I was going to comment on how is it possible to still have features from one OS not yet implemented in the other (because let's be honest it goes in both directions)
Autofill was an Oreo feature, so it checks out, Apple added it as well in the next release.
(Autofill as a feature has been there for way longer on Android but it was relying on accessibility, which was a bit hacky and pretty unsecure)
Most Android phones will never see it. I replaced my Moto G3 with a 6S Plus in part because I was tired of the lack of care from the manufacturers once the payment cleared.
I replaced the Android before it for the exact same reason. Motorola developed a good reputation, which was promptly torpedoed once it got bought.
I have plenty of issues with Motorola (and the Android OS update situation) but you bought a budget $250 phone. Not particularly surprising that the customer care and updates etc. weren't on par with a phone that retailed for 3 times that.
The Autofill API is an Oreo feature but password apps can draw over others and fill forms without it so it has worked on Android for years. It was one feature which meant I would never consider an iOS device, so good to see it implemented.
iOS had integration with 1Password before but it was slightly clunky and required a couple taps to get there.
I do like that each platform tends to stay up with the other for the most part, adopting the good ideas. I switched to iPhone to get the native call blocking API, which I believe in the next release Android adopted as well.
