Instance members

var capacity: Int
The total number of key-value pairs that the dictionary can contain without allocating new storage.
var count: Int
The number of key-value pairs in the dictionary.
var customMirror: Mirror
A mirror that reflects the dictionary.
var debugDescription: String
A string that represents the contents of the dictionary, suitable for debugging.
var description: String
A string that represents the contents of the dictionary.
var endIndex: Dictionary<Key, Value>.Index
The dictionary’s “past the end” position—that is, the position one greater than the last valid subscript argument.
var isEmpty: Bool
A Boolean value that indicates whether the dictionary is empty.
var keys: Dictionary<Key, Value>.Keys
A collection containing just the keys of the dictionary.
var startIndex: Dictionary<Key, Value>.Index
The position of the first element in a nonempty dictionary.
var values: Dictionary<Key, Value>.Values
A collection containing just the values of the dictionary.
subscript(Key) -> Value?
Accesses the value associated with the given key for reading and writing.
subscript(Dictionary<Key, Value>.Index) -> Dictionary<Key, Value>.Element
Accesses the key-value pair at the specified position.
subscript(Key, default: @autoclosure () -> Value) -> Value
Accesses the value with the given key, falling back to the given default value if the key isn’t found.
func compactMapValues<T>((Value) throws -> T?) rethrows -> Dictionary<Key, T>
Returns a new dictionary containing only the key-value pairs that have non-nil values as the result of transformation by the given closure.
func filter((Dictionary<Key, Value>.Element) throws -> Bool) rethrows -> [Key : Value]
Returns a new dictionary containing the key-value pairs of the dictionary that satisfy the given predicate.
func index(after: Dictionary<Key, Value>.Index) -> Dictionary<Key, Value>.Index
func index(forKey: Key) -> Dictionary<Key, Value>.Index?
Returns the index for the given key.
func makeIterator() -> Dictionary<Key, Value>.Iterator
Returns an iterator over the dictionary’s key-value pairs.
func mapValues<T>((Value) throws -> T) rethrows -> Dictionary<Key, T>
Returns a new dictionary containing the keys of this dictionary with the values transformed by the given closure.
func merge([Key : Value], uniquingKeysWith: (Value, Value) throws -> Value) rethrows
Merges the given dictionary into this dictionary, using a combining closure to determine the value for any duplicate keys.
func merge<S>(S, uniquingKeysWith: (Value, Value) throws -> Value) rethrows
Merges the key-value pairs in the given sequence into the dictionary, using a combining closure to determine the value for any duplicate keys.
func merging([Key : Value], uniquingKeysWith: (Value, Value) throws -> Value) rethrows -> [Key : Value]
Creates a dictionary by merging the given dictionary into this dictionary, using a combining closure to determine the value for duplicate keys.
func merging<S>(S, uniquingKeysWith: (Value, Value) throws -> Value) rethrows -> [Key : Value]
Creates a dictionary by merging key-value pairs in a sequence into the dictionary, using a combining closure to determine the value for duplicate keys.
func popFirst() -> Dictionary<Key, Value>.Element?
Removes and returns the first key-value pair of the dictionary if the dictionary isn’t empty.
func remove(at: Dictionary<Key, Value>.Index) -> Dictionary<Key, Value>.Element
Removes and returns the key-value pair at the specified index.
func removeAll(keepingCapacity: Bool)
Removes all key-value pairs from the dictionary.
func removeValue(forKey: Key) -> Value?
Removes the given key and its associated value from the dictionary.
func reserveCapacity(Int)
Reserves enough space to store the specified number of key-value pairs.
func updateValue(Value, forKey: Key) -> Value?
Updates the value stored in the dictionary for the given key, or adds a new key-value pair if the key does not exist.
