Tell the Source of a Print Output in Xcode

Question

I'm getting 0.0 printed repeatedly in my debug output area. It prints it maybe about every 0.5 seconds or so. I've been trying to find where this is coming from for quite some time and I cannot seem to find it. Is there any way to see where in my code this is being printed? Here's an image of what is happening:

One possible way to find this is to set a symbolic breakpoint on the symbol print and then run your app. When any code in your app attempts to call print, the debugger will stop within the assembly code from the print function. Look at the stack trace in the debugger to see what is calling print. Then click the "step out" button in the debugger to finish that call to print and see if 0.0 appears in the console. If it does then that print is probably your issue.

It's possible the output is not using print. It could be NSLog or OSLog.

Thanks a bunch! It ended up being that I had a timer in the background that I accidentally had started whenever the view loads and I must have been printing to test something and I just neglect to remove it. But thanks for the help because without you telling me how to do that, I would've probably never have found that!
