“No exact matches in call to initializer” when reading data

[WesSouza]

I am trying to use this package on a new project, and I'm unable to access any values on a created Document while following the same method as the README states.

The compiler is unable to use the value:

let data: Document = [ "type": "createSession" ]
let type = String(data["type"])
//         ^ No exact matches in call to initializer 
print(type);

If I add a breakpoint and observe the value using lldb, it does have a debugger output, so the data exists:

(lldb) vo data
(BSON.Document) data = ▿ ["type": "createSession"]
  ▿ storage : ByteBuffer (...)

Did this stop working on newer versions of Swift?

Hello @WesSouza, which version of BSON are you using? The readme still describes the old 5.x version of BSON. The latest version of BSON which is used in MongoDB is 7.x.

@Joannis I have installed this using Swift Package Manager, so I'm using version 7.0.23.

Is there a place I can find references on how to encode and decode data? I'm using this for a personal project to decode binary WebSocket messages.

Would also be super happy to contribute to an update to README if I can find more data about it.

If you're looking for Codable, be sure to use BSONEncoder and BSONDecoder.

I've just updated the docs, but feel free to make a PR for any info you might find helpful.
