In today's video I show you how to create a List with a custom cell in SwiftUI. We also create a NavigationView that allows us to navigate to a detail view while passing data. You will learn how to create a link button that navigates to safari as well as some basic refactoring. This tutorial was created in Xcode 12.4 and Swift 5.3.

Another commenter posted "Don't know if this is only my problem, but I needed to add the line .listStyle(.plain) after the List and embed the Image and VStack in a HStack. Otherwise, it looks a bit messy." I had the same issue and the above fixed it for me. So verified :)

@9:40 if your version doesn't have the Text views to the right of the Image view, then wrap the Image view and VStack in an HStack. Seems Sean is using a different version, I'm on Xcode 13 Beta 5 and the Text views were below the Image view. Wrapping them in an HStack, solved the problem. Seems the older version had an implied HStack.

As always, great content Sean! You have definitely been one of about 5-6 KZfaqrs that have helped me become a "real developer" in Swift. Still lots to learn, but starting to realize that I know so much more than I did when I started last July. But I love your teaching style so much that I will definitely be a customer for your new course coming out next week! One tip..when you are extracting that Subview you can rename it right there rather than going back and doing so. It's easy to forget...I do it all the time...but easy to see someone else doing it LOL! (I know you are focused on delivering the best explanation while recording! I don't have that excuse...)

@rdtba21qw 3 жыл бұрын

As always, so good Sean. I often come back to your videos and rewatch them before building out a particular feature. Super clear and concise with some great tips. Much better than wading through my own ill written notes on the subject ;-) Thank you!

@seanallen 3 жыл бұрын

Thanks for the kind words, Robin. I always recommend repeat viewing of content. At least in my experience, going through a tutorial, blog post, or video only once isn't quite enough for the concepts to sink in. I usually have to go through the content, try to implement it myself, then rewatch the content for it to really sink in.

Great video as always! SwiftUI works like magic until it doesn't... As soon as one wants to do some customization, it seems it lacks the necessary tools... SwiftUI is for sure the future of iOS development, but it is not the present. Compared to UIKit, it looks a bit more than a toy. Easy and fun to use, but for serious stuff, the good old UIKit is still on top. Regardless, keep up with the great work!
