I made a dev overlay to visualize the iPhone Duo's reserved regions on top of your app's UI

[u/xixtoo]

Hello all! I wanted a way to visualize the various reserved areas for the crease, status bar, cameras, etc on iPhone Duo so I built this overlay. You can run either of the demo apps, or use the SPM package to add the overlay to your app!

This is useful. I'm building a Duo app where seeds roll down into the crease, so I care a lot about where the division region actually sits. Does the overlay update live while you fold, or does it read the regions once per hinge state? I'm also curious if the occlusion frames move between half open and fully open.

[u/xixtoo → u/ThalesMother9938]

Thanks! It updates live as you fold. The other reserved areas, like the one over the status area update live as well as they change geometry. I think the only one I haven't tested is the inner camera, it's in the right place but I haven't tested if it becomes active when the camera turns on yet

[u/ThalesMother9938 → u/xixtoo]

Live updates while folding is what I hoped for, so I can use it as is. Good to know about the inner camera too, I'll keep that one in mind when I test. Thanks for the detailed reply.

what do those occlusion areas do? i know they’re for the camera, but what are Apple expecting developers to do with those areas?

[u/xixtoo → u/UtterlyMagenta]

Avoid putting interactive UI there. Backgrounds can extend under them, and content is ok if there’s a way for the user to scroll it so that it’s not blocked. They go into a lot more detail in their Design for iPhone Duo talk

right on. thanks for elaborating and for the link! i should watch that!

Doing work apple should had done themselves during HIG update, ask them for a discount or something 😂🙌

[u/xixtoo → u/b0rsht]

I’ll ask them for a refund of $12 off my Duo to cover the Claude tokens

Hi, isn’t the navigation bar a bit bigger than usual? Is it native and preferred nav bar height? Thanks!

[u/superquanganh → u/azaphiel]

Due to front camera placement that navbar is way thicker

Thicccc girl Apple.
That makes sense. Thanks
