How do I get the .xcdatamodel as a compiled resource into my pod?

TwelveTwentyToolkit.podspec

Pod::Spec.new do |s|
  s.name         = 'TwelveTwentyToolkit'
  s.version      = '0.0.1'
  s.summary      = 'The Twelve Twenty Toolkit of reusable Objective-C classes.'
  s.homepage     = 'http://twelvetwenty.nl'
  s.license      = 'MIT'
  s.author       = { 'Eric-Paul Lecluse' => 'epologee@gmail.com', 'Jankees van Woezik' => 'jankeesvw@gmail.com' }
  s.source       = { :git => 'https://github.com/TwelveTwenty/TwelveTwentyToolkit-ObjC.git', :commit => :head }
  s.platform     = :ios, '5.0'
  s.source_files = 'TwelveTwentyToolkit/TwelveTwentyToolkit.h'
  s.requires_arc = true
  s.preferred_dependency = 'CoreGraphics'

  s.subspec 'CoreGraphics' do |cg|
    cg.frameworks = 'UIKit','QuartzCore'
	cg.source_files = 'TwelveTwentyToolkit/CoreGraphics/*'
  end
  
  s.subspec 'CoreData' do |cd|
    cd.frameworks = 'CoreData'
	cd.source_files = 'TwelveTwentyToolkit/CoreData/*'
  end
  
  s.subspec 'AddressBook' do |uab|
    uab.frameworks = 'AddressBook'
    uab.dependency 'TwelveTwentyToolkit/CoreData'
    uab.source_files = 'TwelveTwentyToolkit/AddressBook','TwelveTwentyToolkit/AddressBook/Entities','TwelveTwentyToolkit/AddressBook/Entities/Abstract'
    uab.preserve_path = 'TwelveTwentyToolkit/AddressBook/TTUnifiedAddressBook.xcdatamodeld'

    def uab.post_install(target_installer)
      momd_relative = 'TwelveTwentyToolkit/AddressBook/TTUnifiedAddressBook.momd'
      momd_full = config.project_pods_root + momd_relative
      unless momd_full.exist?
        puts "\nCompiling TwelveTwentyToolkit/AddressBook Core Data model\n".yellow if config.verbose?
        model = config.project_pods_root + 'TwelveTwentyToolkit/AddressBook/TTUnifiedAddressBook.xcdatamodeld'
        command = "xcrun momc '#{model}' '#{momd_full}'"
        command << " 2>&1 > /dev/null" unless config.verbose?
        unless system(command)
          raise ::Pod::Informative, "Failed to compile TwelveTwentyToolkit/AddressBook Core Data model"
        end
      end

      File.open(File.join(config.project_pods_root, target_installer.target_definition.copy_resources_script_name), 'a') do |file|
        file.puts "install_resource '#{momd_relative}'"
      end
    end
  end
end

This is untested code. The idea is to preserve the path, compile it after installation has finished and manually add it to the install resources script. It's less than ideal, but this is (afaik) the first time someone needed a compiled Xcode Core Data model in a lib.

Note that the model is not added to the Xcode project from where it could be edited. Was that actually the intention?

Based on:

• https://github.com/HipByte/RubyMotion/blob/master/lib/motion/project/builder.rb#L415
• https://github.com/CocoaPods/Specs/blob/master/HockeySDK/2.5.2/HockeySDK.podspec#L26

Having it added to the Xcode project was indeed my original intent, sorry for the confusing title. Would that be 'easier' to do?

This would do however, if the code would run.
undefined local variable or method moms_full' for #<Pod::Specification for TwelveTwentyToolkit/AddressBook (0.0.1)> ~/.cocoapods/twelvetwenty/TwelveTwentyToolkit/0.0.1/TwelveTwentyToolkit.podspec:33:inpost_install'

No, making it available to the user in Xcode would make it harder. I’ve fixed the spelling error: moms_full -> momd_full

Right, now the compile hangs at Xcode I think, [...]/Pods/TwelveTwentyToolkit/AddressBook/TTUnifiedAddressBook.xcdatamodeld:0: error: Could not create bundle folder for versioned model at '[...]/Pods/TwelveTwentyToolkit/AddressBook/TTUnifiedAddressBook.momd'. Sorry for all this...

Did anyone figure this out? I'm still hacking away the ruby script above and it's just becoming a pandora's box... I'm thinking I might just implement the data model in code, using this resource: http://www.cocoanetics.com/2012/04/creating-a-coredata-model-in-code/

I was able to get a core data model integrated with the Pod I've been developing by using the podspec settings in this bug - basically it's:

s.resources = '[path_to_data_model_enclosing_folder]/*.{xcdatamodeld,xcdatamodel}' s.preserve_paths = [path_to_data_model_enclosing_folder]/*'

There's about zero documentation on this functionality, though, so your mileage may vary.

Take a look at the following:
