To be honest I distrust Microsoft with swift key, but the it recognizes the change in language just smooth. I could switch languages in one sentence and it would understand what I am writing just fine, no Sill suggestions
Apple recommending wrong words when you write in mixed-language was the case in iOS 15, so much I always needed to manually change my keyboard language. But it’s no more in iOS 17. As an example I just typed this entire comment in Turkish keyboard with English autocorrect and suggestions working.
Maybe the (most likely) AI-based thing requires some training though. I got my new iPhone a month or so ago.
SwiftKey is great and if someone distrusts Microsoft for it...then fine, but various different companies "control" various different parts of my phone.
With an iPhone, it's only one company, that controls every little thing, and we have no insight into Apple at all. They can basically do whatever the hell they want.
