XCode中线程的断点

Question

我没有定义断点，分别删除了所有现有的断点。尽管如此，它停止在一个特定的点，我不明白。它不在我的代码中。它在线程上更低级别？看截图。

我该如何避免这种情况？

附加信息/代码：

这似乎停留在 “LastselectedObject2” 的吸气

0x10b5a0efc <Prototypes.Timelineview.LastselectedObject2.getter : Prototypes.DisplayedObject+12>: movq 0x76215(%rip), %rax  ; direct field offset for Prototypes.Timelineview.LastselectedObject2 

它被迫与下面的代码：

println("touchesBegan at start . LastObject :" + self.timelineview.LastselectedObject2.sTitle); 

LastselectedObject2在timelineview类中定义：

class Timelineview: UIView { 

    var LastselectedObject2:DisplayedObject; 
... 
... 

的Class DisplayedObject看起来如下：

class DisplayedObject: NSObject, NSCopying { 

    var iType:Int = 0; // 0 = Phase ; 1 = Event 
    var X1:Int = 0; 
    var Y1:Int = 0; 
    var X2:Int = 0; 
    var Y2:Int = 0; 
    var sWikiID:String = ""; 
    var sTitle:String = ""; 
    var sImage:String = ""; 

    var bclickable:Bool = true; 

    func copyWithZone(zone: NSZone) -> AnyObject { 

     let a=DisplayedObject(iType: iType, X1: X1, Y1: Y1, X2: X2, Y2: Y2, sWikiID: sWikiID, sTitle: sTitle, sImage: sImage, bclickable: bclickable); 

     //let theCopy = self.dynamicType(iType: iType, X1: X1, Y1: Y1, X2: X2, Y2: Y2, sWikiID: sWikiID, sTitle: sTitle, sImage: sImage, bclickable: bclickable); 
     //theCopy.color = self.color 
     return a 

     //return DisplayedObject(); 
    } 

    override init(){ 
     //self.iType=iType; 
    } 

    init(iType:Int, X1:Int,Y1:Int,X2:Int,Y2:Int, sWikiID:String, sTitle:String, sImage:String, bclickable:Bool){ 
     self.iType=iType; 
     self.X1=X1; 
     self.Y1=Y1; 
     self.X2=X2; 
     self.Y2=Y2; 
     self.sWikiID=sWikiID; 
     self.sTitle=sTitle; 
     self.sImage=sImage; 
     self.bclickable=bclickable; 
    } 

    func empty(){ 
     X1 = 0; 
     iType = 0; // 0 = Phase ; 1 = Event 
     X1 = 0; 
     Y1 = 0; 
     X2 = 0; 
     Y2 = 0; 
     sWikiID = ""; 
     sTitle = ""; 
     sImage = ""; 
    } 
}

我曾与CoreData对象类似的问题，看到我的帖子：Swift: Breakpoint in CoreData Library

尽量使该类可见的ObjectiveC：

@objc(DisplayedObject) 
class DisplayedObject: NSObject, NSCopying { 
    ... 
}
