我有一个包含多个对象的Firebase资源,我想使用Swift迭代它们.我期望的工作如下(根据Firebase文档)
https://www.firebase.com/docs/ios-api/Classes/FDataSnapshot.html#//api/name/children

var ref = Firebase(url:MY_FIREBASE_URL)
ref.observeSingleEventOfType(.Value, withBlock: { snapshot in
  println(snapshot.childrenCount) // I got the expected number of items
    for rest in snapshot.children { //ERROR: "NSEnumerator" does not have a member named "Generator"
       println(rest.value)     
     }
 })

因此,似乎Swift迭代Firebase返回的NSEnumerator对象存在问题.

真的很受欢迎.
