKit.framework (https://github.com/aidansteele/MagicKit)

Answering my own question (after several hours of investigation):

Apparently, when contacting CoreGraphics.framework in my desktop application project, he triggered a runtime download request for version 10.8 for the ApplicationServices platform. Fortunately, I did not even use anything from CoreGraphics. Uninstall stopped the error while loading dyld.

Make sure ApplicationServices.framework is added to the Link Binary With Libraries Phase on the Configure Phase tab.

I got this error when trying to use characters in CoreGraphics and import <CoreGraphics / CGGeometry.h> directly, instead of the recommended <ApplicationServices / ApplicationServices.h> as stated in the documentation.

Believe it or not, even in 10.8, you still have to import AND bind ApplicationServices for this.
