Understanding async/await is a pre-requisite to read this article. If you aren’t familiar with that concept, feel free to read the first part of this article series: Understanding async/await in Swift.

Before you try to dive in with concurrency in Swift, you need to understand async/await. There’s no way around it. While async/await are not the only concurrency options, Apple’s SDKs are starting to make heavy use of them. There is no doubt that third-party library providers will start offering these as well.

This is a tutorial series focused on the new async/await APIs Apple introduced in WWDC2021. I do not know how many articles it is going to have yet, but they will be posted in the upcoming weeks.
Having our apps have good reviews is generally a good thing. After all, many users look into how many stars an app has before deciding on downloading it. Apps with a general poor rating may not get many downloads (unless they are “essential” apps of any kind, such as companion app to another service).
We all as developers have experienced that users are quick to give a one-star review when something doesn’t work right, but they are never inclined to rate 5 stars when they are satisfied with an app.
This may sound surprising to you, but even though we have app autoupdate on iOS now (and we have had it for a very long time), many people don’t have it on, or the system simply doesn’t prioritize app updates because users don’t prioritize it enough. In fact, in my day job, in which I maintain a user-facing banking app, the vast majority of users are not even in the latest version. The most used version is the one we released in April, and we average one release per week for bug fixes alone, and about monthly for major new features.
As SwiftUI is still relatively new, and it is not clear yet for many people how to use MVVM on iOS, I decided to write this short article in which I explain how one would integrate Face ID/Touch ID with SwiftUI.
Let’s remember that SwiftUI uses the MVVM design pattern over the traditional MVC, and this can be confusing for people who are migrating to the new pattern for the first time. That said, the main takeaway from this article is to understand that views get destroyed and rebuilt very often in SwiftUI, and therefore the right place to write this kind of logic is in the ViewModel
Somehow, this shiny new object, which was actually introduced in iOS 10, flew past my radar. Today I want to take a few minutes to talk about the NSDateInterval object. This object allows us to quickly calculate the time interval (represented as a NSTimeInterval) between dates, it allows us to check if two dates overlap, and it allows us to check if a given date is within a certain interval.
Ah, print. Probably the most known, the most used, the most popular debugging tool, and probably the most loved line of code of all time. You have undoubtedly used print before, if not in Swift, in other languages. The vast majority of programmers have started their software building skills with a print or equivalent somewhere.
We have all used print before, but this short article is about using the function to the max - it actually has a secret or two you might not know about.
We have all worked with strings before. Printing a piece of text, or displaying some information to users in a label, can all be done in strings. But regardless of how popular strings are, they actually have a lot of complex or unknown functionality that can help developers, but they struggle to see the light of day.
In this article, we will explore a very interesting aspect of strings in Swift: Raw Strings, what they are, and how they can be helpful to your every day job.
