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?

When I delete the fi

Answer 1

Can't add a comment but it is no longer NSPrincipalClass rather it is NSExtensionPrincipalClass

Answer 2

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

<key>NSExtensionPrincipalClass</key>
<string>$(PRODUCT_MODULE_NAME).ActionViewController</string>

(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.)

Answer 3

Found the answers from these answers combined Answer 1 and Answer 2.

For Objective-C you will have to put the following in the info.plist of the App extension: NSExtensionPrincipalClass and make sure that it is under NSExtension Dict

So full answer should be like this , in my case ActionViewController is the App extension viewController

Answer 4

Figured it out!

Turns out there's a weird module naming thing going on in Swift, so you can fix it by adding an @objc name to the class:

@objc(PrincipalClassName)

class PrincipalClassName: UIViewController {
...

and then set the NSExtensionPrincipalClass key to PrincipalClassName.
