What is the stuff between the [] in the log message below? I get this in my iPhone app, and I have no idea where the message is coming from. My first guess would be a line number, but which file would it be in?

The square brackets indicate that these arguments are optional. You can leave them out. So, in this case you are only required to pass the csvfile argument to csv.DictReader. If you would pass a second parameter, it would be interpreted as the fieldnames arguments.
Usually in api documentation square brackets mean optional. I would think they mean the same here. Show activity on this post. This is actually a subset of the widely used notation to unambiguously describe language syntax called Backus-Naur Form (see Wikipedia article for details). Show activity on this post.
Citation styles with numbers in brackets. 1 #1 Vancouver. The Vancouver style is a numeric citation system used in biomedical, health and other science publications. This style consists of ... 2 #2 IEEE. 3 #3 ACM. 4 #4 Physical Review Letters. 5 #5 Elsevier. More items
Some of the most notorious journals that use citation styles with numbers in brackets are: Elsevier, Physical Review Letters, and PubMed. ✍️ Do I have to create a reference list with numbers in brackets manually? You can, but you don't have to.
The first number is the process ID, the second is the logging thread's Mach port. A desktop example:
2010-10-19 17:37:13.189 nc_init[28617:a0f] nc <CFNotificationCenter 0x10010d170 [0x7fff70d96f20]> - default <CFNotificationCenter 0x10010d2a0 [0x7fff70d96f20]>
(gdb) i thread
Thread 1 has current state "WAITING"
Mach port #0xa0f (gdb port #0x4203)
frame 0: main () at nc_init.m:10
pthread ID: 0x7fff70ebfc20
system-wide unique thread id: 0x167b49
dispatch queue name: "com.apple.main-thread"
dispatch queue flags: 0x0
total user time: 13232000
total system time: 16099000
scaled cpu usage percentage: 0
scheduling policy in effect: 0x1
run state: 0x3 (WAITING)
flags: 0x0
number of seconds that thread has slept: 0
current priority: 31

suspend count: 0.
(gdb) p/x (int)mach_thread_self()
$1 = 0xa0f
Notice how 0xa0f is reported as the thread's Mach port.

first number is the process ID, unsure about second, this line will precede every line thats printed to console from your application.
Possibly a NSLog(@""); is causing this.
Is your application running or has it crashed by this stage?
