The class must be a kind of AnyClass, so you can’t specify a struct type. Sorry I sent you off in the wrong direction on that. > The code I mentioned in my follow-up email seems to work: > > let array = decoder.decodeObject(of: [NSArray.self], forKey: kArrayKey) as! > [Int] That will compile, but might not work. If you’re doing *secure* decoding then the array of types must contain NSArray *and* the type of the elements in the array. However, if you’re not doing secure decoding (and I don’t think you’re required to, even if secure encoding was used to create the archive), then [NSArray.self] should work. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
