Cracking The Coding Interview

Build Status Swift 4

Solutions of Cracking The Coding Interview written in Swift.

Tests

Tests are updated by using Sourcery. When editing tests (add, remove, disable, enable tests) run sourcery from the root folder. You can unzip sourcery's latest binary and put the bin directory in the root directory, then run bin/sourcery from the root directory.

Run the test by using SPM's test command:

$ swift test

You can also run individual tests by using its number.

$ swift test --filter 2.1
