Here’s my own list of the interesting stuff announced during this year’s WWDC, collected from the keynotes, various Apple docs, blog posts and tweets.
If you’re planning to watch the videos, I really recommend this Mac app that helps you download and watch them: https://wwdc.io.

If you build iOS apps, you’re used to providing all icons and other images in @1x and @2x versions for older and Retina screens respectively (or rather @2x and @3x now). And it’s pretty easy to test if all those versions work or not, by starting the right iOS simulator and looking at it scaled to 100%.
If you work on Mac apps, you should also include @2x images for Retina Macs now; but if you’re like me, you might have treated that so far as something not urgent that can be done later…
When you do get around to that, if you don’t have any Retina Mac yet, you’ll quickly notice a problem: how do you test your app on a Retina screen? There’s no OSX simulator in Xcode, after all.
In iOS 8 Apple made some changes to how apps are supposed to request access to location data. If you use CLLocationManager and you don’t make any changes for iOS 8 compatibility, your app might stop receiving location data at all.
The biggest change is that apps can now ask to get location data either “Always” or “While Using”:
Mac applications often add their icons to the notification area on the right side of the menu bar. That way they can show you some status changes by changing the icon image, and they can also save some space in your dock by removing the icon from there while still being easily accessible.
If you’re like me, you probably have quite a lot of those there:
The menu bar controls usually display their standard (preferably dark) icon on a standard background by default, and an inverted white icon on a blue background when clicked:
This is my SSL configuration guide. There are many like it, but this one is mine…
Last week I needed to set up my first HTTPS site for Hive Mac [link removed – site has been shut down since then], and I went ahead and did the same thing for my new blog domain. It took some figuring out, so I’ve written this all down, if only to save myself some time next time I need to do this.
Update 22.01.2019: I’ve now switched to Let’s Encrypt which makes the whole process much simpler. See “Setting up Let’s Encrypt”, and then jump to “Testing the certificate” when you’re ready.
This is the first part of a new (hopefully) longer series of tutorial-like posts. I’m planning to write shorter posts now but more often, based on specific things that I learn while working on my current projects. Let’s see how long I manage to keep this going… :)
Let’s say you have an iOS app that was build for iPhone 5S and earlier. Now that the new iPhones are out, you want to make it work on them too.
If you don’t change anything and just build your app with the latest Xcode and iOS SDK, you’ll see that the app runs on the new iPhones scaled up: the views are rendered on a standard iPhone 5S sized screen and then resized to a bigger resolution like you would resize a static image, together with the top/bottom bars and everything (which obviously doesn’t look good).
To make the app render on the new iPhones natively, you need to let iOS know that it supports them. There are two ways to do that:
I don’t know about you, but I never know which NSButton to pick from the Interface Builder library panel. When you start looking for a button there, this is what you see:
13 different buttons, all described with the same meaningless description:
The NSButton class is a subclass of NSControl that intercepts mouse-down events and sends an action message to a target object when it’s clicked or pressed.
Each of them looks slightly different, but which of these are you supposed to use in what context?
I’ve read a post comparing Backbone to AngularJS recently, and another that ended with similar conclusions about Backbone, and since I’ve been working with Backbone for the last year or so, I thought it would be a good idea to share my own experiences with it.
In 2012 I’ve been working with a few other developers at Lunar Logic on a new webapp. We’ve decided from the beginning to build it as a single page application, based on an API that was being developed for an existing mobile app. We have considered EmberJS for a moment, but we’ve decided it probably wasn’t stable enough at that point, so we went with Backbone instead.
Looking back I think we made the right choice back then – EmberJS has changed a lot since then (some important parts were still being changed a couple of months ago in 1.0-pre versions), and they still haven’t released a final 1.0, though it seems it’s getting close to that. I’m also glad I had a chance to learn Backbone and get to see its pros and cons. Still, if I was starting the same project right now, I’d probably choose Ember instead.
So what have I learned about Backbone during this year?
