I found an example on the website of Apple developers about the library looking ImageKit in which scanners connected but there is a problem because when I connect my scanner is not detected, I ran the program and tells me there is a function NSBeginAlertSheet deprecated.
Somebody help me solve problems.
The link is here.
NSBeginAlertSheet was deprecated in OS X 10.10 and it is recommended to use NSAlert instead. Source: https://developer.apple.com/library/mac/documentation/Cocoa/Reference/ApplicationKit/Miscellaneous/AppKit_Functions/index.html#//apple_ref/c/func/NSBeginAlertSheet
That specific error is not related to ImageKit.
