Accessibility is a very complex topic and as you start to engage with the topic, you quickly recognize how deep it’ll go. For this quick blog post, we’ll barely scratch the surface. I am not an expert and I likely will never be. I count myself lucky that Apple’s environment builds in a lot of […]
How to add a hover effect to a UITableViewCell (Swift)
When iPadOS 13.4 was released so was much improved Mouse-Pointer support. While a non starter on your iPhone, iPad with a trackpad and external keyboard quickly turns into a very capable computing device.

Today this feature is absolutely ambiguous and very easy to implement. For example, […]
Swift 4: JSON decoding with JSONDecoder() and structs
I have no apps in the app store, but a while ago I wrote an app for my own edutainment, which needed to parse JSON Data. At the time it was so darn complicated, that I enlisted Cocoapods and SwiftyJSON to help make things easier. SwiftJSON is pretty cool as it abstracts away a lot […]
Swift 4: Convert Unix Timestamp to a nicely formatted Date & Time
I needed to convert a Unix Timestamp, which for some inexplicit reason was being returned as a String by an API I was using and this is the super foolish function I ended up with.
