From time to time I will also put various bits of iOS programming code on the blog. I’m a writer, and a writer of code as well. I find it easy to keep useful code in one place. My own Blog. Currently, I’m working on a Chatbot App based on Googles Dialogflow API. I have a couple of nice little apps on the Apple App Store already. It’s an interesting way to avoid writing my books!
