Hi, I'm Sarun — an iOS developer.

A label might seem trivial, but it plays an important role in SwiftUI. Let's learn about this simple view.

iOS introduces a new concept to SF Symbols, SymbolVariants. Let's see how this improves the way we interact with symbols.

Initializing an NSViewController without nib isn't straightforward as UIViewController. Trying to do so would result in a runtime error. Let's learn how to do that.

We can use a frame modifier to make a view appear to be full width and height, but the result might not be what you expected.

If you are not ready to make your app support dark mode, you can opt-out of that. You can do disable it for an entire app or partially. Learn different ways to disable dark mode in iOS.

By default, when you set an image to an UIButton, it will position on the leading edge of the text. Let's learn how to put it on the trailing edge instead.

When you convert HTML string to NSAttributedString, sometimes, you will get an extra unwanted bottom padding. Learn what is causing this and how to mitigate the problem.

In iOS 15, we finally have native UI for a bottom sheet. Let's explore its behavior and limitation.

Swift 5.5 extends the support for the automatic synthesis to enums with associated values. Learn what can be expected from the synthesis code.

Learn how to make a case insensitive enum.

When you start a new project, you would see either of these attributes in an AppDelegate file. Let's find out its functionality.

In Swift 5.5, we can apply button style using leading dot syntax, .buttonStyle(.plain), instead of a full name of a concreate type, .buttonStyle(PlainButtonStyle()). Let's see how we can make our custom button style support this.

A tip for creating multiple schemes to quickly run your app in different languages.

Xcode has a feature to generate code coverage since version 7. Let's see how to enable it and what you can expect from this feature.

macOS is tightly coupled with storyboard and xib than iOS. To build your UI entirely in code, we have to do some initial setup.

Both Xcode and Simulator can simulate location, but they serve different purposes. The Simulator provided a quick and easy way to simulate location and movement. On the other hand, Xcode offers more customization. Let's learn the differences so you can pick the right tool for your needs.
