How to Get the Console Logs from the iOS Simulator

How can I get the console logs from the iOS Simulator?

iOS Simulator > Menu Bar > Debug > Open System Log

---

Old ways:

iOS Simulator prints its logs directly to stdout, so you can see the logs mixed up with system logs.

Open the Terminal and type: tail -f /var/log/system.log

Then run the simulator.

EDIT:

This stopped working on Mavericks/Xcode 5. Now you can access the simulator logs in its own folder: ~/Library/Logs/iOS Simulator//system.log

You can either use the Console.app to see this, or just do a tail (iOS 7.0.3 64 bits for example):

tail -f ~/Library/Logs/iOS\ Simulator/7.0.3-64/system.log

EDIT 2:

They are now located in ~/Library/Logs/CoreSimulator//system.log

tail -f ~/Library/Logs/CoreSimulator//system.log

Viewing Console.log in ios simulator

You can watch the console.log with a safari-browser. Open the ios-simulator or connect the ipad by usb. Open safari and take a look in the menu "developer". Choose your web-site and the web-inspector will open.

How to see logs when running app in iOS simulator directly?

Depending on the runtime version, you can use one of:

xcrun simctl spawn booted syslog -w
xcrun simctl spawn booted log stream
tail -F "$(xcrun simctl getenv booted SIMULATOR_LOG_ROOT)/system.log"

If you're on macOS Sierra, you can also select the simulated device from within Console.app to see the logs.
