I was using the Prisma app (like half of the world probably) and noticed the info bubble when you swipe with your fingers to adjust the strength of the effect.
This is my implementation (written in Swift) of this component, which comes with the Prisma look out of the box.

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.

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.

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.
Introducing an image slider gallery for Swift
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 :-).
- Horizontal scrolling
- Vertical scrolling
- Page control to indicate how many photos are in the list
- Works in both orientations (landscape, portrait)
- Cell reuse (works on UICollectionVIew)
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.
