Looking to assign inout array parameter to local var but getting error

Escaping closures can only capture inout parameters explicitly by value

Following is the code

func setData( feedsData:  inout [FeedStruct]) {
        DispatchQueue.main.async {
            self.arrData = feedsData // here is the error
    ....

You haven't shown enough code to understand why you are using `inout` but I strongly suggest you avoid `inout` parameters. As explained in the duplicate they are especially unsafe when combined with asynchronous execution. – Paulw11 Aug 23 '17 at 12:29
