Hi, I'm Majid. I’m an indie developer building apps for iOS, watchOS, visionOS, and all other Apple platforms. I mostly build health-related apps like CardioBot, allowing you to understand and improve heart metrics. I try to share my experiences by writing blog posts.

UIHostingConfiguration is a new type of UITableViewCell or UICollectionViewCell configuration allowing us to embed SwiftUI views into a cell, but still use the performant dequeuing capabilities of the UICollectionView.

Empty and error states are part of almost every app, yet they’re often an afterthought. I explore ContentUnavailableView in SwiftUI and show how it helps you design clearer, more expressive fallback states with less code.

SwiftUI’s contentMargins modifier lets you inset only specific content like scrollable lists without affecting toolbars or scroll indicators — perfect for adapting layouts (e.g., centering content on iPad) while keeping UI elements where they belong.

LazyVGrid and LazyHGrid are two new view types that SwiftUI gives us to build a super custom grid-based layout. Grids allow us to create very complex and great layouts by mixing different types of GridItems.

SwiftUI’s alignmentGuide modifier lets us override standard alignments. We can align the bottom of Image and Text views in a horizontal stack. However, if an image has spacing inside a bitmap, it may not align well. Overriding an alignment guide will fix it.

SwiftUI provides you with a type called NavigationPath, allowing us to store any hashable value and map them to the destination in the navigation stack. NavigationPath erases the type of pushed values and allows us to keep values of different types.

All we need to play haptic feedback in a SwiftUI view is to attach the sensoryFeedback view modifier with two parameters. The first defines a feedback style, and the second is a trigger value.

You should be careful about the order of the passed views in ViewThatFits. It uses the first view that fits the available space. It means that you should usually place your views from the biggest to the smallest.

The task view modifier enables us to observe equatable data and execute the task whenever the data changes. By combining fields into an equatable struct, we can maintain a single task modifier that effectively cancels the task whenever any field changes.

SwiftUI provides us the keyboardShortcut modifier that we can attach to any view in the view hierarchy and define a keyboard shortcut. Pressing the defined keyboard shortcut is the equivalent to direct interaction with the view to perform its primary action.

TLDR about performances with Xcode Previews ⬇️ When you update: - an “inline” value: 🚀 - a stored property: 🐌 - a computed property: 🚀 So if you centralize your design constants at the top of a View for example, computed variables are the way to go 👌🏻
