iOS 8 Beta Today extension widget not showing in a Swift app?

Question

Today extension doesn\'t show up in a Swift app, but it does in a Objective C app.

What I did was to add a UILabel with some content on the storyboard for the swift

Answer 1

Xcode6 is beta and this is a bug with it, you will have to wait for a new release.

Answer 2

An app extension target must include the arm64 (iOS) or x86_64 architecture (OS X) in its Architectures build settings.

See Apple's documentation

Answer 3

The problem for me was that the extension's deployment target was set to a different version than my app's target. You should confirm the extension's target is set appropriately because it may target a different version.

Answer 4

You can comment out the supplied init method.

//    init(nibName nibNameOrNil: String?, bundle nibBundleOrNil: NSBundle?) {
//        super.init(nibName: nibNameOrNil, bundle: nibBundleOrNil)
//        // Custom initialization
//    }

This will allow your extension to run properly. The issue seems to be caused by differing initializer behavior between Swift and Objective-C. Removing the above initializer will inherit all of the required initializers from the superclass.

Found that solution on the apple developer forums for your reference.

Note: You may have to Clean and Build your project after doing this before the changes will have any effect

The extension is actually crashing, with an error like:

fatal error: use of unimplemented initializer 'init(coder:)' for class 'com_blabla_blabla_MyTodayExtension.TodayViewController'

This indicates that another option would be to implement:

init(coder aDecoder: NSCoder!) {
    super.init(coder: aDecoder)
    // Custom initialization here
}

if you want to retain the ability to do custom initialization.
