New features in Swift 2

Swift 2

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.

A better way to integrate Unity3D within a native iOS app

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.

Custom cells for UIPickerView with AutoLayout

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 🙂

TNImageSliderViewController – an image slider gallery for Swift

The problem

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 :-).

Prerequisites

  • Xcode
  • iOS8+

Features

  • 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)

Download

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.
