How do I add Natalie to my Xcode project?

Add a Run Script Phase in Build Phases with the script from the README, adjusting the path to the natalie binary. Place it above the compilation phase to ensure the generated Swift file is updated before each build, automating code generation.

Natalie vs R.swift for type-safe resources in Swift?

Natalie focuses specifically on storyboards, segues, and reusable views, while R.swift handles a wider range of resources like images, fonts, and nibs. Choose Natalie for deep storyboard integration; R.swift for broader resource management across your app.

Does Natalie work with SwiftUI?

No, Natalie is designed for UIKit and AppKit storyboards only. SwiftUI uses a declarative syntax without storyboards, so Natalie is not applicable for SwiftUI-based projects.

How to handle multiple storyboards with Natalie?

Natalie can process a folder containing multiple storyboard files, generating a single Swift file with enums for each storyboard under the `Storyboards` struct. This organizes all storyboards in one place for easy, type-safe access.

Troubleshooting: Natalie run script not updating file?

Check that the script has correct permissions and paths, and ensure storyboard files are newer than the generated Swift file. The script uses `find` to detect changes; verify it's placed above the compilation phase in Xcode and that the output path is writable.

Is Natalie actively maintained?

The README shows branches for older Swift versions, but the main branch may not be frequently updated. Check the GitHub repository for recent commits or issues to assess current maintenance, as it's labeled a proof-of-concept.

Natalie — Swift Storyboard Code Generator

What is Natalie?

Natalie is a Swift command‑line application that generates type‑safe Swift code from storyboard files. It creates enums and extensions that replace string‑based identifiers for segues, storyboards, and reusable views with compile‑time‑checked types, reducing errors and improving developer experience in UIKit/AppKit projects.

Target Audience

iOS and macOS developers who use Storyboards in their Swift projects and want to eliminate fragile string identifiers for segues, storyboard instantiation, and reusable view cells.

Value Proposition

Developers choose Natalie because it provides compile‑time safety for Storyboard operations without requiring a rewrite of their UI layer. It integrates seamlessly into Xcode builds, automatically keeping generated code in sync, and reduces boilerplate while preventing common runtime crashes from typos in string identifiers.

Natalie - Storyboard Code Generator (for Swift)

Use Cases

Best For

Eliminating string literals for segue identifiers in prepareForSegue
Safely instantiating view controllers from storyboards using type‑safe enums
Dequeuing table view and collection view cells without hard‑coded reuse identifiers
Automatically generating Swift code from storyboards on every Xcode build
Reducing runtime crashes due to typos in storyboard‑related strings
Adding compile‑time checks to Storyboard‑based iOS/macOS projects

Not Ideal For

SwiftUI-based projects where Storyboards are not used
Teams that prefer fully programmatic UI without any Interface Builder dependencies
Projects requiring support for XIB files or other UI formats beyond Storyboards
Environments with strict security policies that restrict running external command-line tools during builds

Pros & Cons

Pros

Type-Safe Storyboard Access

Generates an enum `Storyboards` with methods like `instantiateInitialViewController()` to replace `UIStoryboard(name:, bundle:)` calls, eliminating error-prone string literals for storyboard names.

Segue Enumeration

Extends each view controller with a `Segue` enum providing strongly-typed identifiers, kind, and destination types, usable in `prepareForSegue` and `performSegue` for compile-time safety.

Reusable View Identifiers

Creates `Reusable` enums for table/collection view cells, enabling `dequeueReusableCell` calls without string literals and `registerReusableCell` with type-safe identifiers, as shown in the UITableView examples.

Color Asset Support

Generates static `UIColor`/`NSColor` properties for named colors used in storyboards, available for iOS 11+ and macOS 10.13+, reducing hard-coded color strings.

Xcode Integration

Can be added as a Run Script Phase to automatically regenerate code when storyboards change, keeping the generated file up-to-date with every build, as detailed in the installation instructions.

Cons

Proof-of-Concept Limitations

The README describes it as a 'proof-of-concept implementation,' which may imply incomplete features, less active maintenance, or instability compared to production-ready tools.

Swift Version Fragmentation

Separate branches for Swift 3.x, 2.x, and 1.x indicate compatibility issues and potential breaking changes with Swift updates, requiring manual branch management and increasing setup complexity.

Manual Setup Complexity

Integrating with Xcode requires adding a custom Run Script Phase and configuring paths to the natalie binary, which can be error-prone and difficult for teams unfamiliar with build processes.

Limited to Storyboards

Only supports .storyboard files; it does not generate code for XIB files or other UI components, limiting its utility in projects with mixed UI formats or programmatic views.
