I like this message as well. Note that at the moment there is (what I consider at the very least) a “bug” where the same message (mentioning overdrafts) is displayed even if you don’t have an arranged overdraft. More info: Overdraft charges notification and delayed transactions
For anyone wondering, the backend service responsible for sending this doesn’t know nor care which app you are using, so this message will be exactly the same on Android. 
Edit: I however wish this would be a proper feed item instead of a push notification, as it happened to me once when I opened the app without reading the message fully (and at least on iOS, opening the corresponding app clears all pending notifications), and not being able to see it again, thought my account was compromised and someone had set up a DD/Standing order without my permission. COps cleared it up but I still wish this notification would be persistent no matter how many times you open the app.
