Better 'printf' Debugging

A couple of useful tricks for debugging with print statements

Get Started With Allocation Profiling

Investigating memory leaks is not a typical use case for allocation profiling. Still, combined with other tools, the profiler can point us in the right direction

Debug Unresponsive Apps

Debugging UI freezes is easier when you use the right tools and techniques. Let's consider a couple of them using a hands-on example
