Adding query parameter to the GET url in iOS in Swift3

Question

I have an URL with

https://api.asiancar.com/api/applicationsettings

It is basically a GET url so I need to pass a boolean "isMobile" and timestamp as query parameters . How to achieve this as the ultimate URL after passing the query will look like this:

https://api.asiancar.com/api/applicationsettings?timestamp=111122244556789879&isMobile=true

let queryItems = [
    NSURLQueryItem(timestamp: "1234568878788998989", isMobile: true),
    NSURLQueryItem(timestamp: "1234568878788998989", isMobile: true)
]
let urlComps = NSURLComponents(string: "www.api.asiancar.com/api/applicationsettings")!
urlComps.queryItems = queryItems
let URL = urlComps.URL!

Am I doing right or any other modification ? please tell.

you can create String of url first and then use let URL = URL(string: "") to create final URL. — Akhilrajtr

even though the accepted answer will technically work, I strongly recommend you review my answer and continue to work with url components. They are more flexible and less prone to error once you become accustomed to them — JAB

Unless you have subclassed NSURLQueryItem, then your init method is not correct. Per Apple's documentation for NSURLQueryItem, the init method signature is:

init(name: String, value: String?)

This means your query items should be created like this:

let queryItems = [NSURLQueryItem(name: "timestamp" value: "1234568878788998989"), NSURLQueryItem(name: "isMobile", value: "true")]

This will properly add them to the url in the format you are expecting.

You can try an alternative way by using String

let baseUrlString = "https://api.asiancar.com/api/"
let timeStamp = 1234568878788998989
let isMobile = true
let settingsUrlString = "\(baseUrlString)applicationsettings?timestamp=\(timeStamp)&isMobile=\(isMobile)"
print(settingsUrlString)
let url = URL(string: settingsUrlString)

output : https://api.asiancar.com/api/applicationsettings?timestamp=1234568878788998989&isMobile=true

Try this :

let API_PREFIX = "www.api.asiancar.com/api/applicationsettings"

 var url : URL? = URL.init(string: API_PREFIX + queryItems(dictionary: [name: "isMobile", value: "true"] as [String : Any]))

func queryItems(dictionary: [String:Any]) -> String {
        var components = URLComponents()
        print(components.url!)
        components.queryItems = dictionary.map {
            URLQueryItem(name: $0, value: $1  as String)
        }
       return (components.url?.absoluteString)!
    }
