Method cannot be a member of an @objc protocol while using Dictionary

问题

I am coding in swift. I have written a protocol

@objc protocol ServerDelegate {
    optional func onDownloadDataComplete (downloadedData data : [Dictionary<String,Any>],result : ResultType,error : String)
}

First I received "Method cannot be a member of an @objc protocol because the type of the parameter 2 cannot be represented in Objective-C" for my enum but I fixed it by adding @objc. Now I am receiving this for Array of Dictionary. How to fix it?

回答1:

As @originaluser2 said Any cannot be represented in @objc so I created a new class, added data members which I needed, inherited it with NSObject and returned its array instead of dictionary and all is good now.
