Usage & Example

Connect

// Example Struct
structMovie{letid:Stringlettitle:StringletreleaseDate:Dateletdesc:String}
// Struct connect Entity
extensionMovie:Entitable{
// Create toEntity Function
func toEntity(in context:NSManagedObjectContext)->MovieEntity{letentity:MovieEntity=.init(context: context)
entity.id = id
entity.title = title
entity.releaseDate = releaseDate
entity.desc = desc
return entity
}}
// Entity connect Struct
extensionMovieEntity:Objectable{
// Create toObject Function
publicfunc toObject()->someEntitable{returnMovie(id: id ??UUID().uuidString,
title: title ??"unknown",
releaseDate: releaseDate ??Date(),
desc: desc ??"")}}
