ios app logs are not printing to stdout with ios 9.0

[ChinmayeeVasisht]

I am on ios-sim version 5.0.2 , when i launch an iPad app on iPad 2 (9.0) , i see that logs related to my app is not being redirected to stdout, i only see the simulator logs.

ios-sim launch appname.app --devicetypeid iPad-2 --log /tmp/ipad.log

I see only NSLogs, but the C++ portion of the logs are not printed. It used to work fine with 3.x ios-sim version with iOS Simulator 8.1

With ios-sim version 3.0.0 on Mac 10.10.5 OS , i see this warning -

I've similar issue with c++ gtest logs, I can't get them by using --log option

This is correct, it's only tracking logs printed using NSLog. Currently I don't have a solution to grab the other type of logs, 3.x used a different mechanism that is not used here (this is basically just a grab of the log spit out by the Simulator itself).

You'll probably have to do some redirection yourself of the C/C++ logs through dup2 etc if you have access to the source and have the filehandle: https://www.bignerdranch.com/blog/hijacking-for-fun-and-profit/
