Remove Parentheses () in URL string

Question

I have this string:

dataSourceURL = URL(string:"https://api.abc.com/api/p4/products?pid=uid8225&format=json&offset=\(count)&limit=20")

when I do print(dataSourceURL) I get:

How can I remove ()? Please suggest.

I want to get

https://api.abc.com/api/p4/products?pid=uid8225&format=json&offset=0&limit=20

@G S optional values need to be forced unwrap using optional Binding . — Tushar Sharma, Apr 15 '17 at 06:38
thanks El Captain v2.0, i have unwrapped it and it is working fine now , as mentioned i have declared as \(count!) and it is working fine , thanks a lot , much appreciated — Guri S, Apr 15 '17 at 06:43
@GS if count value is nil then please crash .. avoid forced unwrap — Nazmul Hasan, Apr 15 '17 at 06:44
Is it really necessary that the variable `count` is an optional? In almost all cases there is no reason to declare scalar types like `Int`, `Double`, `Bool` as optional. — vadian, Apr 15 '17 at 07:01

You can unwrap the value.

I would recommend using ?? as it will provide a default value and avoid the crash if it finds a nil.

let dataSourceURL = URL(string:"https://api.abc.com/api/p4/products?pid=uid8225&format=json&offset=\(count ?? 0)&limit=20")

it prints:

https://api.abc.com/api/p4/productspid=uid8225&format=json&offset=0&limit=20

Another way to do it is:

let dataSourceURL = URL(string:"https://api.abc.com/api/p4/products?pid=uid8225&format=json&offset=\(count!)&limit=20")

Be aware if count value is nil, the application will crash in this case.
