When you create a new project in Xcode the generated files all include a bit of copyright information for you. There are two places Xcode looks to gather the company information used: your address book entry, and the Xcode plist. If a company name is found in your address card entry that name is used. If no name is present, Xcode creates a new dict entry in the plist and fills it with “My Company Name” for you. If both entries are present the plist entry wins.
To see what may (or may not) be in your plist run this defaults read command:
defaults read com.apple.Xcode PBXCustomTemplateMacroDefinitions -dict ORGANIZATIONNAMEIf there isn’t an entry for ORGANIZATIONNAME you’ll get an error, otherwise you’ll see the current value.
To set ORGANIZATIONNAME to a different value run this defaults write command:
defaults write com.apple.Xcode PBXCustomTemplateMacroDefinitions -dict ORGANIZATIONNAME "your value here"Rerunning the read command now should show you the new value for ORGANIZATIONNAME.
