ARKit allow developers to layer virtual objects onto real world environment. In this post, we’ll explore how we can make our real hands interact with virtual objects using ARKit and Core ML, Apple’s machine learning framework. Augmented Reality Augmented…

RxSwift uses quite a lot of operators utilizing reactive patterns. It is a core part where its magic happens. The Clarke’s third law says: Any sufficiently advanced technology is indistinguishable from magic. In the previous article, we found out the basic…

When writing any kind of automated tests, it can sometimes be tricky to achieve a balance between making tests run efficiently and predictably, while still exercising the right code paths under realistic conditions. This week, let’s take a look at one way…

If you are struggling with massive view controllers you are likely to come across the suggestion to use container view controllers. A parent view controller splits a user interface into several, simpler, child view controllers. You add the root views of each…

Most of our apps present lists or grids of some data by using UITableView or UICollectionView. Often users can update this list by using Pull-to-Refresh technique or by pressing the update button. Everybody knows how to update UITableView by calling the reloadData…

Learn how to identify and remove degenerate state in your UIViewControllers and UIViews with Swift 5. This allows to significantly simplify your view controllers and views Swift code.

How to easily change between different views

Learn how to find and clean up unused localized strings from a String file. Find the keys which have no references and which can be removed.

Memory is leaked in an iOS app when the system is unable to determine if an
object allocated in memory is in use or not. The most frequent cause of memory
leaks in iOS apps are retain cycles. Check out my previous post for a more
detailed explanation of memory

Almost every program on the planet has to deal with strings one way or another, since text is so fundamental to how we both communicate and represent various forms of data. This week, let’s take a look at various ways to parse and extract information from…

After some times creating different iOS apps following an MVVM pattern, I’m often not sure how to implement the navigation. If the View handles the rendering and user’s interactions and the ViewModel the service or business logic, where does the navigation…

In the last article, we created a simple login flow using the bloc and flutter_bloc packages. If you haven’t checked it out already, you…

Custom transitions are a great way of controlling user focus. In this article we are going to implement come custom transitions using segues.

When testing delegates, we are asserting rigid implementation details. Here's a way to make those tests more flexible.

Christmas has always been one of my favourite times of the year. For me, Christmas is a season that brings so much love, laughter…
