Embedding a Core Data model from a static library project

In one of my project, I want to share a Core Data model between 2 projects. I have a common static library project where the model and classes are defined.

Situation

• a common project that builds a static library which contains my Core Data model (to be shared with an iOS and an OSX project)
• my main iOS project

Problem

• static library cannot include resources
• how can I give make my main project use the Core Data model ?

Solution

• Create a new target of type Bundle (in OSX/Frameworks and Library)
• Change the build settings of this target:
• Base SDK:  Latest iOS 
• Supported platform: iOS
• Valid architecture: arm architecture
• Add your model file (.xcdatamodeld) to the Build phases / Compile Sources section of the bundle target
• Link your bundle with Core Data (add it to Build phase / Link Binary section)
• Build the bundle target

Now in your main project:

• Select the project to show Build Phases / Copy Bundle Resources
• Drag the Bundle target product (from Products group in the project navigator) to the Copy Bundle Resources section
• If it s not already there, add your static library: in Build Phases / Link binary section, use the "+" button to add your static library file
• Load the model from the bundle:

NSString *staticLibraryBundlePath = [[NSBundle mainBundle] pathForResource:@"ModelBundle" ofType:@"bundle"];

NSURL *staticLibraryMOMURL = [[NSBundle bundleWithPath:staticLibraryBundlePath] URLForResource:@"MyDataModel" withExtension:@"momd"];

model = [[NSManagedObjectModel alloc] initWithContentsOfURL:staticLibraryMOMURL];
