Removing App doesn't remove App Group data

Question

Ever since I started using App Groups to share Core Data between my App and a Today Extension/Widget I am having an issue. When I delete my app the core data maintains on the device, instead of being deleted like it used to.

I am aware this question has been asked before: Uninstalling app not delete app group data .Do I have to remove app group container and it's content manually?

The answer says it was a bug and Apple fixed it. I however still have the problem with iOS 9.2

How can I make sure that removing my app also removes the Core Data?

So in the end, I figured it out. A very old version of the app(Made with a different framework) was still installed on the test device, which happened to have the same App group.

Yeah, just discovered this, somehow once all apps that is in the AppGroup gets deleted, then the AppGroup data will be deleted. – Heilungkiang
