If you’re tired of seeing MyCompanyName automatically in all copyright notices of all your XCode source files then here’s a quick and easy fix. You can set the XCode default company name for copyright notice as follows:

Go to /Applications/Utilities and open Terminal.app and enter the following code:

defaults write com.apple.Xcode PBXCustomTemplateMacroDefinitions '{"ORGANIZATIONNAME"="SomeOther Co.";}'

Make sure you replace SomeOtherCo. with whatever name you want. I used:

defaults write com.apple.Xcode PBXCustomTemplateMacroDefinitions '{"ORGANIZATIONNAME"="damagestudios.net";}'
