Core data Can'；在Swift类之间传递核心数据对象

我有一组核心数据实体，可以成功地从Objective-C VC传递到Swift VC。我已经通过控制台确认他们来了

现在我需要遍历核心数据对象数组，并将它们传递到另一个swift vc。我已将阵列设置为属性（客户是CD实体）：

var arrcusters:Array=Customer

在我的循环中，我试图将它们传递给另一个Swift VC：

for thisCustomer in self.arrCustomers {

    let gridCell = storyboard.instantiateViewController(withIdentifier: "bulkAddCell") as! BulkAddCell
    resizeGridCell(vGridCell: gridCell.view, frameY: frameY, frameH:50.0)

    gridCell.thisCustomer = thisCustomer

    self.svData.addSubview(gridCell.view)
}

在BulkAddCell中，我将此客户作为一个属性：

var thisCustomer: Customer!

我知道BulkAddCell正在正确初始化，因为我在其中有一些IBOutlet，我可以在控制台中看到它们。但是这个客户总是零

我正在从Obj-C切换到Swift，所以我确信这是我所缺少的基本功能

更改：

var arrCustomers: Array = Customer

var arrCustomers = [Customer]() //init to an empty array of customer objects

//sometime later
//append your arrCustomers with instances of Customer

// before leaving first view controller access the arrCustomers object 
// contents as needed and assign to a corresponding property on the 
// destination view controller. (usually in preparforSegue)

至：

var arrCustomers: Array = Customer

var arrCustomers = [Customer]() //init to an empty array of customer objects

//sometime later
//append your arrCustomers with instances of Customer

// before leaving first view controller access the arrCustomers object 
// contents as needed and assign to a corresponding property on the 
// destination view controller. (usually in preparforSegue)

我已经按这种方式设置了它，但客户的值仍然为零，我也按照您所说的做了，在self.arrData{self.arrcusters.append（value as！customer）}中附加客户数组-->以获取值还可以在此处将Customer对象分配给目标控制器：gridCell.thisCustomer=thisCustomer我可以在self.arrcustomes中看到客户实体，它们永远不会被传递。
