Encode url string to Dictionary In my case: Some value have = inside

Question

I'm trying to convert decode to dictionary from the below url encoded string. The normal method of doing so is given below. In my case it is not working. Also i need to remove any character like \u{05}

let params = str.components(separatedBy: "&").map({
    $0.components(separatedBy: "=")
}).reduce(into: [String:String]()) { dict, pair in
    if pair.count == 2 {
        dict[pair[0]] = pair[1]
    }
}

My url encoded string is

"id=sfghsgh=sbfsfhj&name=awsjdk_fs\u{05}"

I'm expecting result as

{ 
"id" = "sfghsgh=sbfsfhj",
"name" = "awsjdk_fs"
}

How it is possible to achive?

Use URLComponents. See for example https://stackoverflow.com/a/55601459/1187415 — Martin R, May 23 '19 at 12:06
works fine. but when the key contains some unicode, the answer is falied, updated my question — Saranjith, May 23 '19 at 12:16
All characters are “Unicode characters.” What exactly do you want to remove? More details are needed. — Martin R, May 23 '19 at 12:19
Only `\u{05}`? What about `\u{04}` or `\u{10fff}`? Again: please describe the task *exactly,* otherwise we can only guess. — Martin R, May 23 '19 at 12:22
Your query string is not valid: `id` pair value has two `=`. That's why your `pair.count == 2` condition fails. — user28434'mstep, May 23 '19 at 12:38

Piggyback on URLComponents:

var components = URLComponents()
components.query = "id=sfghsgh=sbfsfhj&name=awsjdk_fs"

components.queryItems
// => Optional([id=sfghsgh=sbfsfhj, name=awsjdk_fs])

let list = components.queryItems?.map { ($0.name, $0.value) } ?? []
// [("id", Optional("sfghsgh=sbfsfhj")), ("name", Optional("awsjdk_fs"))]

let dict = Dictionary(list, uniquingKeysWith: { a, b in b })
// ["name": Optional("awsjdk_fs"), "id": Optional("sfghsgh=sbfsfhj")]

If you need a [String: String] rather than [String: String?]:

let list = components.queryItems?.compactMap { ($0.name, $0.value) as? (String, String) } ?? []
// [("id", "sfghsgh=sbfsfhj"), ("name", "awsjdk_fs")]

let dict = Dictionary(list, uniquingKeysWith: { a, b in b })
// ["name": "awsjdk_fs", "id": "sfghsgh=sbfsfhj"]
