The framework makes logical assumptions, but if it isn't what you wanted, you can make modifications. SwiftUI then does it for you, making assumptions about some details. With SwiftUI's declarative UI, you'd just have to tell the framework that you want to group a button and two text fields in a vertical stack on-screen.
SWIFTUI GROUP VS VSTACK CODE
You'd need to write code for all details, such as: creating a vertical UIStackView element, adding it to the View, adding rules to center it on the X- and Y-axis of the root view, creating a UITextField element, and so on. Let's say you wanted to build a form with UIKit.
SWIFTUI GROUP VS VSTACK HOW TO
In other words, you tell the framework how you want your UI to look and work - and then it figures out how to accomplish your vision.Ĭontrast that with imperative UI (which is what developers had to deal with before iOS 13), in which you would have to specify implementation details and control every tiny detail. So, why is SwiftUI preferable to other user interface toolkits? Well, its main draw is that it allows you to design apps declaratively. With the release of iOS 13, developers gained access to the SwiftUI framework, which allows you to build a UI entirely with Swift code. SwiftUI offers a completely new approach to building UIs for iOS, macOS, and other Apple platforms. Alright, let's go.įirst things first, let's start with the SwiftUI basics.
I, instead, will try to make this article in Question-Answer format. There are already plenty of Apple SwiftUI tutorials with code and examples. SwiftUI lets developers write code in a declarative way. As you know, at WWDC 2019, Apple announced their new SwiftUI framework, which is supposed to replace the existing UIKit. Get a handle on how to use this modern framework, and you'll be able to build dynamic user interfaces for apps that run on iOS platforms:Īuthor's Note: Hi! It's Renat from Apphud – the best tool for analyzing iOS subscriptions. We'll also examine how SwiftUI differs from other UI frameworks like Flutter and UIkit. In this iOS SwiftUI tutorial, we'll break down the framework, examine its key features and benefits, list its challenges, and then give examples to show you how to navigate the latest version. Getting started with SwiftUI may seem intimidating, but it doesn't have to be. If you want to learn how to use SwiftUI and determine whether it's a good fit for your project, you've come to the right place. The SwiftUI framework plays into Apple's goal of getting everybody coding: it simplifies the basics and saves you time - which you can then invest into developing custom features. When Apple announced SwiftUI in 2019, it rocked the development world, with some people considering it Apple's most exciting piece of news since the announcement of Swift in 2014. SwiftUI is a powerful and promising framework that may well surpass UIkit in the future in terms of its robustness and reliability.
