Falling back to patching base and 3-way merge...

It’s not that special

.xcodeproj

It’s a folder

Two kinds of files

Plist and XML

All the settings

Schemes, too

project.xcworkspace

another “special” folder

contents.xcworkspacedata

references .xcodeproj

<?xml version="1.0" encoding="UTF-8"?>
<Workspace
version = "1.0">
<FileRef
location = "self:MyApp.xcodeproj">
</FileRef>
</Workspace>

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 UID

objects = {
532ABB3011D5647300D29D20 = {...};
532ABB3111D5647300D29D20 = {...};
532ABB3211D5647300D29D20 = {...};
532ABB3311D5647300D29D20 = {...};

Don’t .gitignore

The Big Picture

.pbxproj: It’s just a plist

.xcworkspace: It’s XML

xcshareddata: Has plists

xcuserdata: Has plists

Merge Conﬂicts

1. Check the comments

2. Pick 1 UID

3. Rebase early and often
