I'm using XCode 8.2.1 on a MacBook Pro using the most recent macOS.I just finished rewriting one of my early iOS apps in Swift to get it back on the store. It would be useful to some if it were available to run on laptops, so I thought it might be not too difficult to port it over to macOS.Right now, for some reason the zoom controls are not present or working for the storyboard, so you cannot back out and see a complex storyboard clearly. It makes it so awkward and slow work that I have suspended developing this app for macOS until this is fixed.This is such a major bug (which has been already reported by numerous developers, there is a whole discussion outside about this) that I would think it would get fixed pronto. But this doesn't seem to be happening.Is this just me, am I doing something wrong, is it MacBook Pro specific, or is there a workaround?

I'm building an app using SwiftUI, and am perplexed at why it seems so difficult to simply play an audio file that is in my assets. One would think it possible to write some code like: play(sound: "(name).m4a") but this seems unsupported. You must write elaborate, verbose code. Anyone comment on why it doesn't 'just work'? I understand that much more complex audio code requires more, but it seems that simply playing a file could be supported.

I have a current app in the store written in Objective C that works OK, but I want to update it via SwiftUI as a universal app. In my original app, I adjust the display brightness for night time use by setting UIScreen.main.brightness = 0.2 for example. When exiting the application, I return it to its previous value. I have been unable to find out how this can be done in SwiftUI. Anyone know?

I am being asked to write a pro bono app for a non-profit museum to allow an iPad Pro 2019 to provide a user-friendly interface on the iPad Pro so visitors can select video or pictures to be displayed via the USB-C connector on a large screen (presumably 4K) external monitor. No Apple TV. This is presuming they had a USB-C capable HD monitor, of course.This is different than simply mirroring the iPad Pro display. They'd like the iPad Pro display to stay showing all the options.It's unclear to me whether the current Apple iOS APIs allow this. You can do this on the Windows side from a touch-screen laptop, but I really don't want to go there. As a developer, I know I can code a beautiful user interface on the iPad Pro.We must determine this in advance before they buy the iPad Pro and monitor.
