In the top menu bar, click Xcode → Settings… → Source Control
There will be Author Name and Author Email here. These two will be displayed in the git commit record, so set them in advance.
There is also an Ignored Files.
It is used to specify which files or folders should not be added to the Git repository. It should come with:
*~
.Ds_Store
But we don’t need to care about it.
Because it is written in .git/info/exclude, it cannot be put into the Git repository.
.git/info/exclude is only local.
So we won’t use it.
But don’t delete the contents.
Because when you create a new project in Xcode, if you select Create Git repository on my Mac, Xcode will automatically commit.
At this time, .git/info/exclude is useful.
After it is built (that is, after the first automatic commit of Xcode is completed).
We can add the .gitignore file, and after configuring the .gitignore file, delete the contents in .git/info/exclude (it doesn’t matter whether it is deleted or not).
Here we take a C++ project as an example:
Open Xcode and click Create New Project… In the Choose a template for your new project: interface that pops up, select macOS, then select Command Line Tool, and click Next to continue.
Product Name can be anything, such as CPP, but please note that only uppercase or lowercase English letters, numbers and - can be used here (you can see the Bundle Identifier: below, and any other characters you fill in will become - ).
Team can be ignored.
For Organization Identifier, just fill in com.local , of course, you can fill in uppercase or lowercase English letters, numbers and - (if it starts with a number, a - will be added at the beginning).
Organization Identifier is used to generate Bundle Identifier, which is just a format requirement. It should not be used when doing C++ command line projects.
Language is unnecessary. We are going to do C++ projects anyway, so just fill in C++.
After filling in these, click Next It will ask you to select a directory, and it will generate your project root directory in the directory you selected.
(Remember to select Create Git repository on my Mac; it is also OK to not select it, and you can manually create the Git repository in the project root directory later).
For example, I will select ~/Documents/Xcode as an example. After selecting it, click Create and it will generate your project root directory in the Xcode directory:
(If the name you wrote in Xcode is abc)
~/Documents/Xcode ❯ tree
.
├── CPP
│ ├── CPP
│ │ └── main.cpp
│ └── CPP.xcodeproj
│ ├── project.pbxproj
│ ├── project.xcworkspace
│ │ ├── contents.xcworkspacedata
│ │ ├── xcshareddata
│ │ │ └── swiftpm
│ │ │ └── configuration
│ │ └── xcuserdata
│ │ └── abc.xcuserdatad
│ │ └── UserInterfaceState.xcuserstate
│ └── xcuserdata
│ └── abc.xcuserdatad
│ └── xcschemes
│ └── xcschememanagement.plist
OK, now your project is created.
If you just selected Create Git repository on my Mac, please create a new .gitignore file.
And write in .gitignore:
.DS_Store
*.log
# Xcode user-specific files
*.xcodeproj/xcuserdata/
*.xcworkspace/xcuserdata/
UserInterfaceState.xcuserstate
# Xcode compilation products
DerivedData/
build/
# Xcode old version temporary files
*.mode1v3
*.mode2v3
*.perspectivev3
*.pbxuser
# Compilation products
*.o
*.obj
*.out
*.exe
Then submit.
This will make the Git repository cleaner.
git init in the project root directory after creating .gitignore and submit everything in the file.Then you can delete the content in .git/info/exclude (it doesn’t matter whether you delete it or not).
OK, now your Xcode project’s git is basically set up.
