Some time ago I have started Cute Contacts a project for studying how well QML as of Qt 5.3 is fit for prototyping iOS app. By now the project is done enough to see how fit things are. On the way I have found a few bugs, found some generic inconveniences and learned a lot.
I will probably post more on the findings, possibly it could help Qt project folks to save some time when developing Qt Quick controls for iOS. For now, just have a look at the video. For more details watch the project page or subscribe to this blog RSS feed.
And sure feel free to grab the code on Github and study it or do with it whatever you like.
