Is there any way to view iOS device logs on the Terminal?
i believe libimobiledevice is what you're looking for. github repo can be found here

it's a cross-platform lib talking to iDevices with no jailbrake needed. just use console command


  $ idevicesyslog


you can install it via homebrew or compile from sources

macOS install via homebrew


  $ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
  
  $ brew install -v --devel --fresh automake autoconf libtool wget libimobiledevice
  
  $ brew install -v --HEAD --fresh --build-from-source ideviceinstaller


linux


  sudo apt-get update
  
  sudo apt-get install libimobiledevice ideviceinstaller
