Swift 辅助工具，可以更轻松地映射诸如 .mapKeys、.mapKeysAndValues、.mapValuesUsingKeys 之类的操作

示例

.mapKeys

let newDictionary = ["a": 1, "b": 2]
  .mapKeys { $0.uppercased() }

print(newDictionary) // ["A": 1, "B": 2]

.mapValuesUsingKeys

let newDictionary = ["a": 1, "b": 2].mapValuesUsingKeys { value, key in
  return "\(key)\(value)"
}

print(newDictionary) // ["a": "a1", "b": "b2"]

.mapKeysAndValues

let newDictionary = ["a": "x", "b": "y"].mapKeysAndValues { key, value in
  return (key.uppercased(), value.uppercased())
}

print(newDictionary) // ["A": "X", "B": "Y"]
