I have a Set File Icon error frequently these days. The message:
[[NSWorkspace sharedWorkspace] setIcon: myImage forFile: [[sheet URL] path] options: NSExcludeQuickDrawElementsIconCreationOption];
Appname[xxx] [default] Invalid image size X: 1024 Y: 1152
My new XCode update sets the file icon as it should but displays the message 14 times. In older versions of Zcode, it never occurred to me.
