SwiftFormat / SwiftLint 기초

포맷 및 린트가 필요한 이유

SwiftFormat 시작하기

// Install & run (examples):
//   mint install nicklockwood/SwiftFormat     // via Mint
//   swiftformat .                             // format repo
//   swiftformat Sources --config .swiftformat // use config file
//
// Minimal .swiftformat (put in repo root):
// --ifdef no
// --wrapcollections before-first
// --maxwidth 100
print("SwiftFormat: run to auto-format code consistently")

SwiftLint 기초

// Install & run (examples):
//   brew install swiftlint         // macOS example
//   swiftlint lint                 // check whole repo
//   swiftlint lint --strict        // fail on warnings in CI
//
// Minimal .swiftlint.yml (example):
// disabled_rules:
//   - trailing_whitespace
// opt_in_rules:
//   - empty_count
// line_length: 100
// identifier_name:
//   min_length: 3
print("SwiftLint: report style issues with configurable rules")

위반 사항에서 깔끔한 코드로

// BEFORE (bad spacing, short name, unused let)
//let x=1
//print(  "Hi"  )
//
// AFTER (formatted & lint-friendly):
let count = 1
print("Hi")
print("count =", count)

자동화 작업 흐름

// Simple pre-commit idea (document in README):
//   swiftformat . && swiftlint lint --strict
//
// GitHub Actions (sketch) — put in CI config, not here:
//   - run: swiftformat --version && swiftformat .
//   - run: swiftlint lint --strict
//
// Tip: start lenient (warnings), then turn strict in CI once the repo is clean.
print("Automate: run format+lint locally and in CI")
