The singleton pattern is very quick to implement, especially in Swift, and it works well. As your users navigate through the screens of your app and interact with it, you need to keep a global state that tracks all the changes the user makes to the data.Īnd this is where most iOS developers reach for the obvious, but incorrect, solution: the singleton pattern. State propagation across view controllers is vital in any iOS app. I myself have fallen into this trap in the past. One of the most common iOS development bad practices arises when passing state between the view controllers of an app. I realized that, like many iOS developers, I had succumbed to some classic pitfalls of bad coding practices. From then on, the problems in my code started to stick out like a sore thumb. Not much later, I started reading about some best practices. I had the typical developer hubris: we often think that what we do is great and others don’t get it. I dismissed their judgement, thinking that my code was great and there was no way it could be improved. Although they said the quality of the code was not bad, they pointed to the fact that the code was hard to maintain and to test (unit testing was not very popular in iOS development back then). On the first run, you will need to add your extension to the share sheet. Once the extension starts running, select a photo and tap on the Share button. When their response came back, the verdict was different than I thought. When suggested to choose an app to run, choose Photos. Select some content, Control-click to reveal a contextual menu, and choose Share. That didn’t bother me, because I thought my code was impeccable and that the review company would say the same. View the Social area in Notification Center. Part of this process involved sending the code of the app I wrote to a third party for review.

Big companies, especially banks, usually have processes in place to ensure that their software is secure, robust, and maintainable. A few years ago, when I was still an employee in a mobile consultancy, I worked on an app for a big investment bank.
