I have this pet peeve where I don’t like to type out .compactMap { $0 } every time I want to remove nils from a publisher. Today I finally took some time to find a good alternative & I really like how ...

Last time we talked about how to refactor a callback based network call into an async/await based call. In that case, we had access to the underlying networking code & updated the entire chain of method calls to use async/await...

Recently I’ve refactored a few callback based network requests to use Swift’s new Async / Await syntax. Let’s take a look at how we can take a conventional callback based API method and improve its readability and simplicity...

Let’s learn how to add a slick app download banner to your website! Apple officially calls this a Smart App Banner, because it changes its wording based on if the user has the app installed. If the app isn’t installed, the...

Another SwiftUI post coming your way! This time we’ll take a look at Divider and how we can change its color. As nice as it would be to change the divider color with tint or foregroundColor, we can’t do it that way 😭...

I was recently working on my Wordie app & needed some confetti to celebrate a victory when the user guesses the correct word. I built the app completely in SwiftUI so I started searching for a confetti library I could drop in...

Going along with my previous post about auto incrementing build numbers in Xcode, I thought it might be useful to share how I debugged Xcode scheme pre & post actions. Normally these actions don’t show error messages...

If you're like me you probably get tired of manually incrementing your app build number in Xcode. After a few hours of testing I finally nailed down a simple solution that works on Xcode 13.2.1. Let's dive right in...

In step 1 we created the widget extension target & got it running on the simulator. Now let’s look at the basic parts of a widget. You’ll notice that Apple created a folder with your widget name & made a template file for you...

It was pretty cool when Apple gave us widgets with iOS 14. Finally we could customize our home screens with something more than just app icons! This is a simple walkthrough of how to add a widget to your app & what to put in...
