I think the best way to get more knowledge about an API is to do a real project with it. So to improve in SwiftUI, I decided to convert one of my hobby projects, FontMetrics, to use it. FontMetrics is a straightforward application that lists all the fonts available on iOS and visualizes the typography metrics…

So you may think we finish the work on the isMuted property on part 2 of this series? Not quite. Start the demo app, notice the mute icon on the top right of the video controls, what happens if you tap on that control? Sure thing it will mute our video, but notice that our…

On the previous article, we created our Video component for SwiftUI. It was working correctly, but there was not a lot of configuration you could do to it. For example, if you wanted to mute the sound of the video, there was no way to achieve that with our current component. Let’s see how we…

Originally posted on Mobile.blog: The best technology is invisible and reliable. You almost forget it’s there, because things just work. Bad technology never disappears into the background — it’s always visible, and worse, it gets in your way. We rarely stop to think “My, what good Wifi!” But we sure notice when the Wifi…

Recently I have been tinkering with SwiftUI, the new UI framework from Apple.  I’m enjoying the declarative approach, the ability to have real-time previews, and that all settings are save in code (bye, bye Interface Builder). While this new framework has a lot going for it, it still doesn’t have the same depth of functionality…

Last week I attended UIKonf 2019 at Berlin. This year conference had an all-female speaker line up, and I think this was an excellent idea to help increase gender diversity on our profession. A lot of female attendees commented they felt inspired to have the opportunity to see so many great presentations delivered by female…

Last year Automattic, the company that I work for, bought the .blog domain  and being a generous company they decided to offer to all automatticians  the domain of their choice! So say hello to my new domain: sergio.blog !! So from now on I will start using this new home for my personal writing:  travel, review…

I spent the last week watching Apple WWDC videos, and after downloading Xcode 8 I was testing several of my libraries and applications. While testing the WPMediaPicker library I found that the sample app was crashing every time I opened the picker. After some investing on the code I found that the app was crashing the…

Some time ago when Swift was announced there was a big discussion in the iOS development community about JSON deserialisation and the right way to implement it. At the time, I didn’t give it much attention because I was still committed to Objective-C and didn’t have any immediate requirements to use Swift. Fast forward two…

I had a great time on WordCamp Edinburgh 2015, met some great people from the local WordPress community and enjoyed some great talks from the other speakers. Here is the video of my presentation about the WP-REST API and the slides: The code for the app  show in the presentation can be found on this GitHub repo. I…

Excellent articles from Martian Craft about the new San Francisco font on Apple devices: Why San Francisco Arriving At San Francisco A must read for all designers and developers working on the platform.  

If like me you got excited about the new tvOS platform that Apple launched last week, here are some mandatory documents to read before you start coding away: Apple TV Human Interface Guidelines Apple Programming Guide for tvOS While you read this you can download Xcode 7.1 beta that includes the tvOS SDK. After you…

While developing for iOS one of tools that I missed a lot from my C# projects  was FxCop. FxCop was a tool that analysed your assemblies and reports information about the assemblies, such as possible design, localization, performance, and security improvements.  On Xcode the only similar tools is the static analyser but it’s scope its…

One of the big pains of Android development was the lack of a fast Android emulator to test apps. Until recently to do any kind of development you need to own a actual device and with the fragmentation on Android this could very expensive… Say hello to GenyMotion a company that provide super fast emulators. They…

Until recently if we wanted to have continuous integration for your iOS project we needed to create your own solution, normally it involved the creation of a Jenkins instance in a MacMini. Now with  Xcode 5 and the OSX Server we also have an official Apple alternative in the form of Xcode bots, but you still…

The fine guys from CocoaPods now provide us CocoaDocs a tool to search and view documentation for most  the libraries that are available in their pods repository. The best thing is that if you have a library and its configured to to be a cocoapod the documentation is automatically generated for you. The index page…

One very common pattern when implementing Objective C singleton objects is the sharedInstance method. Because I was a bit tired of repeating this code in several of my classes I decided to implement a Xcode Code Snippet that can be reused everywhere. As you can see simple code that can be apply to any object.

Here is a good write up, from Mike Ash, about the preprocessor and the proper way of writing macros. And here is a good example of a better Assert macro.
