Writing an iOS 8 share extension without a storyboard

Question

Does anyone know of a good way to write an iOS 8 share extension without the MainInterface.storyboard that comes with the template?

Answer 1

Instead of the @objc hack, the proper way to do it in Swift is to include the module name in NSExtensionPrincipalClass, i.e.,

NSExtensionPrincipalClass
$(PRODUCT_MODULE_NAME).ActionViewController

(Documenting the error otherwise:

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[__NSDictionaryM setObject:forKey:]: object cannot be nil (key: ...)'

Hopefully will help someone who run into this error in the future.)
