ios - Could not cast value of type 'Swift.Array<Swift.String>' (0x61000028bb50) to 'Swift.String' (0x10cbd0ae0) -

i have program initial search of users populates table. there 2 buttons within table accept users request , deny, these buttons call insert function inputs results in database. array results being passed function i'm getting error of 'could not cast value of type 'swift.array' (0x61000028bb50) 'swift.string' (0x10cbd0ae0)' on following line of code:

    self.insertshot("no", (gname as? string anyobject)) 

the gname variable declared follows:
var gname = string

here code getting array data:

    in 0 ..< self.guest.count {      let ava = self.guest[i]["ava"] as? string      let gname = self.guest[i]["username"] as? string     let city = self.guest[i]["city"] as? string     let state = self.guest[i]["state"] as? string     let url = nsurl(string: ava!)!      self.avas.append(image)     self.gname.append((gname anyobject) as! string)     self.tableview.reloaddata() 

insertshot function

public func insertshot(_ rating : string,_ gname : anyobject) {     // shortcuts data passed php file      let reviewer = user?["username"] as! string     print("print 3", gname)              // url path php file     let url = url(string: "http://www.xxxxx.com/xxxxx.php")!     var request = urlrequest(url: url)     request.httpmethod = "post"      // param passed php file     let param = [         "user" : reviewer,         "revieweduser" : gname,         "rating" : rating     ] [string : any]      // body     let boundary = "boundary-\(uuid().uuidstring)"     request.setvalue("multipart/form-data; boundary=\(boundary)", forhttpheaderfield: "content-type")      // ... body     request.httpbody = createbodywithparams(param as?

the following functions used when yes or no buttons selected , call insertshots function:

@ibaction func nobtn_clicked(_ sender: uibutton) {     print("print 6", gname)     self.insertshot("no", (gname as? string anyobject))     //dosearch("")  } @ibaction func yesbtn_clicked(_ sender: uibutton, users: anyobject) {      self.insertshot("yes", (gname as? string anyobject))  } 

it seems may inadvertently passing array self.gname instead of simple string. context have, can't tell if you're trying pass in array or string. code making use of "no type" types, such any , anyobject. explicitly disabling safety , helpfulness of swift type system.

i'd recommend changing function declaration indicate need. such as:

public func insertshot(_ rating: string, _ gname: string) 

then within body, can change dictionary declaration to

let param = [     "user" : reviewer,     "revieweduser" : gname,     "rating" : rating ] 

then drop cast:

request.httpbody = createbodywithparams(param, boundary: boundary) 

you passing in self.gname array of strings. need pass in string.

change this: if let gnamestring = self.gname.first { self.insertshot("yes", gnamestring) }

note: code creating array, presumably need figure out which value in array want pass in.
