# Utility
|
||
|
|
The general-purpose helpers the **Loud** services share: small, single-purpose methods with no dependencies beyond Foundation and no ties to any web framework.
|
||
|
|
|
||
|
|
## Overview
|
||
|
|
The package provides, grouped by role:
|
||
|
|
| Role | Types |
|
||
|
|
| --- | --- |
|
||
|
|
| Validation | `NormalizeEmail`, which reduces a submitted email address to its canonical form |
|
||
|
|
|
||
|
|
## Design rules
|
||
|
|
- **Dependency-free.** A helper belongs here only while it needs nothing beyond Foundation; one that grows a framework dependency belongs in the package owning that framework's concerns (e.g. `Infrastructure` for Hummingbird).
|
||
|
|
- **Method structs.** Helpers hold their lifetime-fixed configuration in `init` and take only per-call inputs in `callAsFunction`.
|
||
|
|
|
||
|
|
## Layout
|
||
|
|
Sources are split by visibility, then by kind, one type per file:
|
||
|
|
```
|
||
|
|
Sources/
|
||
|
|
└── Public/
|
||
|
|
└── Methods/ NormalizeEmail
|
||
|
|
Tests/
|
||
|
|
├── Cases/ the test suites, mirroring the Sources/ layout
|
||
|
|
└── Utils/ the suite Tag constants
|
||
|
|
```
|
||
|
|
|
||
|
|
## Testing
|
||
|
|
Every suite carries a tag naming the kind of API it exercises — `.method`, declared in `Tests/Utils/Extensions/Tag+Constants.swift` — so test plans and result summaries can slice the run by kind. A new suite must adopt the tag matching its subject (or add a tag there if none fits).
|
||
|
|
|
||
|
|
## Requirements
|
||
|
|
- Swift 6.3 toolchain (`swift-tools-version:6.3`).
|
||
|
|
- macOS 15, matching the sibling `Infrastructure`, `Localization`, and `Persistence` packages (the services deploy to Linux containers; the packages carry no UI platforms).
|
||
|
|
- No package dependencies — Foundation only.
