CoreDataオブジェクトの属性が次のオブジェクトの作成時に消えています

Question

私はいくつかのデフォルトデータを作成し、最初の起動時にそれをcoredataに保存しますが、作成中に何かがうまくいかず、何か分かりません。

を（それが重要ならばsugarRecordを使用して）これらは創造のための機能：

デフォルトdataLayout（正常に動作します）

func createDefaultDataLayout() { 
    guard let db = db else { return } 
    do { 
     try db.operation { (context, save) throws -> Void in 
      let defaultData: TMDataLayout = try! context.create() 
      defaultData.id = 999 

      let spot1: TMData = (try! context.fetch(FetchRequest<TMData>().filtered(with: "id", equalTo: "1")).first)! 
      spot1.spot = 1 
      let spot2: TMData = (try! context.fetch(FetchRequest<TMData>().filtered(with: "id", equalTo: "6")).first)! 
      spot2.spot = 2 
      let spot3: TMData = (try! context.fetch(FetchRequest<TMData>().filtered(with: "id", equalTo: "8")).first)! 
      spot3.spot = 3 
      let spot4: TMData = (try! context.fetch(FetchRequest<TMData>().filtered(with: "id", equalTo: "19")).first)! 
      spot4.spot = 4 

      defaultData.data = [spot1, spot2, spot3, spot4] 
      save() 
     } 
    } catch { 
     print("Error creating default data layout") 
    } 
} 

デフォルトの活動、デフォルトを使用してdataLayout

func createDefaultActivities() { 
    guard let db = db else { return } 
    let defaultPredicate: NSPredicate = NSPredicate(format: "id == %@", "0") 

    do { 
     try db.operation { (context, save) throws -> Void in 

      let defaultDataLayout = try! context.fetch(FetchRequest<TMDataLayout>().filtered(with: defaultPredicate)).first 
      let defaultSettings = try! context.fetch(FetchRequest<TMSettingsLayout>().filtered(with: defaultPredicate)).first 

      let chosen: TMActivity = try! context.create() 
      chosen.id = 999 
      chosen.title = L10n.Activity.running 
      chosen.iconName = "running" 
      chosen.dataLayout = defaultDataLayout 
      chosen.settingsLayout = defaultSettings 
      chosen.goal = try! context.fetch(FetchRequest<TMGoal>().filtered(with: "title", equalTo: L10n.Goal.Nothing.title)).first 
      chosen.isPartOfWorkout = false 
      print(chosen) 

      let walking: TMActivity = try! context.create() 
      walking.id = 1 
      walking.title = L10n.Activity.walking 
      walking.iconName = "walking" 
      walking.dataLayout = defaultDataLayout 
      walking.settingsLayout = defaultSettings 
      walking.isPartOfWorkout = false 
      print(chosen) 

      save() 
     } 
    } catch { 
     print("Something went wrong setting up core data (dataManager)") 
    } 
} 

「選択された」2つのプリントは何か違うものを与え、オブジェクトが最初に正しいものをプリントし、dataLayoutとsettingsLayoutがセットされますが、2番目のものは消えてしまいます赤。同じ方法で目標を取得して設定すると、はのオブジェクトに残ります。

どこが間違っていますか？

ここで比較

func createGoalObjects() { 
    guard let db = db else { return } 
    do { 
     try db.operation { (context, save) throws -> Void in 
      let duration: TMGoal = try! context.create() 
      duration.id = 1 
      duration.title = L10n.Goal.Duration.title 
      duration.iconName = "duration" 
      duration.amount = 0 
      duration.descriptionString = L10n.Goal.Duration.amount(Int(duration.amount)) 

      let pace: TMGoal = try! context.create() 
      pace.id = 2 
      pace.title = L10n.Goal.Pace.title 
      pace.iconName = "pace" 
      pace.amount = 0 
      pace.descriptionString = L10n.Goal.Pace.amount(Int(duration.amount)) 

      let distance: TMGoal = try! context.create() 
      distance.id = 3 
      distance.title = L10n.Goal.Distance.title 
      distance.iconName = "distance" 
      distance.amount = 0 
      distance.descriptionString = L10n.Goal.Distance.amount(duration.amount) 

      let calories: TMGoal = try! context.create() 
      calories.id = 4 
      calories.title = L10n.Goal.Calories.title 
      calories.iconName = "calories" 
      calories.amount = 0 
      calories.descriptionString = L10n.Goal.Calories.amount(Int(duration.amount)) 

      let nothing: TMGoal = try! context.create() 
      nothing.id = 5 
      nothing.title = L10n.Goal.Nothing.title 
      nothing.iconName = "nothing" 
      nothing.amount = 0 
      nothing.descriptionString = L10n.Goal.Nothing.amount 

      save() 
     } 
    } catch { 
     print("Error creating default data layout") 
    } 
} 

のための目標の作成funcが私が得る2枚のプリントされている：

<TMActivity: 0x1c40990a0> (entity: TMActivity; id: 0x1c422d2c0 <x-coredata:///TMActivity/tA820CA64-1F5A-480D-A631-0BC3E05FFC9237> ; data: { 
    dataLayout = "0xd000000000040002 <x-coredata://62477925-6CCB-472D-8C45-BD6731B59AA6/TMDataLayout/p1>"; 
    goal = "0xd0000000000c0006 <x-coredata://62477925-6CCB-472D-8C45-BD6731B59AA6/TMGoal/p3>"; 
    iconName = running; 
    id = 999; 
    isPartOfWorkout = 0; 
    partId = 0; 
    parts =  (
    ); 
    settingsLayout = "0xd000000000040004 <x-coredata://62477925-6CCB-472D-8C45-BD6731B59AA6/TMSettingsLayout/p1>";
