I've been mentoring junior developers for years. It's one of the most rewarding parts of my job. Watching someone go from "I don't know how to write a for loop" to "I just shipped a feature that thousands of people use" is incredible.

This week's iOS development journey took me deep into two notoriously challenging areas of iOS development: audio engineering and background task management. What started as a seemingly simple volume slider issue revealed layers of complexity that showcase what real-world iOS development truly involves.

I'm excited to announce a significant pivot for my podcast AppForce1, transforming it from a weekly news format into what I'm calling the "AppForce1 Work Log." After a stint in developer relations at Stream, where I spoke at conferences like NS Spain, Swift Heroes, and AppDevCon, I've returned to my true passion – building iOS apps. I'm now working at Dawn Technology (formerly eGenic), the company behind the AppDevCon conference, where I'm focusing on actual development rather than just talking about it.

As someone who spends the majority of their day coding, reviewing content, and collaborating with a remote team, my desk is more than just a workspace—it’s mission control. And over the years, I’ve learned that the details of your setup can make or break your productivity, comfort, and even your mood. One of the most surprisingly impactful additions to my setup came in the form of a BenQ ScreenBar a couple of years ago. At first, I wasn’t convinced that a light bar could make that much of a difference. But after two years of daily use, I found it hard to imagine my desk without it.

With the explosion of video content across platforms, the demand for efficient video codecs has grown exponentially. AV1 and H.264 stand out as two of the most widely discussed codecs in the industry today, each with its unique strengths, limitations, and ideal use cases. Understanding their differences and when each codec shines is critical for content creators, platform developers, and even end-users who want the best viewing experience.

Internet-based communication has become the backbone of business operations, personal interactions, and emergency services. Technologies like Voice over Internet Protocol (VoIP) and Web Real-Time Communication (WebRTC) have revolutionized communication, offering flexible and cost-effective alternatives to traditional telephony. However, regulatory challenges in some countries pose strict restrictions on VoIP services.

You are building the next best thing. You are scoping out some amazing features. But now you have to add a way for someone running your software to configure things. So, you break out the JSON parser and start coding the interpretation of your new-fangled config file format.

Apple tends to bring improvements to the UI on each major platform release. One of these nice improvements is the new Action Menu List. The Action Menu List is a nicely animated menu, typically under a button at the bottom left of an app’s message entry screen. When building for iOS 17 and beyond, you’ll want to build a UI that takes the best of what Apple shows us.

Most software developers are familiar with tools to lint their source code. Linting code is the process of checking your code against a defined set of rules to help keep a consistent naming convention, prevent common mistakes, and anti-patterns in other aspects of your code, provided the requirement can be expressed in configuration understood by your linting tool.

To give myself some perspective, I tend to list a few of the things I did in 2022. If I don't write what I did on a regular basis, I tend to get the idea I cruise along career-wise, which makes me increase my efforts to a rate I can not sustain. The funny thing is, in hindsight, I always see and think I did get many things done.

Of course, you can isolate things by running a tool like NVM, RBEnv, or PyEnv. But there is still a risk of doing something to your system that will break things, causing you to spend loads of time fixing your setup for your current main project.

Do iOS is a conference in Amsterdam. It is the 4th edition. Previous editions were organized in 2015, 2016, and 2018. The event itself has quite an interesting history. The best part is I have been involved with each edition.

I've read a tweet the other day with someone asking whether or not doing no coding at all besides your dayjob is a problem or not. This person was clearly someone not doing much coding besides his own dayjob and was curious to learn if that's ok or not.

On August 11, 2021 I took delivery of a KeyboardIO Atreus keyboard. And I have been using the Atreus for over 10 months now and I just love this keyboard. Sometimes I still need to look keys on the reference card. But I am mostly able to just write and program with it and my typing speed is on the same level as it was on a regular keyboard.
