swift-development SKILL.md skillA
swift-development from projanvil/mindforge is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add projanvil/mindforge/swift-development@git:20261009.b4230f2Pins git:20261009.b4230f2 in mdr.lock. Pin the fingerprint instead.

Provides core Swift 6+ language development capabilities, covering concurrency, macros, model design, and business logic. Use this skill when writing ViewModel, Service, or Repository layer code, defining data models, implementing algorithms, writing unit tests, or fixing concurrency warnings and data races.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Swift 6 Development Skill
## Instructions
Follow this guide when working on non-UI Swift code, business logic, algorithms, or the data layer. Your goal is to write high-performance, thread-safe, and expressive Swift code.
## What This Skill Does
- **Concurrent Programming**: Write safe concurrent code using Actors, async/await, Task, and TaskGroup.
- **Type Safety**: Define Sendable types and use Typed Throws for precise error handling.
- **Testing**: Write modern unit tests using the Swift Testing framework.
- **Data Processing**: Write Codable models and encapsulate JSON parsing and network requests.
- **Macros**: Use or create macros to reduce boilerplate.
## When to Use This Skill
Trigger scenarios:
- When writing ViewModel, Service, or Repository layer code.
- When defining data models (structs, enums).
- When implementing algorithms or utility functions.
- When writing unit tests.
- When fixing concurrency warnings or data races.
## Examples
### Example 1: Defining a Safe Actor Service
```swift
/// A thread-safe user data service
actor UserService {
private var cache: [String: User] = [:]
// Use typed throws to specify the error type explicitly

How to install
mdr add projanvil/mindforge/swift-development@sha256:14288d770ffc2a35The line at the top of this page pins the label git:20261009.b4230f2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
