base on Swift starter project for solving Advent of Code challenges. # Advent of Code Swift Starter Project [](https://swift.org) Daily programming puzzles at [Advent of Code](<https://adventofcode.com/>), by [Eric Wastl](<http://was.tl/>). This is a small example starter project for building Advent of Code solutions. ## Usage Swift comes with Xcode, or you can [install it](https://www.swift.org/install/) on a supported macOS, Linux, or Windows platform. If you're using Xcode, you can open this project by choosing File / Open and select the parent directory. If you prefer the command line, you can run the test suite with `swift test`, and run the output with `swift run`. If you're using Visual Studio Code to edit, you might find these Swift extensions useful: - [Swift](https://marketplace.visualstudio.com/items?itemName=swiftlang.swift-vscode) (provides core language edit / debug / test features) - [apple-swift-format](https://marketplace.visualstudio.com/items?itemName=vknabel.vscode-apple-swift-format) (supports the [swift-format](https://github.com/apple/swift-format) package) ## Challenges The challenges assume three files (replace 00 with the day of the challenge). - `Sources/Data/Day00.txt`: the input data provided for the challenge - `Sources/Day00.swift`: the code to solve the challenge - `Tests/Day00.swift`: any unit tests that you want to include To start a new day's challenge, make a copy of these files, updating 00 to the day number. ```diff // Add each new day implementation to this array: let allChallenges: [any AdventDay] = [ - Day00() + Day00(), + Day01(), ] ``` Then implement part 1 and 2. The `AdventOfCode.swift` file controls which challenge is run with `swift run`. Add your new type to its `allChallenges` array. By default it runs the most recent challenge. The `AdventOfCode.swift` file controls which day's challenge is run with `swift run`. By default that runs the most recent challenge in the package. To supply command line arguments use `swift run AdventOfCode`. For example, `swift run -c release AdventOfCode --benchmark 3` builds the binary with full optimizations, and benchmarks the challenge for day 3. ## Linting and Formatting Challenge source code can be linted and formatted automatically using the included dependency on `swift-format`. Lint source code with the following command: ```shell $ swift package lint-source-code ``` Format source code with the following command: ```shell $ swift package format-source-code Plugin ‘Format Source Code’ wants permission to write to the package directory. Stated reason: “This command formats the Swift source files”. Allow this plugin to write to the package directory? (yes/no) ``` To avoid the interactive prompt when formatting source code, use the `--allow-writing-to-package-directory` flag. ```shell $ swift package format-source-code --allow-writing-to-package-directory ``` swift-format will use the built-in default style to lint and format code. A `.swift-format` configuration file can be used to customize the style used, see [Configuration](https://github.com/apple/swift-format/blob/main/Documentation/Configuration.md) for more details.
