MediumSwiftUI, Combine, OLX. Short story on fast adoption of SwiftUI…## Final ThoughtsSwiftUI is no doubt a revolution in how you create views. It’s easy, it’s fast to create. But it’s a beta. And while my heart is already in love, my brain says it’s not yet time. The demos, the first impression — it all makes you really excited, I’m a bit of an FRP fan so this fits right into my programming style. Unfortunately, as of now, there are still too many limitations. Too many pieces of the puzzle are missing to make this the right choice for your production app; no wonder — it’s still a beta! So, what is it that is missing? For example:* You can’t set navigation bar/tab bar colors.* You can’t set a *TabbedView*’s item title & icon at the same time.* You can’t build a SwiftUI project to Mac yet.* Combine is not yet fully integrated in Foundation.> The Foundation integration for the Combine framework is unavailable. The following Foundation and Grand Central Dispatch integrations with Combine are unavailable: KeyValueObserving, NotificationCenter, RunLoop, OperationQueue, Timer, URLSession, DispatchQueue, JSONEncoder, JSONDecoder, PropertyListEncoder, PropertyListDecoder, and the @Published property wrapper. (51241500)* There’s no way to watch the *Lists*’ offset (therefore no way to implement infinite scroll).* No SwiftUI way for a collection view (apart from hosting UIKit).* No way to change small details like *separatorStyle* in *UITableView.** I’m not sure there is a way to inject protocols as environment objects yet.We’ll get back to this in September at the Keynote… ;)If you want to get in touch, catch me on **Twitter** or by mail **aleksander.lorenc@olx.pl**## Resourceshttps://developer.apple.com/videos/play/wwdc2019/721https://developer.apple.com/videos/play/wwdc2019/204/https://www.hackingwithswift.com/quick-start/swiftui/https://developer.apple.com/documentation/swiftui/scrollviewhttps://developer.apple.com/tutorials/swiftui/The same call, in code.
