It’s not that special


.xcodeproj


It’s a folder


project.xcworkspace


another “special” folder


contents.xcworkspacedata


references .xcodeproj


xcuserdata


Not just in .xcodeproj


project.pbxproj


it’s a plist


a very special plist


the heart of your project


let’s look inside

Let’s break it down


‘objects’ and ‘root_object’


‘objects’


objects = {D94D3E72170B80FB00EA401C = {...};D94D3E74170B80FB00EA401C = {...};D94D3E76170B80FB00EA401C = {...};532ABB3011D5647300D29D20 = {...};532ABB3111D5647300D29D20 = {...};532ABB3211D5647300D29D20 = {...};532ABB3311D5647300D29D20 = {...};};


Every object has a UUID


objects = {D94D3E72170B80FB00EA401C = {...};D94D3E74170B80FB00EA401C = {...};D94D3E76170B80FB00EA401C = {...};532ABB3011D5647300D29D20 = {...};532ABB3111D5647300D29D20 = {...};532ABB3211D5647300D29D20 = {...};532ABB3311D5647300D29D20 = {...};};


‘root_object’


isa = PBXProject;


mainGroup = A487DC7415FE5DCD0037E8A3;


targets = (! 1D6058900D05DD3D006BFB54 /* MyApp */,! D94C698916E6E808002BDD31 /* MyApp Test */,! D9E1D32A16E6FCC100C0524D /* MyApp Pro */,);

The Big Picture


It’s just a plist


How does this make our lives suck less?


project.pbxproj -text


Make it readable


Make it JSON


Xcode don’t care
