# uikit-guidelines-cursorrules-prompt-file

A rule that enforces programmatic Swift UIKit layouts without Storyboards. It standardizes SnapKit for Auto Layout, isolates data models from UI views, and handles events with closures.

## What it does

This prompt guides the AI assistant to write clean Swift code for UIKit without touching Storyboards or XIB files. All UI elements, such as `UIView`, `UIButton`, and `UITableViewCell`, are generated strictly in code. Auto Layout relies solely on SnapKit instead of `NSLayoutConstraint` while accounting for Dynamic Type and Safe Area boundaries.

Views stay completely decoupled from DTOs and models. The rule directs the agent to pass data via Factory, Builder, or ViewController patterns. External actions emit closures that pass `self` back to identify the event trigger. SnapKit must be installed in your project, or the generated code will fail to build. Existing code comments remain untouched.

## Install

### Cursor (native platform)

**Manually: put the files in place**
- File: `.cursor/rules/uikit-guidelines-cursorrules-prompt-file.mdc` — Frontmatter: description, globs, alwaysApply

### Claude Code

**Manually: put the files in place**
- File: `.claude/rules/uikit-guidelines-cursorrules-prompt-file.md` — The paths frontmatter field limits the files: move globs from the source into paths

### Codex

**AGENTS.md**
- Codex reads AGENTS.md: paste the rule text there

### GitHub Copilot

**Manually: put the files in place**
- File: `.github/instructions/uikit-guidelines-cursorrules-prompt-file.instructions.md` — The applyTo field sets which files it applies to: move globs from the source into applyTo

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/rules/uikit-guidelines-cursorrules-prompt-file.md`

### Cline

**Manually: put the files in place**
- File: `.clinerules/uikit-guidelines-cursorrules-prompt-file.md`

## When to use it
- build programmatic iOS layouts without Storyboards
- replace verbose NSLayoutConstraint code with SnapKit DSL
- decouple Swift data models and DTOs from UIKit views
- handle UI interactions using closures that send component references

## Example prompts
- Create a profile screen in UIKit with an avatar image and an edit button
- Build a custom news feed table cell configured via a factory
- Generate a reusable button that sends its tap event through a closure

you are an expert in coding with swift, iOS, UIKit. you always write maintainable code and clean code.
focus on latest documentation and features.
your descriptions should be short and concise.
don't remove any comments.


UIKit UI Design Principles:
1. Auto Layout: Implement responsive layouts using SnapKit only (avoid NSLayoutConstraint for better readability), support Dynamic Type and Safe Area
2. Programmatic UI: Avoid Storyboards/XIBs, implement all UI components directly in code (UIView, UIButton, UITableViewCell). Use view composition and custom view subclasses for reusability
3. UI Components must not directly access models or DTOs. Use ViewController, Factory, or Builder patterns following OOP/MVC/MVVM principles. Below are good and bad practice examples:

good practice:
```swift
let user = User(name: "Alice", email: "john@example.com")
let factory = UserFactory()
/// This way UserView doesn't access User model directly, following Apple's MVC principles
let userView = factory.createUserView(user: user)
```

bad practice:
```swift
let user = User(name: "Alice", email: "john@example.com")
/// This exposes UserView to User model, violating MVC principles
let userView = UserView(user: user)
```

4. UI components should pass events using closures, and the closure must pass 'self' as a parameter to allow external objects to identify the source component

```swift
class SampleView: UIView {
    var didTapButton: ((SampleView) -> Void)?
    private let button = UIButton()
    override init(frame: CGRect) {
        super.init(frame: frame)
        setupUI()
        button.addTarget(self, action: #selector(buttonTapped), for: .touchUpInside)
    }

    private func setupUI() {
        // setup UI
    }

    @objc private func buttonTapped() {
        didTapButton?(self)
    }
}
```
