For last couple weeks, I’ve worked a lot about how to integrate RxSwift into an iOS project but I wasn’t fully satisfied with the view model. After reading many documentation and trying on my side, I’ve finally found a structure I’m happy with.

Since WWDC18, Apple made it way easier to developers to create model for machine learning to integrate iOS apps. I have tried myself in the past different models, one for face detection and create another with Tensorflow to fashion classification during a hackathon. Today I’ll share with you how I create a model dedicated to fashion brands.

It took me quite some time to get into Reactive Programming and its variant adapted for iOS development with RxSwift and RxCocoa. However, being fan of MVVM architecture and using an observer design pattern with it, it was natural for me to revisit my approach and use RxSwift instead. Thats what I’m going to cover in this post.

The delegation pattern is one of the most common design pattern in iOS. You probably use it on daily basis without noticing, every time you create a UITableView or UICollectionView and implementing their delegates. Let’s see how it works and how to implement it in Swift.

Part of the journey in software development is testability. Regarding mobile development, testability for your iOS app goes through UI testing. Let’s see different way to inspect any UI elements and prepare your iOS app for UI automation testing.

While wishing a happy new year around me, people helped me realised how many good things happened to me this year. Funny enough, while listing my goals for 2019, I found the matching list for 2018 and here is what really happened.

From my first year studying computer science, I’ve always wanted to do more on my free time and create simple projects that could be useful for others. I won’t lie, I wish I was able to monetise them but regardless the outcome, learning was always part of the journey.

During this year, I have blogged quite a bit about code architecture in Swift and I’ve realised that I didn’t explain much about which design pattern to use with it. In a serie of coming posts, I will cover different design patterns, starting now with observer.

For a while now, I really wanted to work on a machine learning project, especially since Apple let you import trained model in your iOS app now. Last September, I took part of a 24h hackathon for an Ecommerce business, that was my chance to test it. The idea was simple: a visual search app, listing recommended products based on a picture.

It has been couple months since my last post and despite the idea, a lot of things kept me busy far from blogging. Looking back, it all articulates around the same idea: why it’s important to always keep your skills sharp.
