I have been a developer for over 30 years and have been a mobile developer for over 10 of those years. During that time, I've developed over 90 iOS apps, around 10 macOS apps, and quite a few Android apps too - some were personal apps while close to half of that were apps for various clients.
I’ve also been a technical editor, final pass editor, and finally, for a brief period, the editor-in-chief at raywenderlich.com, the popular online site devoted to mobile and game development. I did a lot of work on their tutorials and so know a little bit about helping people to understand a topic :)
I try to help people understand developing for a given language and try to show you why you should do something a certain way. Along the way, I also try to provide little tips and tricks which make your work in a particular development environment (like Xcode) much easier. And I have no problems at all with questions - the more questions you have, the more you'll learn and I'll answer any (and every) question you may have!
I also tend to be very good at debugging code issues - even if the issue is in code written by others. I can dive into somebody else's code and quickly find the root cause of a bug. So, if you are stuck on a bug which has stumped you for several hours, I believe I can help.
