❗ [CoreStore: Assertion Failure] Field.Stored.swift:156 subscript(_enclosingInstance:wrapped:storage:)
↪︎ Attempted to access values from a 'ValueListGeneric' meta object. Meta objects are only used for querying keyPaths and infering types.

 var dbSchema = CoreStoreSchema(modelVersion: CDModels.latestModelVersion,
                                       entities: CDModels.latestEntitiesShema)

public enum CDModels  {
    
    typealias ValueListGeneric = CDModels.V1.ValueListGeneric
    
    static let latestEntitiesShema : [DynamicEntity] = [ValueListGeneric.schema()]
    static let latestModelVersion = CDModels.V1.name
}

then

extension CDModels.V1.ValueListGeneric {
    public static let schemaName: String = "ValueListGeneric"
    public static func schema() -> Entity<CDModels.V1.ValueListGeneric> {
        
        let indexOne: [PartialKeyPath<CDModels.V1.ValueListGeneric>] = [\CDModels.V1.ValueListGeneric.id, \CDModels.V1.ValueListGeneric.tableName]
        
        return Entity<CDModels.V1.ValueListGeneric>(self.schemaName,
                                        indexes: [indexOne],
                                        uniqueConstraints: [indexOne])
    }
}

its launching the assert from here

public init(_ type: O.Type, _ entityName: String, isAbstract: Bool = false, versionHashModifier: String? = nil, indexes: [[PartialKeyPath<O>]] = [], uniqueConstraints: [[PartialKeyPath<O>]]) {
        
        let meta = O.meta
        let toStringArray: ([PartialKeyPath<O>]) -> [KeyPathString] = {
            
            return $0.map {
                
                return (meta[keyPath: $0] as! AnyKeyPathStringConvertible).cs_keyPathString <--------- it's saying meta rawObject shouldn't be nil. But I'm just starting the datastack that isn't possible
            }
        }
        super.init(
            type: type,
            entityName: entityName,
            isAbstract: isAbstract,
            versionHashModifier: versionHashModifier,
            indexes: indexes.map(toStringArray),
            uniqueConstraints: uniqueConstraints.map(toStringArray)
        )
    }
