Here’s what the Apollo dev said about how he implemented it: https://old.reddit.com/r/apolloapp/comments/14lm3k4/i_just_released_an_important_apollo_update_that/jpzxc0f/

I can do a blog post something. I basically reimplemented that aspect of the navigation controllers and keep popped view controllers around in memory until the user pops something else on top of the ones that were kept around, that way you can always return. The tricky part was recreating all the animations and interactions to make it feel like it was still the iOS interaction.

So impressed by this app!

I can’t believe how fast this app got put together!

This is like muscle memory for me at this point so would love to get this feature back!

I’ve definitely done that like 20 times already on wefwef so having that implemented would be amazing. So far so good though!
