Required Instance Methodswift 6.0.1Swift
nestedContainer(keyedBy:)
Decodes a nested container keyed by the given type.
mutating func nestedContainer<NestedKey>(keyedBy type: NestedKey.Type) throws -> KeyedDecodingContainer<NestedKey> where NestedKey : CodingKey Parameters
- type
The key type to use for the container.
Returns
A keyed decoding container view into self.
Throws
DecodingError.typeMismatch if the encountered stored value is not a keyed container.
Other requirements
Instance members
var codingPath: [any CodingKey]The path of coding keys taken to get to this point in decoding.
