public func decodeIfPresent(_ type: [String : any Sendable].Type, forKey key: K) throws -> [String : any Sendable]?

Parameters

`type`	The type of dictionary to decode
`key`	The coding key to decode from

Declaration

Swift

public func decode(_ type: [any Sendable].Type, forKey key: K) throws -> [any Sendable]

Parameters

`type`	The type of array to decode
`key`	The coding key to decode from

Return Value

An array of Sendable values


                    
                    
                    decodeIfPresent(_:forKey:)

Decodes an array of Sendable values if present for a given key.

Throws

DecodingError if the value cannot be decoded

Declaration

Swift

public func decodeIfPresent(_ type: [any Sendable].Type, forKey key: K) throws -> [any Sendable]?

Parameters

`type`	The type of array to decode
`key`	The coding key to decode from

Return Value

                    decode(_:)

Decodes a dictionary with string keys and Sendable values from the current container.

This method iterates through all keys in the container and attempts to decode each value as a Bool, String, Int, Double, nested dictionary, or nested array.

Throws

DecodingError if the container cannot be processed

Declaration

Swift

public func decode(_ type: [String : any Sendable].Type) throws -> [String : any Sendable]

Parameters


                                type

The type of dictionary to decode

Return Value

A dictionary with string keys and Sendable values containing all successfully decoded values
