KeyedEncodingContainerProtocol issues with new Int128 type

Using Swift
1

Hi,

it's the first time I come with an error I have not the slightest idea on how to fix.
I just started implementing an Apache Avro Encoder and Decoder in Swift and I'm stuck in the first 5 minutes.

private struct AvroKeyedEncodingContainer<K: CodingKey>: KeyedEncodingContainerProtocol {
	typealias Key = K
	
	var codingPath: [any CodingKey]
	
	
	mutating func encodeNil(forKey key: K) throws {
		fatalError("Not implemented")

	}
	
	mutating func nestedContainer<NestedKey>(keyedBy keyType: NestedKey.Type, forKey key: K) -> KeyedEncodingContainer<NestedKey> where NestedKey : CodingKey {
		fatalError("Not implemented")

	}
	
	mutating func nestedUnkeyedContainer(forKey key: K) -> any UnkeyedEncodingContainer {
		fatalError("Not implemented")

	}
	
	mutating func superEncoder(forKey key: K) -> any Encoder {
		fatalError("Not implemented")

	}

	
	mutating func superEncoder() -> any Encoder {
		fatalError("Not implemented")

	}
	
	
}

I immediatley get the error Type 'AvroKeyedEncodingContainer<K>' does not conform to protocol 'KeyedEncodingContainerProtocol and get infos from Xcode that Candidate has non-matching type '<Self> (Int128, forKey: Self.Key) throws -> ()' (Swift.KeyedEncodingContainerProtocol) and Candidate has non-matching type '<Self> (UInt128, forKey: Self.Key) throws -> ()' (Swift.KeyedEncodingContainerProtocol).

I tried constraining my struct to macOS 15+ but this didn't change anything.

I checked the proposal as well as the protocol implementations and it looks exactly like the other implications for Int** so I have no idea what to do there.

Thanks for your help!

Nvm, the info message was wrong, it just showed int128 as it was the first one in the list. you need to add all the methods, then it works.
