I will try to save records with type:

Here is model:

import UIKit
import CoreData

class WindEntity: NSManagedObject {
@NSManaged var wind_id:String
@NSManaged var latitude:Double
@NSManaged var longitude:Double

func setInitialValues() {
    self.latitude = Double(arc4random_uniform(180)) - 90
    self.longitude = Double(arc4random_uniform(360)) - 180
    self.wind_id = NSUUID().uuidString.lowercased()
}

var coordinate: CLLocationCoordinate2D {
    get {
        
        return CLLocationCoordinate2DMake(
            self.latitude,
            self.longitude
        )
    }
    set {
        
        self.latitude = newValue.latitude
        self.longitude = newValue.longitude
    }
}

}

Save code:

class DBManager: NSObject {

static let sharedManager = DBManager()

let dataStack = DataStack(xcodeModelName: "Hunt")

private override init() {
    super.init()
    let migrationProgress = dataStack.addStorage(
        SQLiteStore(
            fileName: "Hunt.sqlite",
            configuration: "Default",
            localStorageOptions: .recreateStoreOnModelMismatch // optional. Provides settings that tells the DataStack how to setup the persistent store
        ),
        completion: { (result) -> Void in
            switch result {
            case .success(let storage):
                print("Successfully added sqlite store: \(storage)")
            case .failure(let error):
                print("Failed adding sqlite store with error: \(error)")
            }
        }
    )
    CoreStoreDefaults.dataStack = dataStack
  }

func saveWindModel(weather:WeatherModel) {
    dataStack.perform(
        asynchronous: { (transaction) -> Void in
            let wind = transaction.create(Into<WindEntity>())
            wind.setInitialValues()
            wind.coordinate = weather.location!.coordinate
            
            print("wind: \(wind) isUpdated \(wind.isUpdated)")
        },
        completion: { (result) -> Void in
            switch result {

            case .success:
                let people = try! self.dataStack.fetchAll(From<WindEntity>())
                print("people \(people)")
                
            case .failure(let error): print(error)
                
            }
        }
    )
}

}

After saving I will try to fetch items and have data: )

I'm not sure what the problem is. Your logs seem to show that
print("people \(people)")
is properly displaying the objects you created:
