List(viewModel.Fill your Font name, Color, Size & Data Array with appropriate values. Yes, WhatTheFont is a simple and easy font finder that can help you identify fonts. To render a list of movies, we’ve built a MovieList view - which observes a view model and renders its various subviews like this: struct MovieList: View var viewModel: MovieListViewModel var selectedMovie: Movie? Since SwiftUI views are not concrete representations of pixels on screen, but rather lightweight descriptions of the various views that we wish to render, they often lend themselves quite well to being extracted into smaller pieces that can then be reused within various contexts.įor example, let’s say that we’re working on an app for browsing movies. changing font and its size of a picker in swift. This week, let’s explore that topic, and take a look at a few different techniques that can be useful in order to avoid trading Massive View Controllers for Massive Views. Pickers on SwiftUI Prior to adding our Picker, we need to make sure we understand State variables.

No view controllers, no problems, right? However, while SwiftUI’s overall design does encourage us to write more composable, decoupled code by default - it still requires us to design and factor our view code in a way that doesn’t put too many responsibilities on individual types. Now, as we’re collectively moving towards SwiftUI as the go-to framework for building UIs for all of Apple’s platforms, it might first seem that this problem will simply go away.
It’s so easy to end up with views that each represent an entire screen or feature - leading to code that’s often hard to change, refactor and reuse.įor UIKit-based apps (and to some extent AppKit-based ones, too), a very common manifestation of this problem is the “Massive View Controller” syndrome - which is when a view controller ends up taking on too many responsibilities, resulting in a massive implementation, both in terms of scope and line count. We already made an State property for this purpose, called numberOfPeople, so our next job is to loop over all the numbers from 2 through to 99 and show them inside a picker.

When writing any form of UI code, it can often be challenging to decide when and how to split various view implementations up into smaller pieces. Pickers, like text fields, need a two-way binding to a property so they can track their value.
