倍数插入在核心数据

Question

我有很多的信息来重新填充我的数据库，这就是我该怎么办：

let notaryFeeGrid = NSEntityDescription.insertNewObject(forEntityName: "NotaryFeeGrid", into: context) as! NotaryFeeGrid 

notaryFeeGrid.id = 0 
notaryFeeGrid.notaryLoansAmount = 1000 
notaryFeeGrid.notaryFeeAmount = 510 

context.insert(notaryFeeGrid) 


let notaryFeeGrid2 = NSEntityDescription.insertNewObject(forEntityName: "NotaryFeeGrid", into: context) as! NotaryFeeGrid 

notaryFeeGrid2.id = 0 
notaryFeeGrid2.notaryLoansAmount = 3000 
notaryFeeGrid2.notaryFeeAmount = 530 

context.insert(notaryFeeGrid2) 

let notaryFeeGrid3 = NSEntityDescription.insertNewObject(forEntityName: "NotaryFeeGrid", into: context) as! NotaryFeeGrid 

notaryFeeGrid3.id = 0 
notaryFeeGrid3.notaryLoansAmount = 5000 
notaryFeeGrid3.notaryFeeAmount = 570 

context.insert(notaryFeeGrid3) 

它的完整代码的一小部分，我怎么能减少呢？

试试这个......创建公证项目的阵列..

更新：

func addNotary(_ context : NSManagedObjectContext,_ notaryArray: Array) -> Bool { 

    for index in 0...notaryArray.count - 1 
    { 
     let notary : Dictionary = notaryArray[index] as! Dictionary 
     let notaryFeeGrid = NSEntityDescription.insertNewObject(forEntityName: "NotaryFeeGrid", into: context) as! NotaryFeeGrid 

     notaryFeeGrid.id = notary["id"] 
     notaryFeeGrid.notaryLoansAmount = notary["notaryLoansAmount"] 
     notaryFeeGrid.notaryFeeAmount = notary["notaryFeeAmount"] 
    } 

    var error: NSError? 
    let success = context.save(&error) 
    if !success { 
     print("Save failed") 
    } 
}
