Unable to compile on Linux

[NuttyShrimp]

Hey,

I'm very interested in this library and want to try it out for my project.
I develop & want to deploy the project on Linux, but was unable to compile the project (as a dependency & just from the root of this repo).
My setup is using the latest swift version as of now, 6.3.1.
The following errors are thrown:

.../ReerJSON/Sources/ReerJSON/JSONDecoderImpl.swift:270:25: error: 'let' binding pattern cannot appear in an expression
 268 |             }
 269 |             return date
 270 |         case .formatted(let formatter):
     |                         `- error: 'let' binding pattern cannot appear in an expression
 271 |             let string = try unboxString(from: value, for: codingPathNode, additionalKey)
 272 |             guard let date = formatter.date(from: string) else {

.../ReerJSON/Sources/ReerJSON/JSONEncoderImpl.swift:286:25: error: 'let' binding pattern cannot appear in an expression
284 |         case .iso8601:
285 |             return wrapString(_iso8601Formatter.string(from: date))
286 |         case .formatted(let formatter):
    |                         `- error: 'let' binding pattern cannot appear in an expression
287 |             return wrapString(formatter.string(from: date))
288 |         case .custom(let closure):

I did some quick digging and found out that the formatted strategy is not implemented in the same place as the others. It needs to be provided by the swift-corelibs-foundation as this depends on the ObjC runtime on MacOS. But for some reason it's not being picked up as an option when running the switch case
