Again, iOS isn’t Android — and that’s a good thing. But it’s hard to argue that iOS has a better notification system than its more open-source competitor. According to many, it’s the one thing that Apple lags behind on.
iOS 12 could improve this by adding notifications stacked by app, additional notification filters, individual rich notifications for iMessage, and improved interactions with notifications in general. Even adding the ability to change the notification sound for third-party apps would be great.
