Simple ruby script to check if a Xcode *.pbxproj file structure matches a project physical directory structure. It can be added as a build phase to warn you when your project structure loses its alignment.
History of some (if not any) Xcode developer :) You see some TestClass files in Subfolder group:
But you see something strange in file inspector! The TestClass.[h|m] files are not really located in Subfolder group :o
Using Finder you reveal horrible truth - *.pbxproj file and file system are misaligned!
pbxproj_structure_check can be integrated into your project using CocoaPods. Add following entry to your Podfile:
pod 'pbxproj_structure_check', '~> 1.0.1'
Then add a 'Run Script' build phase to your app target (see Add to Xcode as Build Phase for details). Type following as build phase script:
ruby Pods/pbxproj_structure_check/pbxproj_structure_check.rb ${PROJECT_NAME}.xcodeproj/project.pbxproj
If you get an error from the script about some objects during build, you can ignore those errors by adding object ids joined by ':' at the end of script invocation.
For example: When you get errors about objects D497DE90182D2EFC00924692 and A497DE90182D2EFC00924692 and you would like to ignore those errors, use following invocation:
ruby Pods/pbxproj_structure_check/pbxproj_structure_check.rb ${PROJECT_NAME}.xcodeproj/project.pbxproj D497DE90182D2EFC00924692:A497DE90182D2EFC00924692
$ ruby pbxproj_structure_check.rb
ruby pbxproj_structure_check.rb pbx_path [ignored_id:...]
$ ruby pbxproj_structure_check.rb /allignedProjectPath/allignedProject.xcodeproj/project.pbxproj
$ echo $?
0
$ ruby pbxproj_structure_check.rb /otherProject/otherProject.xcodeproj/project.pbxproj
Object 'D497DE90182D2EFC00924692' named 'Supporting Files' at '/otherProject' has no physical path
$ echo $?
1
# I don't care about this object, let's ignore it :P
$ ruby pbxproj_structure_check.rb /otherProject/otherProject.xcodeproj/project.pbxproj D497DE90182D2EFC00924692
$ echo $?
0
Let's integrate pbxproj_structure_check.rb with your project, so it be a defender of your project's alignment :)
First - copy pbxproj_structure_check.rb to your project root folder.
Select your project in Project Navigator, select your app target and choose Build Phases tab.
From menu bar choose Editor, Add Build Phase and Add Run Script Build Phase.
Run Script has been added, move it up, so it be placed below Target Dependencies. Type pbxproj_structure_check.rb invocation as script:
ruby pbxproj_structure_check.rb ${PROJECT_NAME}.xcodeproj/project.pbxproj
Then you can specify ignored ids at the end of above invocation (e.g. ids of 'Frameworks', 'Products', etc.)
If script detects any misaligned object during build - it reports an error.
I would appreciate any suggestions!
