SwiftUI wishlist for WWDC20

We already started collecting our questions for Apple engineers. On the other hand, I decided to share with you my SwiftUI wishlist for WWDC20. This week we will talk about possible additions and changes in SwiftUI. I will show you also API that I expect to see during the next release of SwiftUI.

Mastering images in SwiftUI

This week I want to talk to you about another view component that we have in SwiftUI. Today we will deep dive into image view. Image view provides us a lot of nice features that we don’t have in UIImageView like rendering mode, resizing options, interpolation, etc.

Fitting and filling views in SwiftUI

This week I want to continue the topic of layout system in SwiftUI. The SwiftUI layout engine works predictably, and usually, an outcoming result looks like we expect. Today, to make this process even more apparent, we will talk about fitting and filling views in SwiftUI.

Template-view pattern in SwiftUI

Today I want to share with you a technique that I use a lot in SwiftUI. It helps me to solve the problem when I need to place a vertical or horizontal stack with equal-sized views that support Dynamic Type. I didn’t find the right name for this approach and call it template-view.

Building calendar without UICollectionView in SwiftUI

One of the most expected features of SwiftUI 2.0 is a SwiftUI alternative to UICollectionView. UICollectionView provides us an easy way to build super custom interfaces like calendar or photos grid. But today, I want to show you that we can create a calendar view without UICollectionView by using only pure SwiftUI.

The magic of fixed size modifier in SwiftUI

You may have seen some examples of fixed size modifier usage while trying to fix the issue with multiline text in SwiftUI. But do you know what exactly fixed size modifier does? How does it work? Today I want to talk about all the magic and power behind the fixed size modifier.

Catching errors in Combine

The Combine framework provides a declarative Swift API for processing values over time. It is another excellent framework that released side-by-side with SwiftUI. I already covered it multiple times on my blog, but today I want to talk about one of the key aspects of data processing. Today we will learn how to handle errors during data processing using the Combine framework.

Layout priorities in SwiftUI

This week we will talk about another core process in SwiftUI. We will learn the procedure of laying out views. We will understand how SwiftUI calculates positions and sizes of our views and how we can change that process using layout priorities.

Binding in SwiftUI

Binding is one of the several property wrappers that SwiftUI presents us to control data flow in the app. Binding provides us a reference like access to a value type. This week we will understand how and when to use binding. We will learn how to avoid common mistakes while using binding in SwiftUI.

Drag and drop in SwiftUI

Another iPadOS feature released in SwiftUI with Xcode 11.4 was the drag and drop. Finally, we can use drag and drop API not only with UIKit but also with SwiftUI. This week we will learn all about drag and drop interactions in SwiftUI.
