Advent Of Code 2022

My AoC 2022 Solutions in Swift

Overview

All code for all days is compiled into a single macOS commandline binary, which can be run either from within Xcode or from Terminal.

Each day has at least 3 associated source files:

• DayX.swift for the solution code
• DayX+Input.swift for the puzzle input, not included in this repo for legal reasons.
• DayXTests.swift for the test suite, if the puzzle has test cases

AoC.swift has the main() function which simply runs one (or all) of the puzzles.

The code relies on my own AoCTools package where I started collecting utility functions for things frequently used in AoC, such as 2d and 3d points, hexagonal grids, an A* pathfinder and more.

Xcode

Open the project via the Package.swift file (xed . from Terminal in the project directory). By default, hitting Cmd-R will run the puzzle for the current calendar day. To override this, change defaultDay in AoC.swift.

Cmd-U runs the test suite for all 25 days. Run individual tests by clicking on them in the Test Inspector (Cmd-6)

Commandline

From the commandline, use swift run or swift run -c release.

To run the puzzle for a specific day without changing AoC.swift, use swift run AdventOfCode X to run day X. X can be a number from 1 to 25 or all.

To run tests, use swift test for all tests, or e.g. swift test --filter AoCTests.Day02 to run the tests for day 2.

Puzzle Inputs

Use the included input.sh script to download your puzzle input. To be able to run this script, grab the session cookie from adventofcode.com and create a .aoc-session file with the contents. input.sh downloads the input for the current day by default, use input.sh X to download day X's input.
