I want to check device id for my iPhone simulator application. But not using codebase. I know the way how to do with codebase, using UIDevice instance.
Is there any way to find device id without using codebase?
Is the iPhone Simulator UDID unique for each installed instance?
This answer should be what you want. Look at System Profiler on your mac and the id is there. I just tested on my machine and the IDs match.
This is the exact Terminal command you can enter to view it:
system_profiler SPHardwareDataType
Try this
instruments -s devices
As so often, there is a Xcode terminal tool for that (part of the Xcode tools) see xcrun manpage
xcrun simctl list | egrep '(Booted)'
lists only all booted (could be more than one) Simulators
(remove | egrep '(Booted)' to see them all).
UIID results like
iPhone 6 Plus (AAAABD40-9DE6-44B7-A4EA-B34ABCDEFCA6) (Booted)
you can then lookup a folder in ~/Library/Developer/CoreSimulator/Deviceson your Mac and find all the "belongings" of that particular Simulator
Xcode -> Window -> Devices and Simulators -> Select Device for which you want identifier (Inside details you can see identifier)
You can also retrieve the same UDID, labeled as "Identifier," in the Xcode Organizer by selecting "My Mac" from the list under Devices.
You can visually review the value in the simulator by navigating to home/Settings/General/About/Serial Number which is the same as your desktop machine. You can verify this by navigating to Apple/About This Mac and clicking the OS version number under OS X (the display will change to indicate your UDID - you may need to click it twice).
There is another way without using command line, inside this plist file ~/Library/Developer/CoreSimulator/Devices/device_set.plist, it lists down all the devices with UUID.
