QML is nice, and IMO a much better version of the HTML/CSS/JS web stack. There are also decent debugging tools and it seems to perform well-enough (though you can certainly shoot yourself in the foot).

But a lot of the QtQuick components and the language itself have weird edgecases that are never documented and probably just simply bugs.

Building reusable components in QML isn't easy. A lot of available properties depend on how you instantiate the component, and it's not always possible to specify exactly what properties you expect to be bound (this is where a lot of the edge-cases that I noticed come in). Components seem to be a somewhat leaky abstraction, especially when used as delegates in views.

And the actual IDE integration of QML into QtCreator is just bad. It's frustratingly slow, loses type information of components very easily, doesn't even highlight properly a lot of the times and has no other advanced integration. It's weird. You'd think such a tightly integrated language could have amazing IDE support, but it just doesn't.
