Using dynamicType total result in EXC_BAD_ACCESS

The following code works fine in iOS Simulator, but throws an EXC_BAD_ACCESS exception on the device.

Is this a bug in Swift or am I just doing something weird here?

What does not work:

class Foo: NSObject {
    class var name: String {
        return "A foo"
    }
}

struct FooWrapper<T: Foo> {
    var fooName: String

    init(foo: T) {
        fooName = foo.dynamicType.name
    }
}

var foo = Foo()
var fooWrapper = FooWrapper(foo: foo)
println(fooWrapper.fooName)

      

        
        
        
      

    

To make it work:

• Use (foo as Foo).dynamicType.name
  
  
• Or remove NSObject as superclass Foo
