A few years ago Apple introduced TouchID on the iPhone5S. Instead of asking your user for a password, you can just ask for their fingerprint (if their device has TouchID) which improves the UX by a gazillion times.
With the introduction of iOS7, it was impossible for a developer to use the fingerprint sensor for authentication. Luckily in iOS8, Apple provided us with an API to do so.
In this tutorial I’ll show you how you can integrate TouchID authentication in your application.
With the introduction of the iPhone 6S (plus), Apple added a pressure-sensitive layer to their screen. This creates a bunch of new UX possibilities for creating apps. It’s possible to do a hard press on an application icon and get shortcuts which take you to a specific point in your app. For example, if you do a hard-press on the Photo’s app icon you can quickly search for an image, check the most recent images or see your favourites. It’s also possible to make these quick actions dynamic, meaning that you can add and remove actions based on the state of your application.
In this tutorial I will show you how you can add these quick actions to your application icon.
At the 2014 WWDC conference Apple announced Swift as a new language to write iOS app. In February 2015 they released Swift 1.2, which fixed a lot of issues (especially with the compiler) and added new language features.
In June 2015 Apple announced at WWDC Swift 2, which will be made open source later this year. In this post I will cover the new features in Swift 2.
Update: I’ve created a new tutorial for Xcode 7 & Unity 5.
Last year I published a blog post about how to integrate Unity3D within a native iOS application.
Last week I found a better way to integrate Unity3D within a native iOS app, which also eliminates some issues with my previous version. Because it’s quite a long explanation to do and I noticed in my previous blog post that not everything was crystal clear, I’ve made a video tutorial how you can achieve this.

Last year I published TNCheckboxGroup for Objective-C, but I had a few comments it didn’t work when using with Swift. So I just published a Swift version on Github. This versions leverages UICollectionView to handle big sets of checkboxes. TNSwiftyCheckboxGroup, create checkbox groups in Swift.

Yesterday I stumbled upon a problem when I loaded a xib file within my development pod.
I checked StackOverflow and found a few threads with the same issue:

For a project I needed to add a UIPickerView with custom cells using AutoLayout. UIKit allows this via the UIPickerViewDelegate method pickerView(_:viewForRow:forComponent:reusingView).
The cell just needed an UIImageView and UILabel, so I thought it would be pretty straightforward to do, but there are some caveats you need to know. Big thanks to Tom Adriaenssen for pointing them out and not ruining my Sunday afternoon 🙂

Too many times a client has asked to add a sliding image gallery to an iOS app, so I wrapped it up in a little component. You can download it from GitHub.
I took some time to write this component, so it is easy to manage image slider galleries. First I looked around on the web, but there was nothing that really fitted my needs, so the best thing to do in such a case is write it yourself :-).
You can download the project on GitHub. If you have any questions, just ask it on Twitter, put a comment below or open an issue on GitHub.
The component is also available via CocoaPods.
@thenerd_be je kan het heisa noemen of gewoon vaststellen dat iPhone-only apps uitbrengen op meer en meer gemor onthaald wordt. Terecht.

En toen brak er nog eens een goede oude Twitter discussie uit.
For a few projects I have to use Mapbox’s Tilemill so I can generate mbtile files. I just booted my Tilemill application for the first time on Yosemite, but it gets stuck and I get a never-ending preloader thingie. It seems that the app broke with the update to OSX Yosemite 10.10.
Luckily the solution ain’t that hard. Just build it yourself!
