Hey there, welcome to Always Processing, a place where we explore many aspects of software development in detail. To browse the blog content, head over to the All Posts page, where you'll find links to everything I've written so far.
Currently, the site focuses on Objective-C and iOS, but I plan to cover more topics soon, like Swift, Rust, C++, macOS, Xcode, and Visual Studio Code. Also, expect to hear some fun anecdotes as I recall experiences from my career in software development.
But this isn't just about code—it's about the passion for exploring the ins and outs of how things work. From debugging to discovering new tricks, I'm excited to share my experiences with you. And as a work in progress, I'm always open to your feedback and ideas for future posts. So be sure to check out my contact information on the About page and drop me a line.
Thanks for stopping by, and happy coding!
