推荐答案

这在我的操场上对我有用。不确定它是最有效的方式，特别是对于大型字典，但它可能适用于你的情况。

This worked for me in a playground. Not sure it's the most efficient way, especially for a large dictionary, but it might work for your case.

var anyObjectDict = [String: AnyObject]()

anyObjectDict.updateValue("test", forKey: "key1") 
anyObjectDict.updateValue(1.0, forKey: "key2")

var anyDict = [String: Any]()

for key in anyObjectDict.keys {
    anyDict.updateValue(anyObjectDict[key], forKey: key)
}
