When working with URLComponents query items, it would be nice to write code like this:
var oqi: [URLQueryItem]? = [..., ..., ...] var comps = URLComponents(…) comps.queryItems += oqi The problem is that queryItems is [URLQueryItem]?, and so I can't just append. I'd like to write a version of += that: • Takes an LHS of [URLQueryItems]?, RHS of [things possibly derived from URLQueryItem]? • if LHS != nil, make an array of LHS, and optionally append RHS, and return that • if LHS == nil && RHS != nil, return RHS • If both are nil, return nil I'd like to do this in a generic way that works for any type on the left and possibly-dervied types on the right. -- Rick Mann rm...@latencyzero.com _______________________________________________ swift-users mailing list swift-users@swift.org https://lists.swift.org/mailman/listinfo/swift-users
