Speeding Up UIKit Development with SwiftUI UIKit Integration UIViewControllerRepresentable

Рет қаралды 26,182

Күн бұрын

One of my favorite features of SwiftUI is the ability to preview not only Views but also UIViewControllers in Xcode. No longer do we have to run the simulator a billion times when modifying UI elements inside our view controllers. Moreover, we can create multiple previews to make this process even easier to visualize what your final application displays.

Can you go the other way, though? If I have my app built on UIKit, can I add new ViewControllers I haven’t developed yet with SwiftUI and have it work well with my UIKit previous code?

Hi Brian! Awesome tutorial, but I have a question: what would happen at the time of previewing a ViewController which is actually fetching data from internet? Would the preview wait for the data and keep rendering in real-time after it, or will it just render the "default" state of the VC? Thanks in advance!

Although I will be on a trip in 2 years which kind of makes it useless for me ATM, this is literally something that is great. It makes complex collection views turn into a couple of lines of code. 90% of IOS apps are based around table views, this saves you a ton of time. Swift UI is not some random framework off the internet, it’s something that’s supported by apple.

@kidrainen01 5 жыл бұрын

Without using Swift UI, does anyone know how to get that feature where you have user profiles on top like that? For example I have a collection view that displays post, above the collection view I wanted to add a horizontal collection view that displays people to follow. How can I do this?

@Jason021376 4 жыл бұрын

So you build a UIViewControllerRepresentable struct to wrap around your UIKit viewcontroller, I get how displaying the UIKit ViewController is taken care of but what if the controller fetches information that you need to update other views. How would you get that information from the UIViewControllerRepresetable wrapper. For instance the UIKit viewcontroller you wrapped does some kind of REST call and you need that information to populate a SwiftUI list view. Don't know if I am asking this the right way

Hello Brain, I have been using Xocde 10, but i wanted to download Xcode 11 beta to create dummy projects and to try SwiftUI. But after i downloaded the Xcode 11 beta, i saw recent projects on launch screen were same. How can i seperate recent folders. Because i don’t wanna see my dummy project which i created on Xcode 11beta to appeared on my Xcode 10’s recent projects. Thank you so much

How would you use frameworks like AV Foundation with Swift UI Only? I know this framework is new and you might not know, and it is annoying for people to ask you these kind of questions when this framework literally just came out, but I just hope this makes you explore swift UI more!

SwiftUI previews is buggy sometimes. A quick restart fixes this bug for me. Also helps if the preview structs are not private.

How much does the lack of documentation, Q&A on stackoverflow, changing API's and the additional learning time cost you? It's not speeding up anything. Just like everyone learning swift before ABI stability was fucked you are for using SwiftUI in the next 3 years. Hint: Never use a technology less then 5 years old and 3 years after first large scale introduction. Bleeding edge is painful.
