Apportable build errors when trying to convert a project created by SpriteBuilder

I created a New Project in SpriteBuilder and am trying to convert it to Android using Apportable.

When I run $ apportable build I am now getting many error: use of undeclared identifier errors related to CCLabelTTF.m. Here are three of them as examples:

/Users/name/Documents/TestApp/Source/libs/cocos2d-iphone/cocos2d/CCLabelTTF.m:350:50: error: use of undeclared 
  identifier 'NSForegroundColorAttributeName'; did you mean 'kCTForegroundColorAttributeName'?
if (![formattedAttributedString hasAttribute:NSForegroundColorAttributeName])
                                             ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
                                             kCTForegroundColorAttributeName

  identifier 'NSFontAttributeName'; did you mean 'kCTFontAttributeName'?

                                             ^~~~~~~~~~~~~~~~~~~

if ([formattedAttributedString hasAttribute:NSShadowAttributeName])
                                            ^

Any suggestions how to proceed?

I'm using

Xcode 5.0.2
Apportable release_1.0.30
SpriteBuilder 0.9.alpha.

Solution

The current version of Apportable does not have full support for NSAttributedString. That will be available in our new UIKit implementation, which we will release as soon as it is sufficiently complete.
