Alamofire GET request isn't working correctly - ios

Question

I am sending out a GET request like so.
let parameters: Parameters = [
"filter": ["fruit": "apple"]
]
Alamofire.request(urlStr, method: .get, parameters: parameters, encoding:URLEncoding.default).responseJSON { response in
print(response.request!)
}
However, the GET request doesn't work correctly. I believe the parameters are not correct at all. This is the URL request that is printed out using the following code print(response.request!)
https://api.example.com/fruits?apiKey=1&filter%5Bfruit%5D=apple
However, using postman I can send the correct request and get the correct response using the following URL request.
https://api.example.com/fruits?apiKey=1&filter={"fruit":"apple"}
I don't know how to fix this. I tried many encoding types, but none of it worked. Any tips or suggestions are appreciated
Edit: I do get a response from the server using alamofire, but it isn't correct data because the paramters are ignored. However, the response I get from postman is correct.

Morning Curt,
Since there is no published specification for how to encode collection types, the convention of appending [] to the key for array values (foo[]=1&foo[]=2), and appending the key surrounded by square brackets for nested dictionary values (foo[bar]=baz) [is used].
In my opinion you should really avoid passing array objects in query strings. You could change your request to something like:
apiKey=1&fruit=apple
Where does presence of field fruit itself indicates response should be filtered.
Moreover:
Instead of using GET, you should consider using POST or PUT and passing values via JSON, XML, or another well-defined format. This could require server side changes obviously.
If server side is out of your control, you should consider manually encoding these parameters instead.

You can find here an example of manually encoding.
Happy coding!
