While building an iOS app in Xcode, how do I set the log to show only what I print()?
I am wasting a huge amount of time sifting through garbage that looks like this

I end up using hacks like print("SEARCHFORME") so I can use the find command and search for messages I need while debugging.

if you want to view logs from just your application then you can make a custom method that keeps saving the log to a file in documents directory & then you can view that log file from your application. There is one good advantage for developers of the app after the app has been released & users are downloading it.
Or #define NSLog (s,...) The console is hidden by default every time Xcode starts up. (I mean, when you start debugging, the debug area shows just the variables.) There's a button on the right hand end of the debugging toolbar to show the console, or you can use View menu -> Debug Area -> Activate Console.
NSString* url = @"someurlstring"; printf ("%s", [url UTF8String]); By using printf with the appropriate parameters, we can display things this way. This is the only way I have found to work on online Objective-C sandbox environments. In Swift with Xcode you can use either print () or NSLog (). print () just outputs your text. Nothing more.

Go to -> 
Edit Scheme -> Run -> Environment Variables -> set Name to - OS_ACTIVITY_MODE and Value to - disable.
