My AoC 2024 Solutions in Swift
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 usually has 3 associated source files:
DayX.swiftfor the solution codeDayX+Input.swiftfor the puzzle input. This file is created by running theinput.shscript (see below) but is not included in this repo for legal reasons.DayXTests.swiftfor the test suite, if the puzzle has test cases
AoC.swift has the main() function which runs one (or all) of the puzzles, then prints the solution(s) and the elapsed time.
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.
Open the project via the Package.swift file (xed . from Terminal in the project directory). Cmd-R will either run the puzzle for the current calendar day during December, or for all days in other months. 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)
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.Day02Tests to run the tests for day 2.
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.
