Issue #814 From iOS 14, TabView has the PageTabViewStyle that turns TabView into the equivalent UIPageViewController. We can of course implement our own Pager but the simple DragGesture does not bring the true experience of a paging UIScrollView or paging TabView. We can also use UIPageViewController under the hood but it’s hard to do lazy. Paging TabView in iOS 14 is built int and optimized for us. We just need to specify PageTabViewStyle, or just ....

Issue #806 Use runModal https://developer.apple.com/documentation/appkit/nsapplication/1428590-runmodalsession Blocks main queue A loop that uses this method is similar in some ways to a modal event loop run with runModal(for:), except with this method your code can do some additional work between method invocations. When you invoke this method, events for the NSWindow object of this session are dispatched as normal. This method returns when there are no more events. You must invoke this method frequently enough in your loop that the window remains responsive to events....
