Hello,
Although this is my first time on this website, I have been a blogger for over 6 years now, and an Apple developer for over 3 years. I know my way around Objective-C quite well, and I've caught up with Swift pretty fast. I've read Apple's book series: Introduction to Swift Programming Language, and since I am a registered Apple iOS developer, I have tested Swift on my own in my computer for future work.
Regarding my writing skills, I've been writing for my blog and collaborating in some others for quite some time. Since I'm studying in college, I've been needing to write lots of essays and articles for academic purposes, so I learnt to write in a clean and structured way, without grammar or spelling mistakes.
Thank you for considering my big, let me know if you want any sample articles I've written.
