我在swift和Xcode 6中编写这段代码

@IBAction func Alert(sender : UIButton) {
  var alert : UIAlertView = UIAlertView(title: "Hey", message: "This is  one Alert",       delegate: nil, cancelButtonTitle: "Working!!")

    alert.show()
}

Xcode在编译时不显示错误.

但在模拟器中,APP失败并返回错误:

(lldb)
thread 1 EXC_BAD_ACCESS(code 1 address=0x20)

这段代码:

class InterfaceController:WKInterfaceController {

@IBOutlet weak var petTable: WKInterfaceTable!

var petnames = ["Luna", "dylan", "Mery", "Mady", "Paul Newman", "heidi"]

override init(context: AnyObject?) {
    // Initialize variables here.
    super.init(context: context)

返回两个错误:"初始化程序不会覆盖行覆盖中的超类指定的初始化程序"

"必须在super.init行中调用超类'WKInterfaceController'的指定初始化程序

错误发生在Xcode 6.2 beta 2(今天发布)

在以前版本的Xcode中没有显示错误
