Swift Code Generator
Generate modern Swift code from natural language descriptions for iOS, macOS, and server-side development. AI automatically creates type-safe code with optionals, closures, protocols, and SwiftUI views. Handles Codable models, async/await patterns, Combine publishers, and UIKit controllers instantly without manual boilerplate.

How It Works
- Step 1: Describe your Swift requirement in plain English, such as "create SwiftUI view with list and navigation" or "implement Codable model for JSON parsing".
- Step 2: The AI analyzes your request and identifies Swift-specific patterns including optional handling, protocol-oriented design, value types vs reference types, and memory management with ARC.
- Step 3: Advanced language models generate idiomatic Swift code with proper access control, guard statements for early exits, and modern Swift 5.9+ features like async/await and structured concurrency.
- Step 4: Download clean Swift code with appropriate import statements, proper formatting following Swift style guidelines, and Xcode-ready syntax for immediate integration into your iOS or macOS project.
Code Generation Examples
Example 1: SwiftUI View with State Management
Create a SwiftUI view with a counter that increments when a button is tapped import SwiftUI
struct CounterView: View {
@State private var count = 0
var body: some View {
VStack(spacing: 20) {
Text("Count: \(count)")
.font(.largeTitle)
.fontWeight(.bold)
Button(action: {
count += 1
}) {
Text("Increment")
.padding()
.background(Color.blue)
.foregroundColor(.white)
.cornerRadius(10)
}
}
.padding()
}
}
struct CounterView_Previews: PreviewProvider {
static var previews: some View {
CounterView()
}
} Key Changes:
The generated Swift code demonstrates modern SwiftUI declarative syntax with the @State property wrapper for reactive state management. When the count changes, SwiftUI automatically recomputes the view hierarchy and updates the UI. The VStack provides vertical layout with spacing, while the Text view uses string interpolation for dynamic content. The Button uses a trailing closure for the action handler, following Swift's closure syntax conventions. The code includes a PreviewProvider for Xcode canvas previews, enabling live UI development. This pattern follows Apple's recommended SwiftUI architecture and compiles without warnings in Xcode 15+.
Example 2: Codable Model with JSON Parsing
Create a User model that can parse JSON with id, name, email, and optional phone number import Foundation
struct User: Codable, Identifiable {
let id: Int
let name: String
let email: String
let phone: String?
enum CodingKeys: String, CodingKey {
case id
case name
case email
case phone = "phone_number"
}
}
// Usage example
func parseUser(from jsonData: Data) throws -> User {
let decoder = JSONDecoder()
decoder.keyDecodingStrategy = .convertFromSnakeCase
return try decoder.decode(User.self, from: jsonData)
}
// Example with error handling
let jsonString = """
{
"id": 1,
"name": "John Doe",
"email": "[email protected]",
"phone_number": "+1234567890"
}
"""
if let data = jsonString.data(using: .utf8) {
do {
let user = try parseUser(from: data)
print("Parsed user: \(user.name)")
} catch {
print("Failed to parse: \(error)")
}
} Key Changes:
This Swift code showcases the Codable protocol for automatic JSON serialization with custom key mapping using CodingKeys enum. The optional phone property demonstrates Swift's type-safe nil handling—the compiler enforces unwrapping before use. The struct conforms to Identifiable for SwiftUI List integration. The parseUser function uses throws for explicit error propagation, following Swift's error handling model. JSONDecoder's keyDecodingStrategy converts snake_case JSON keys to camelCase Swift properties automatically. The do-catch block provides compile-time safety for error handling. This pattern is production-ready for REST API integration and follows Apple's Foundation framework conventions.
Frequently Asked Questions
How do I generate Swift code?
Describe what you want to build in plain English, select Swift as your target language, and click "Generate Code". Our AI will create clean, functional Swift code based on your description.
Is there a free trial for the Swift code generator?
Yes! Every new user gets 5 free lifetime credits to try our tools. After that, purchase credits starting at $10 for 100 credits. Credits never expire and there are no subscriptions.
What kind of Swift code can I generate?
You can generate any Swift code including functions, classes, algorithms, API integrations, data structures, and complete applications. Just describe your requirements in detail.
Is the generated Swift code production-ready?
Yes, our AI generates clean, well-structured Swift code following best practices. However, we recommend reviewing and testing all generated code before production use.
Can I customize the generated Swift code style?
Yes, you can specify coding conventions, naming patterns, and style preferences in your description. The AI will adapt the generated Swift code accordingly.
