It has been another few months since last Local Native v0.4.1 release, which was not able to include iOS version due to crashing in TestFlight. Now iOS v0.4.1 is finally released!
I still could not identify how the crash occurs by staring at the crash log.
It turns out the fix is to rewrite iOS code in SwiftUI.
Fortunately thanks to existing solutions for data flow, search bar, QR code, hiding keyboard, the rewrite is very pleasant and code becomes more concise by removing storyboard and view controllers.
One thing maybe a drawback from previous iOS version is that the bookmark note text is not selectable.
