I want to replace some placeholders in my .pbxproj file with real data before the compilation occurs. In a plain text of .pbxproj I have entries like REPLACE_ME_BUNDLE_ID or REPLACE_ME_TEAM_ID in place of app's bundle identifier and Development team respectively.
May I use a Run-script phase for that?
Or is Xcode known for saving the .pbxproj in some safe place before the build and use it from there?
UPD: I do not use any xcconfig files, nor these placeholder values are declared anywhere. The question specifically is whether Xcode copies and hides the .pbxproj before the build starts and uses that copy, or am I allowed to modify the .pbxproj during the build?
These values will be replaced by the actual values before compilation.
Compilation will not succeed if these values are used as-is.
The values will be picked up based on the project 'Configuration' currently set as-per the build scheme (or as-specified in the build command if that is how the build has been initiated). You may locate actual values of these placeholders under build settings of your xcode target, and in-some cases they might come from the environment.
If this helps, kindly consider marking this as the answer, or else please comment and let me know further detail about what you're trying to do, so that I may give it more thought and try to to help you.
