Logs in iOS simulator

Option 1: Use GUI log

1. In simulator, press ⌘ + / or go to Debug -> Open System Log.
2. That's it.

Option 2: Open it in terminal

1. Run instruments -s devices
2. Find the device / OS version that the simulator you are using, eg: iPhone 6s (9.2) [5083E2F9-29B4-421C-BDB5-893952F2B780]
3. The part in the brackets at the end is the device code, so you can now do this tail -f ~/Library/Logs/CoreSimulator/DEVICE_CODE/system.log, eg: tail -f ~/Library/Logs/CoreSimulator/5083E2F9-29B4-421C-BDB5-893952F2B780/system.log
