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.

Couple months ago, I’ve build an app and released it on the App Store. Since published, I really wanted to see how it lives and understand how to make it grow. Ideally, I wanted to know if there is a product / market fit. In the article, I describe each steps and ideas that helped my app grow and what I learnt from it.

Most of mobile apps interact at some point with remote services, fetching data from an api, submitting a form… Let’s see how to use Codable in Swift to easily encode objects and decode JSON in couple lines of codes.

I recently went for a Swift conference and UI automation testing was one of the subject. I already mentioned it with Appium in the past but I think it’s time to go back to it and explain why today I still prefer using Apple’s testing framework instead.

I recently implemented 3D touch for an app and I was very interested about home screen quick actions. If it can be a good way to improve user experience, it doesn’t mean your app always needs it. In this article, I explain how to add home screen shortcut for your app in Swift but mostly why can justify implementing it.

I recently realised that my first blog post was 6 years ago. It’s a good occasion for me to do a little retrospective and share what I learnt from blogging over the years.

If you care about user experience, error handling is a big part you have to cover. We can design how an mobile app looks like when it works, but what happen when something goes wrong. Should we display an alert to the user? Can the error stay silent? And mostly how to implement it the best way with your current design pattern? Let’s see our options while following MVVM pattern.

The best way to learn and become more creative as a developer is to focus on a side project. A really good friend coming back from Japan came to me with an idea when I needed that side project. This is how we created Japan Direct, from the idea to the App Store in almost no time.

For the last couple weeks, I tried to step back on my development to analyse what is time consuming in mobile development. I realised that most of new views are based on same approach, reimplementing an similar structure around a UICollectionView or UITableView.

What if I can have a more generic approach where I can focus only on what matters, the user experience. That’s what I tried to explore in this article.
