JSON Parsing in Swift 4
Read More »Updated: 3rd September 2017.
- Checked syntax using Xcode 9.0 beta 6.
- Added section on allowing for nulls.
Since JSON has become the de facto standard for data transfers around the internet, there has always been a lot of interest in Swift libraries to parse JSON into Swift classes or structs. Searching for "swift json library" on GitHub discovers
7786 repositories. So why are there so many? And what has Swift 4 done to sherlock them all? -
Posting from my new iPad
Read More »Last week I got a 10.5” iPad Pro. I have had an iPad ever since the original release, but I have to confess to mainly using it for content consumption rather than creation. Since I am usually close to a Mac anyway, there didn’t seem a lot of point. But now that iOS 11 is really addressing the issue of making the iPad a "pro" device, I decided to give it a try.
So here I am, sitting in an armchair with my iPad on my lap, writing this post and working out the details as I go. Any typos are due to the cat trying to compete with the iPad for space on my lap!
iPad
As already mentioned, I have a new iPad Pro. I also have an Apple Pencil which I use for taking notes. I do not have a keyboard, so I am using the on-screen keyboard right now.

JSON Feed for TrozWare
Read More »jsonfeed.org has announced a new format for web site feeds, designed as an alternative to RSS. TrozWare has had an XML RSS feed for years, but I don't think anyone ever uses it (I certainly don't), so today I have replaced it with a JSON feed, which you can access through the button at the top of every page.

Blackmail Marketing
Read More »I use my iPad to play games as a form of relaxation. Nearly all the games I play are puzzle apps with levels that can be played in a few minutes. Nearly all of them are free to install. So how do they make money?
Now I would be the last person you should consult about marketing but it has always seemed to me that the best way to market your product is to convince people that it offers something they want so that they are prepared to pay for it.
This is not the currently favored approach for mobile apps - at least certainly not for games. No, the theory at the moment is to cause so much frustration and annoyance that people give you money to make it stop. Blackmail marketing.
