iPhone Dev - How important is Project.pbxproj?
The project.pbxproj contains all of the metadata about your project that Xcode uses to build it; the settings, the file references, configuration, targeted platforms, etc...
I.e. it is a critically important.
There really isn't a great answer for this. Typically, teams will avoid conflict by limiting edits to the project to one team member at a time.
The Xcode team has put a lot of effort into making the file merge-friendly. In managing several large projects via svn, I've generally found that the merges are automatic and painless.
Until they aren't. And when they aren't, revert, merge changes by hand (i.e. make the changes in the project that conflicted), and move on.
Try my script xUnique.What it does:
- convert
project.pbxproj
to JSON format - Iterate all
objects
in JSON and give every UUID an absolute path, and create a new UUID using MD5 hex digest of the path- All elements in this json object is actually connected as a tree
- We give a path attribute to every node of the tree using its unique attribute; this path is the absolute path to the root node,
- Apply MD5 hex digest to the path for the node
- Replace all old UUIDs with the MD5 hex digest and also remove unused UUIDs that are not in the current node tree and UUIDs in wrong format
- Sort the project file inlcuding
children
,files
,PBXFileReference
andPBXBuildFile
list and remove all duplicated entries in these lists- see
sort_pbxproj
method in xUnique.py if you want to know the implementation; - It's ported from my modified
sort-Xcode-project-file
, with some differences in orderingPBXFileReference
andPBXBuildFile
- see
- With different options, you can use xUnique with more flexibility
