Swift Algorithms 1.2.0

Additions

• Sequences have new grouped(by:) and keyed(by:) methods, which simplify building dictionaries based on sequence elements: (#197)

  let evensOdds = (1...10).grouped(by: { $0.isMultiple(of: 2) ? "even" : "odd" })
  // ["even": [2, 4, 6, 8, 10], "odd": [1, 3, 5, 7, 9]]
  
  let animals = ["Aardvark", "Alpaca", "Armadillo", "Barracuda", "Buffalo", ...]
  let alphaAnimals = animals.keyed(by: \.first!, resolvingConflictsWith: { _, first, _ in first })
  // ["A": "Aardvark", "B": "Barracuda", ...]

• The endOfPrefix(while:) and startOfSuffix(while) methods are now public. These methods were previously implementation details of the trimming group of methods. (#211)

Fixes

• Documentation and performance improvements. (#202, #210)
