Lots and lots of interesting applications you can build with SwiftUI, including some very complex layouts that can be achieved with just a couple of widgets. Let's dive into construction of a dynamic list of Users, along with constructing HStack and VStack elements for our rows.

Brian, what would be nice to see is how you truncate a Text() in a VStack in a detailed View (not a List). I tried every possible way to have the lines stay in the frame, to no avail. Also trying to find out how an Image() in a VStack can take the full width of the screen instead of going overboard.

If you don't mind, when you have time, could you kindly show an example (if technically possible, of course) of how to build a macOS app using SwiftUI, please? I'm aware the code it's portable, but the look 'n' feel of an iOS app on macOS using SwiftUI is a bit "html style". Is it possible to build a UI like the Finder, for example, in SwiftUI? Or Interface Builder would be the quickest way to go? Many thanks in advance.

As far as your comment about the price of the pro display. Reference monitors are normally around $30,000 to $40,000. It’s for a specific market for specific use. So that being the case Apple is offering a great value to THAT SPECIFIC market. It’s understandable that to normal people not in that market it seems like an outrageous price. Both the Mac Pro computer and the Pro display are not considered expensive for the actual pros in that market who make enough on the work they do to cover it. Those tools are what enables them to do their work. Now about your video. Great job!

Hello thanks for the tutorial. I just want to pointing out that if you add some kind of NavigationLink around the UserRow's HStack (in order to show eventually a detail for the element) it seems that the multiline doesn't works anymore. Do you have any suggestion on this behavior? Thanks @LetsBuildThatApp

@LetsBuildThatApp 5 жыл бұрын

I think it does, you just have to apply some tricks

@hubrismaxim 5 жыл бұрын

Two comments: If your model conforms to Identifiable, then you can just pass it straight into ForEach; no need for the .identified(by:). Also, when you refer to brace syntax, it’s just trailing closure syntax on an .init() - of course it’s doing some magic in the background which is why you need to use the ForEach structure rather than plain for..in loops or switch statements.

So, dumb question: timeline for being able to use this in production apps? We have to wait until the new iOS is released, correct, and then, it'll work with the 80-90% of iOS users who adopt right away?

@hubrismaxim 5 жыл бұрын

Essentially correct. With one exception: it should work on the very latest releases of macOS 10.4 and iOS 12 - it works there currently and most people who are currently on the latest releases of those platforms are likely to upgrade right away so they should be a very small cohort.
