Two options  libimobiledevice is installable via homebrew and works great  Its idevicesyslog tool works similarly to deviceconsole  below   and it supports wirelessly viewing your device s syslog     I ve written more about that on Tumblr tl dr  brew install libimobiledevice idevice id --list    list available device UDIDs idevicesyslog -u  lt device udid gt   with the device connected via USB or available on the local wireless network    Keeping for the historical record  from 2013   deviceconsole from rpetrich is a much less wacked-out solution than ideviceconsole above  My fork of it builds and runs in Xcode 5 out of the box  and the Build action will install the binary to  usr local bin for ease of use  As an additional helpful bit of info  I use it in the following style which makes it easy to find the device I want in my shell history and removes unnecessary  gt  lines that deviceconsole prints out  deviceconsole -d -u  lt device UDID gt    uniq -u  amp  amp  echo  quot  lt device name gt  quot

EDIT  Please use  cbowns solution - deviceconsole is compatible with iOS9 and much easier to use   This is a open-source program that displays the iDevice s system log in Terminal  in a manner similar to tail -F   No jailbreak is required  and the output is fully grep able so you can filter to see output from your program only   What s particularly good about this solution is you can view the log whether or not the app was launched in debug mode from XCode   Here s how   Grab the libimobiledevice binary for Mac OS X from my github account at https   github com benvium libimobiledevice-macosx zipball master  Follow the install instructions here  https   github com benvium libimobiledevice-macosx blob master README md  Connect your device  open up Terminal app and type   idevicesyslog   Up pops a real-time display of the device s system log   With it being a console app  you can filter the log using unix commands  such as grep  For instance  see all log messages from a particular app   idevicesyslog   grep myappname   Taken from my blog at http   pervasivecode blogspot co uk 2012 06 view-log-output-of-any-app-on-iphone-or html

You have three options    Xcode Organizer Jailbroken device with syslogd   openSSH Use dup2 to redirect all STDERR and STDOUT to a file and then  tail -f  that file  this last one is more a simulator thing  since you are stuck with the same problem of tailing a file on the device     So  to get the 2   one you just need to install syslogd and OpenSSH from Cydia  restart required after to get syslogd going  now just open a ssh session to your device  via terminal or putty on windows   and type  tail -f  var log syslog   And there you go  wireless real time system log   If you would like to try the 3   just search for  dup2  online  it s a system call

Try the freeware iOS Console   Just download  launch  connect your device -- et voila

As an alternative  you can use an on-screen logging tool like ticker-log to view logs without having  convenient  access to the console
