Thank you, that helps. I’m still not clear on how to handle cases where ArrangementView decides to hide the secondary view. For example, imagine a video editing app using ArrangementView { VideoPreview, EditingControls }. If the arrangement collapses and hides EditingControls, the app is no longer fully usable. In this situation, what is the recommended way to make the secondary view accessible when ArrangementView collapses?

I had the same issue on macOS 27 with Xcode 27: app validation/upload would hang, and running xcrun swinfo directly also failed. Deleting the old ~/.itmstransporter folder fixed it for me. After that, retry validation/upload. My folder contained old Transporter files dating back to 2018–2019.

We filled a bug report FB20644893

Same here…

Thank you for your help!

Hi, It's a companion watch app.

Thank you for your response! The documentation is very helpful and also addresses other questions, such as the business model.

I duplicated your bug report (FB10786671). 3rd party camera apps will definitely be able to add media into the "Share Library".
