My solutions for Advent of Code 2023.

The challenges assume three files.

• Data/DayNN.txt: the input data provided for the challenge
• Sources/DayNN.swift: the solution
• Tests/DayNN.swift: unit tests

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.

$ swift package format-source-code --allow-writing-to-package-directory
