Tddworks Claude Skills IOS App Scaffold

iOS App Scaffold

Scaffold iOS apps with Tuist, Swift 6, and layered architecture.

Quick Start

Run the scaffold script:

python3 scripts/scaffold.py <AppName> <output-directory> [--bundle-id <id>] [--team-id <id>]

Example:

python3 scripts/scaffold.py MyApp /Users/me/projects --bundle-id com.mycompany.myapp --team-id ABC123

Then generate and open:

cd /Users/me/projects/MyApp
tuist generate
open MyApp.xcworkspace

Architecture

For detailed patterns, see references/architecture.md.

After Scaffolding

1. Replace example files: Edit Example.swift, ExampleRepository.swift, LocalExampleRepository.swift
2. Add domain models: Create models in Sources/Domain/Models/
3. Define protocols: Add repository protocols in Sources/Domain/Protocols/
4. Implement persistence: Add SwiftData entities in Sources/Infrastructure/Local/
5. Build UI: Create views in Sources/App/Views/

Adding Dependencies

Edit Project.swift packages array:

packages: [
    .remote(url: "https://github.com/Kolos65/Mockable.git", requirement: .upToNextMajor(from: "0.5.0")),
    // Add more packages here
],

Then add to target dependencies:

dependencies: [
    .package(product: "PackageName"),
]

Key Patterns

Domain models are rich - Include computed properties and business logic:

public struct Order: Identifiable, Codable, Sendable {
    public var items: [Item]
    public var total: Decimal { items.reduce(0) { $0 + $1.price } }
}

Protocols use @Mockable - Enables testing without real persistence:

@Mockable
public protocol OrderRepository: Sendable {
    func fetchAll() async throws -> [Order]
}

Views consume Domain directly - No ViewModel layer needed:

struct OrdersView: View {
    let orders: [Order]  // Domain model directly
}

Version Management

Version numbers are managed in Project.swift build settings:

settings: .settings(
    base: [
        "MARKETING_VERSION": "1.0.0",      // App Store version
        "CURRENT_PROJECT_VERSION": "1",     // Build number
    ],
    ...
)

The Info.plist references these via build setting variables:

• CFBundleShortVersionString → $(MARKETING_VERSION)
• CFBundleVersion → $(CURRENT_PROJECT_VERSION)

To bump version, edit Project.swift:

"MARKETING_VERSION": "1.1.0",
"CURRENT_PROJECT_VERSION": "2",

XCConfig

Build settings are managed via xcconfig files in Sources/App/Resources/XCConfig/:

Edit shared.xcconfig to customize:

PRODUCT_BUNDLE_IDENTIFIER = com.yourcompany.app
DEVELOPMENT_TEAM = YOUR_TEAM_ID
IPHONEOS_DEPLOYMENT_TARGET = 18.0
