Hi fjolnir, MikeF, Felensis, darsnack, enricobara
We're aware of the news and rumours about iOS 26.4. So far, what we've read is that it will add the ability to save to your wallet a credit card entered in a 3rd party app like Orion. At this stage it's unclear if the opposite (autofill of credit cards in 3rd party apps) would also be improved and better integrated. It would make sense to add support for this too, but you never know what Apple has in its plans...
In the meantime, you can already use the slightly more convoluted autofill contextual menu and navigate to your saved credit cards in any text field in iOS 26. Or as pointed out by JimG, you can use it on macOS too, but you have to set the text input into a text field before, in order to activate these menus.
So far we haven't seen anything similar announced or rumoured on macOS, but we'll keep our eyes and ears open for that platform too.
We have experience with Apple's AutoFill APIs (our team recently worked on OTPs and some edge cases on passwords), and they're not the easiest or most documented APIs. We'll have to wait for the release of iOS 26.4 to evaluate how to add any new capabilities to Orion for iOS.
Rest assured we absolutely want to implement this feature. In the meantime, we thank you for your patience.
