Modern Swift concurrency with async/await, actors, TaskGroup, Sendable, and proper actor isolation for thread-safe iOS development.
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 Concurrency Skill
Master Swift 6 structured concurrency for safe, efficient concurrent code. Covers async/await, actors, tasks, and the Sendable protocol.
## async/await Fundamentals
### Basic Async Functions
```swift
// Async function declaration
func fetchUser(id: String) async throws -> User {
let url = URL(string: "https://api.example.com/users/\(id)")!
let (data, response) = try await URLSession.shared.data(from: url)
guard let httpResponse = response as? HTTPURLResponse,
httpResponse.statusCode == 200 else {
throw NetworkError.invalidResponse
}
return try JSONDecoder().decode(User.self, from: data)
}
// Calling async functions
func loadProfile() async {
do {
let user = try await fetchUser(id: "123")
print("Loaded: \(user.name)")
} catch {
print("Error: \(error)")
}
}
```
### Async Properties
```swift
struct RemoteImage {
let url: URL
var data: Data {
get async throws {
let (data, _) = try await URLSession.shared.data(from: url)
return data
}
}
}
```

How to install
mdr add jordancoin/ios-skills-collection/Swift Concurrency@sha256:38dccab3dec63370The line at the top of this page pins the label v1.0.0, 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.
