I\'ve been working on getting \"custom skinnable\" interfaces working for my iOS app by bundling up xibs and downloading bundles, and loading the xibs in those bundles.
After a good amount of time I figured out that this is a commonly faced problem of loading the resources via library. I was missing the step to add "CoreFramework" to link into the resource bundle and also was not copying it to the client application folder. These steps will help loading the resource bundle appropriately. #dsiddhapura's hint helped me identify these issues.
