I use Xcode and LLDB to debug my Qt programs, and got tired with there being no visualisation for all the built-in types. Here I endeavour to make all of these types visible through the debugger. Works with Qt 5.5.
hg clone this repo somewhere, e.g. ~/qtlldb. Then add the following lines to your ~/.lldbinit:
command script import ~/qtlldb/QtFormatters.py
command source ~/qtlldb/QtFormatters.lldb
