i'm new swift , have taken on project written in swift 2.2 xcode 7.4. converting xcode 8 , swift3 , have single compiler error left. please fix this. '[string : anyobject]' not convertible '[httpcookiepropertykey : any]' here offending line of code. let cookie = httpcookie(properties: dict as! [string : anyobject] as! [httpcookiepropertykey : any]) would fix it? let cookie = httpcookie(properties: dict as! [httpcookiepropertykey : any]) anyobject has been replaced any in swift 3 unspecified dictionary values. since httpcookiepropertykey type alias of (ns)string can cast type directly let cookie = httpcookie(properties: dict as! [httpcookiepropertykey : any]) maybe let cookie = httpcookie(properties: dict) could work.
