Qt 5.6.0 released
I've used Qt many years ago (2007) and I liked the experience, but I had to move away from it because our company decided to go native on all fronts..For internal tools/prototypes I was using JUCE for my UI needs, which is much smaller in scale that Qt, but it produced very slim executables, was fast and good enough for my needs (plus I loved the API). I still think this a great framework for small UIs and tools, especially if you're working with sound.Then I took a two years break from C++, moving to full time Objective-C, then Swift 1 and 2, working with and actually enjoying the power of UIKit.. I've developed several UI-heavy apps for iOS and some OSX stuff.This year I came back to C++ and coincidentally, Qt.What a nice come back this is. I'm thoroughly enjoying Qt (I'm currently using 5.4). 
The development is smooth and intuitive, I don't have to spend hours reading documentation and articles, it kind of just flows by itself (not so at all with UIKit )After trying out many frameworks and kits, If I had to pronounce a verdict for the best cross platform UI framework - then Qt has no competition, both in terms of features and in terms of pleasure.I hope I can say the same about 5.6, will definitely try it out.Edit: let me know if you need a Qt dev, as my current project is closing to an end and I would love to continue using Qt .
