It is great to see memory usage on Xcode while running an iOS app.
What I thought is that:
1. GC knows available heap memory locations and their length.
2. GC can detect what parts of heap is in use.
3. A program can create a file to write (stdout, stderr, etc.)
So, when desired (e.g. use of a compiler flag), on runtime, GC
could write statistical information to a file descriptor every
time it runs. So, anyone could write a program to read that
information to turn it into a graphical chart for profiling
information.
Does GC have any support to collect this type of information
currently?
