Treat enum cases as if they were collections with a single move. — Enums are a vital programming tool in Swift, as they allow to define types that enumerate related values and therefore write code that’s safe and specific. As we all know, enum cases can be either simple, or with associated values that store additional data tied to them. Regardless, it’s often…

It’s not hard to mutate original provided arguments in functions, it’s just risky sometimes! — When coding in Swift, we usually don’t need to mutate the arguments that we provide to functions, and then make these changes visible back to the call site. We mostly use them as inputs to calculations or other expressions, and if necessary, we return some value from functions. But even…

Improve coding process by implementing simple and practical solutions — It becomes quite often necessary when implementing apps to create tasks that are either being repeated at a constant interval, or they are executed after a certain period of time. For instance, we might want to display a message for a few seconds and then make it disappear, or to…

No need to reinvent the wheel when what we need is just there! — It’s sometimes necessary either to enumerate, or to just count various components of a text in our apps. Examples of that would be to find the total number of characters, words, paragraphs, lines, and more in the entire or part of the text. Quite probably the first thought towards achieving…

It’s finally quite simple to fetch data easily in Swift! — Performing asynchronous tasks has always been part of the game when building applications for Apple systems. Up until not that long ago, closures and completion handlers had been the main way to handle asynchronous code. A -definitely better- alternative came with the arrival of the Combine framework and its declarative…

A quick way to override the default navigation style. — The navigation view has been one of the most essential visual elements in iOS programming, as it provides a default built-in mechanism to move back and forth between different views. In SwiftUI, it comes to get the place of the navigation controller that we’ve known from UIKit; navigation there takes…

Discover ways to write safer and more comprehensive code. — Not so long ago I discussed in this post about how to define enums with custom raw types in Swift. Creating enums with cases that can be either of a primitive data type, or a custom one as presented in that previous post, helps achieving a simple, yet quite important…

A technique to separate small view parts implementation quickly and easily! — SwiftUI provides undeniably a funny and innovative way to create user interfaces. We can get great visual results much faster and with less pain comparing to UIKit, despite any lack of features SwiftUI might still has. Usually, we tend to break complex views in smaller components, which, of course, is…

An additional way to use enums in Swift for smarter coding — As developers who write code for the Apple ecosystem in Swift, we use enums all the time in order to represent lists of values that are meaningful to our programs. Enums can contain simple cases, but quite often there are raw values matching to each case. …
