extension Dictionary: InitializeableOccupiable

  • Helper method to modify value at specific key

    Declaration

    Swift

    mutating func modifyValue(atKey key: Key, _ modifyValue: (_ element: inout Value?) throws -> ()) rethrows

  • Returns a new dictionary containing the keys of this dictionary with the values transformed by the given closure. Filters out keys with nil values.

    Declaration

    Swift

    func compactMapValues<T>(_ transform: (Dictionary.Value) throws -> T?) rethrows -> [Dictionary.Key : T]

    Parameters

    transform

    A closure that transforms a value. transform accepts each value of the dictionary as its parameter and returns a transformed value of the same or of a different type.

    Return Value

    A dictionary containing keys and transformed values of this dictionary.

  • Returns a new dictionary containing the values of this dictionary with the keys transformed by the given closure.

    Declaration

    Swift

    func mapKeys(_ transform: (Dictionary.Key) throws -> Dictionary.Key) rethrows -> [Dictionary.Key : Dictionary.Value]

    Parameters

    transform

    A closure that transforms a key.

    Return Value

    A dictionary containing transformed keys and values.

  • Map keys and values together into a new dictionary.

    Warning

    Resulting keys must be unique!

    Declaration

    Swift

    @inlinable
func mapDictionary<T, U>(_ transform: (_ key: Key, _ value: Value) throws -> (key: T, U)) rethrows -> [T : U] where T : Hashable
