Hello, could you please suggest ways to implement BackHandler for iOS? Is it possible to use the native back swipe gesture in iOS?

[Alexander Zhirkevich]

You can follow this issue. Or embed Compose screens into native UIKit navigation when this critical bug is fixed

As an alternative you can write handle swipe on your side, like I do in my project.

FYI, Decompose supports the predictive back gesture on all platforms. There is one known bug which I will fix soon. https://arkivanov.github.io/Decompose/extensions/compose/#predictive-back-gesture

@Arkadii Ivanov Wow, predictive back is finaly there! Does // Your usual animation here means that i can make it slide like iOS native one?

[Arkadii Ivanov]

Yes, it's customizable

[Alexander Zhirkevich]

Great job! Thanks for your work

[Alexander Zhirkevich]

Not tested yet, but is there an api to block swipe from right side? =)

[Arkadii Ivanov]

Not currently. But that's a valid point, I will add this feature in the next release.

[Alexander Zhirkevich]

Thanks a lot! And what about appearing animation for previous child? Ios native one slides in from left

[Arkadii Ivanov]

Currently you can only customize the disappearing screen, which is customizable. I could also make the disappearing screen customizable.

[Alexander Zhirkevich]

Got it. Thanks once again, amazing job

[Arkadii Ivanov]

Thanks for the feedback! I have filed issues for those feature requests.

Just FYI, The new version of Decompose allows configuring transitions for entering and exiting screens individually. It's also possible to specify screen edges where back gestures should be handled.
