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.

You can display emphasized variants of system text styles using symbolic traits. In SwiftUI, use the bold() modifier; in UIKit, use traitBold in the UIFontDescriptor API. The emphasized weights can be medium, semibold, bold, or heavy. It is not always bold.

SwiftUI introduces the contentMargins view modifier, allowing us to shift a particular type of content in the view. The contentMargins view modifier is a crucial piece of the safe area management that was missing before in SwiftUI.

There are three ways to define the size of a column inside a lazy grid in SwiftUI. It can be fixed or flexible or adaptive. The most exciting option is adaptive. The adaptive option allows us to place multiple items in the space of a single flexible column.

The recent version of the SwiftUI framework introduces a trigger value pattern across its APIs. Trigger value allows us to attach a view modifier that runs its action whenever the trigger value changes.

Apple introduced the Accelerate framework many years ago, so it is available almost on every version of Apple platforms. It is a high-performance and energy-efficient way of doing computations using the vector-processing capabilities of the device.

Did you know that you can easily animate SF Symbols in your apps using the symbolEffect view modifier? I’ve used the heart symbol in my HeartRateView view and want it to bounce whenever its value changes to grab attention.

SwiftUI provides a way to keep the structural identity of our view hierarchy while changing the layout container using the new AnyLayout type. SwiftUI doesn’t recreate the views. It only moves them according to the new layout.

GeometryGroup view modifier isolates the geometry of the view and doesn’t animate every node of the view separately. Instead, it acts like a barrier and affects the whole view as a single item.

List automatically decors NavigationLinks with a trailing chevron. To achieve this behaviour in ScrollView, we can implement a custom ButtonStyle and apply it to the whole ScrollView.

Another interesting UI primitive I built is the SectionedSurface. It uses ForEach(sections:) which allows us to extract all the sections from the passed view and filter out the sections without content and add some paddings to section headers.

Group(subviews:) is a part of SwiftUI Container View API. This initializer of the Group type allows us to decompose the view passed with a ViewBuilder closure and wrap the whole view with a background with rounded corners to make it feel like a card.

One of the benefits of the data-driven Navigation API is the programmatic navigation with deep-linking possibilities. SwiftUI maps values of the mutable collection into a view hierarchy and allows us to push and pop views into the NavigationStack programmatically.

Why is a good app architecture essential when using coding agents? Coding agents have limited context windows and cannot store everything in memory. A well-defined architecture with clear boundaries is necessary to constrain the capabilities of your coding agent.
