It was like this in swift2.3 in GitHub
" self.ListGroupname = tempList.sortedArrayUsingSelector(Selector("compare:")) "
and the system of swift 3.0 convert it to
" self.listGroupname = tempList.sortedArray(using: "compare:") "
while it gives a error message " sorted array produces [any] not the expected contextual result type "NSArray"
I have no idea what can I do. Can someone help?
It’s hard to be 100% sure what’s going on here without knowing the type of
self.listGroupname but, presuming they’re both NSArray, the issue is that
NSArray.sortedArray(using:) now returns
[Any], which is not directly assignable to NSArray. A quick fix would be to add an
self.listGroupname = tempList.sortedArray(using: #selector(NSString.compare(_:))) as NSArray
However, you’d be better off looking at your use of NSArray to see if you can make the jump to Swift arrays. They have a bunch of advantages, not least of which is the thorough type checking.
