freezeray init

Initialize FreezeRay in your project by creating directory structure and adding the package dependency.

​
Synopsis

freezeray init [OPTIONS]

​
Description

The init command sets up FreezeRay in your project:
  1. Detects project type (Swift Package or Xcode Project)
  2. Creates directory structure (FreezeRay/Fixtures/ and FreezeRay/Tests/)
  3. Adds FreezeRay package dependency to Package.swift or Xcode project
Run this command once when you first add FreezeRay to your project.

​
Usage

​
Swift Package

cd YourSwiftPackage
freezeray init
What it does:
  • Creates FreezeRay/ directory structure
  • Adds dependency to Package.swift: 
    dependencies: [
    .package(url: "https://github.com/TrinsicVentures/FreezeRay.git", from: "0.4.0"),
]

​
Xcode Project

cd YourXcodeProject
freezeray init
What it does:
  • Creates FreezeRay/ directory structure
  • Adds FreezeRay package to Xcode project
  • Adds FreezeRay/ folder reference to project navigator (yellow folder)

​
Options

​
--package-path <PATH>

Specify path to FreezeRay package (for local development): 
freezeray init --package-path /path/to/FreezeRay
Use case: Testing local changes to FreezeRay package. Default: Uses GitHub release (https://github.com/TrinsicVentures/FreezeRay.git)

​
--skip-dependency

Skip adding FreezeRay dependency (only create directory structure): 
freezeray init --skip-dependency
Use case: You want to manually add the dependency or use a different version.

​
Directory Structure

After running init, your project will have: 
YourProject/
├── FreezeRay/
│   ├── Fixtures/         # Schema fixtures (created by freeze command)
│   ├── Tests/            # Scaffolded tests (created by freeze command)
│   └── README.md         # Usage guide
├── Package.swift         # (SPM) Updated with FreezeRay dependency
└── YourProject.xcodeproj # (Xcode) Updated with FreezeRay package
The FreezeRay/ directory is initially empty. It will be populated when you run freezeray freeze.

​
Examples

​
Basic initialization

cd MyApp
freezeray init
Output: 
🔹 FreezeRay Init

🔹 Detecting project type...
   Type: Xcode Project

🔹 Creating directory structure...
   ✅ Created FreezeRay/Fixtures/
   ✅ Created FreezeRay/Tests/

🔹 Adding FreezeRay dependency...
   ✅ Added FreezeRay package to Xcode project
   ✅ Added FreezeRay/ folder to project navigator

✅ FreezeRay initialized successfully!

📝 Next steps:
   1. Add @FreezeSchema(version: "1.0.0") to your schema
   2. Run: freezeray freeze 1.0.0
   3. Commit: git add FreezeRay/

​
Skip dependency installation

freezeray init --skip-dependency
Use this if you want to add the package manually through Xcode’s UI.

​
Local package development

freezeray init --package-path ../FreezeRay
Points to a local clone of FreezeRay for testing changes.

​
Requirements

  • macOS 14+
  • Xcode 15+ (for Xcode projects)
  • Swift 5.9+
  • Run from project root directory containing:
    • Package.swift (for Swift Packages), or
    • *.xcodeproj (for Xcode Projects)

​
Error Messages

​
”No Swift Package or Xcode project found”

Cause: Not running from project root directory Fix: 
cd YourProjectRoot  # Directory with Package.swift or *.xcodeproj
freezeray init

​
“FreezeRay dependency already exists”

Cause: FreezeRay is already added to your project Solution: This is fine! The init command is idempotent. Directory structure will be created if missing.

​
”Could not modify Package.swift”

Cause: Package.swift has unusual formatting Fix: Manually add FreezeRay to your Package.swift: 
dependencies: [
    .package(url: "https://github.com/TrinsicVentures/FreezeRay.git", from: "1.0.0"),
],
targets: [
    .target(
        name: "YourTarget",
        dependencies: ["FreezeRay"]
    ),
]

​
“Could not modify Xcode project”

Cause: Xcode project format issue or permissions Fix: Manually add FreezeRay in Xcode:
  1. File → Add Package Dependencies…
  2. Enter: https://github.com/TrinsicVentures/FreezeRay.git
  3. Select version 1.0.0 or later
  4. Add to your main app target

​
Next Steps

After initializing FreezeRay:
1

Annotate your schema

Add @FreezeSchema(version: "1.0.0") to your VersionedSchema
2

Freeze your schema

Run freezeray freeze 1.0.0 to create fixtures
3

Commit fixtures

Run git add FreezeRay/ and commit to your repository
4

Run tests
