Recently I have went through the process of adding support for the new watch face complication sizes on the Apple Watch Series 7. Previously, I have used PNG images for the various complication image providers, but with these two new device sizes (41mm and 45mm) things would get a bit out of hand – I felt like it’s time to do it better. In the end, I have spent over 4 days working on this – and in this blog post, I will try to share my learnings and propose what I think is the best approach for having pixel-perfect complications on watchOS 8.
As you’re probably aware, today is the day that iOS 11 comes out! Apart from ARKit, CoreML and the like, it brings one huge change: a completely redesigned App Store.
It seems like a forever ago since I released my last open source code, and, 
App extensions were introduced a couple of weeks ago during WWDC 2014 Keynote as a way to extend the reach of your app to some parts of iOS (8), for example by creating a widget that will show up in Notification Center, or a custom sharing action. It’s no doubt a huge opportunity for iOS/Mac developers, so if you have an idea for a widget/extension, I suggest you start working on it as soon as you can.
In today’s programming tutorial, I’ll show you how easy it is to use OpenStreetMap maps in your app instead of default Apple maps. There are many reasons why you might want to do this: for example, the OpenStreetMap project is being built by a huge community of contributors and therefore the maps are really detailed; or, you might just want to give your users the option to use whatever maps they prefer.
