One of the key features that was missing from SwiftUI when it first shipped was a good way to do programmatic navigation. There were some ways to handle this before iOS 16 introduced NavigationPath but it wasn’t very satisfying to use those APIs and they could be rather unreliable at times. To see an example, […]

By default, a NavigationSplitView in SwiftUI will show users an option to toggle the visibility of the sidebar. If you want to prevent this button from showing up so that users will always have to see your sidebar, you can do this by applying the toolbar(removing:) view modifier to your split view’s sidebar as follows: […]

Collections are a key component in any programming language. We often refer to collections as Array or Set but there are several other kinds of collections in programming like String (often a collection of type Character) and ArraySlice (referring to a part of an array). In this post, I’d like to explore two of the […]

In Swift, we sometimes want to assign a property based on whether a certain condition is true or false, or maybe based on the value of an enum. To do this, we can either make a variable with a default value that we change after checking our condition or we define a let without a […]

Swift comes with types of objects that we can use to write type declarations. They all have their own distinct features, upsides, and downsides. In this post I’d like to zoom in on the enum type so you can get a sense of what enums are, and when they can be useful. In this post […]

Apple has recently introduced a new requirement that makes it so that apps that use certain APIs for Apple’s mobile platforms (iOS, iPadOS, tvOS, watchOS) must declare their intended use of certain APIs. This requirement has gone in effect on May 1st which means that any app updates or submissions that don’t meet Apple’s new […]

Sometimes, we write code that needs set some state or perform some work at the start of a function and at the end of that same function we might have to reset that state, or perform some cleanup regardless of why we’re exiting that function. For example, you might have a function that creates a […]

In Swift, we can use computed properties to derive a value from other values defined on the same object. Being able to do this is super convenient because it means that we don’t have to manually make sure that we update derived properties every time one of the “source” values changed. We’ll just recompute the […]

In Swift, we can use the case keyword in multiple places. Most commonly, a case is used in switched but since you’re here, you might have seen a case in combination with an if statement. In this post, we’ll explore different places where we can use the case keyword to perform something called pattern matching […]

As teams grow and companies mature you’ll often find that it gets harder and harder to manage processes that seemed to be so simple before. When I worked in startups one of my favorite things was how quick the feedback cycle was on pretty much everything I did. When someone designed a new feature we […]
