How to read iPhone system logs?

Solution 1:

This can only be done on a mac:

• Connect your device to a Mac

• Open Xcode, go to Window->Devices in the title bar

• Click on your device from the sidebar

• Click 'View Device Logs'

You don't need to be enrolled in a developer program to be able to do this. To this on windows you'll probably need some sort of virtual machine/hackintosh

Solution 2:

As Samantha said, it can only be done on a mac.

Apple Configurator 2 is a free macOS app published by Apple. Among other features, it allows access to the device logs.

1. Download and install Apple Configurator 2 on a Mac (~65 MB free disk space required)
2. Connect the iOS device to the Mac and trust the computer
3. Start the Apple Configurator 2
4. Within the "All Devices" view double-click on the device attached to the Mac. An overview of the device is shown
5. On the left hand menu bar click on "Console". The console of the device opens showing a live log

Solution 3:

You can view the logs of an attached iDevice, without installing any extra software on a Mac, by just using the Console app (usually found in Applications/Utilities folder). When you run the Console app the attached device will show up under the Devices in the left panel of the app. If you click on the device you can see and search its log.
