WWDC 2015: Auto Layout improvements

June 22nd, 2015 by

Last weekend I arrived home safe and sound, already missing San Francisco. I had a wonderful time there and I have lots to talk about, but there was one topic in particular I think was not highlighted enough. That’s why I want to discuss it here. It was discussed in the following talks during WWDC:

Mysteries of Auto Layout – part 1
Mysteries of Auto Layout – part 2

I am a big fan of auto layout since it was introduced in iOS 6 and especially by using it directly in code, not by using Storyboard. But when using it in code it can get really verbose. I wrote some classes around that to make the resulting code much more compact. I wasn’t happy with my solution. So I was planning to go to a Lab during WWDC, to ask an actual Apple auto-layout engineer for his opinion about this matter. But it turned out I didn’t have to! Apple solved most of the problems I was having with Auto Layout with new API’s in iOS 9! In this blog I want to highlight those new API’s which make it easier to work with Auto Layout both in code and in Storyboard!

WWDC Day 1 continued

June 11th, 2015 by

Hello again from San Francisco! I just came back from the conference after attending it for the third day in a row! I have seen many interesting talks so far ranging from Swift to WatchKit and UI design. There is so much to talk about, but in my previous blog entry I could only cover the keynote of the first day. Otherwise it would have been way longer! So let’s continue where I left off …

WWDC Day 1

June 10th, 2015 by


Greetings from my hotel room in San Francisco, from where I’m writing this blog post. Right now it’s Tuesday evening and it has been two exciting days at the WWDC which takes place this week from Monday the 8th until Friday the 12th of June as I had announced earlier. Although I have three more days to go, I already wanted to give you guys an update on how everything has been going so far.

I have so much to talk about so I am trying to be brief, but I can already tell this isn’t going to be a short blog post. So get a cup of coffee, get a comfortable chair, sit back and relax. Are you ready? Here goes …

iOS Development Tips & Tricks – Part I

December 19th, 2013 by

As you might know, I am very fond of developing apps for the iOS platform. I started back in mid-2009 by trying to create an app for the Dutch Lowlands festival but I unfortunately failed to make the app a reality. I didn’t care because now I learned how to write iPhone apps!

After that I never stopped trying out new app ideas in my spare time and occasionally blogging about it. In 2010, I created an app to use to communicate with friends using our custom forum-like website which was called ‘Yert’.

EasyCalendarAnd later, March 2011, I created an app in my spare time together with my uncle (Jos Jong) and brother (Jim van Zummeren) which turned out to be quite profitable: Easy Calendar. I learned the most creating this app. I also developed some iOS apps for clients of Trifork, for example I made the love to load app for The New Motion and an app that allows doctors to log their hours for GeriMedica: Ysis Mobiel.

Oh, and I almost forgot: Learn to write with Tracy! An iPad app that makes learning how to write for children more fun and thus effective.Tracy

Next to the apps that made it into the App Store, I worked on a bunch of other ideas in my spare time that unfortunately never saw the light of day. But I learned from them every time. I want to share some tips & tricks with you all, which I learned over time. I want to talk about what tools I use nowadays, what frameworks I recommend and the different ways of distributing an app.

Apportable (a much better alternative to Phonegap) and AFNetworking 2.0

October 22nd, 2013 by

cocoahead_sm2On October 16th I attended CocoaHeads, an iOS developer meetup that is organized every few months by Peter Robinett of Bubble Foundry and other volunteers. Every time it’s hosted at a different location. It was previously hosted at Spil Games, Xebia and NOS. This time it was hosted at eBuddy. The formula is simple: great speakers show up and talk about interesting frameworks, hacks, tricks and so on. During the presentations, attendees can enjoy some free drinks and food.

This was the fourth time I went and it was the best edition yet! That’s why I decided to blog about it this time. I believe this was the best edition because there were talks given by two speakers from San Fransisco: Matt Thompson and Zac Bowling and they talked about some pretty interesting and even mind blowing topics.

Windows Phone 8 – C# vs. Java

September 17th, 2013 by

Welcome back to another brand new Windows Phone 8 blog! After I explored the UI and checked out the IDE it is now time to take a look at the programming language: C# or “C sharp”. I want to focus purely on the language itself and compare it to the language I know best: Java. I was surprised how good C# was compared to Java. The syntax of both languages look a lot alike. I want to highlight some of the language features I discovered while writing my first app of which I thought: wow, I wish Java would have this!

Developing Windows Phone 8 apps

In this blog I want to dive a little bit into developing apps for Windows Phone 8. I want to tell you something about the programming language you will have to use, the IDE and anything else you need to know to start developing your own Windows Phone app. I will also talk about ReSharper, which made my life so much easier!
