NSURLSessionConfiguration.httpAdditonalHeaders
is declared to accept[AnyHashable:Any]
, but internally this maps to[String : String]
.Currently the code assumes that the
[AnyHashable:Any]
actually only containsNSString
s, whereas on macOS/Darwin its acceptable for eitherNSString
s orString
s to be used.I've therefore updated
URLSession._Configuration.convertToStringString()
to allow either and coerce to String if needed.
