Swift Encoding a JSON dictionary [String: Any], can't get rid of the quotes

We are grabbing some data from an API, which we decode into a [String: Any] dictionary.
We want to then take this dictionary, and mutate a value for a key "$twitter_card". Then we want to encode that back into Data, which we send back to the API.

if let dict = try? JSONSerialization.jsonObject(with: data, options: []) as? [String: Any], var dataDict = dict["data"] as? [String: Any] {

    let summary: Any = "summary"
    print(dataDict)
    dataDict["$twitter_card"] = summary
    print(dataDict)


    let url = URL(string: "https://api2.branch.io/v1/url?url=(link)")!
    var request = URLRequest(url: url)
    request.httpMethod = "PUT"

    let jsonData = try? JSONSerialization.data(withJSONObject: ["branch_key": EnvConstants.branchKey, "branch_secret": EnvConstants.branchSecretKey, "data": dataDict])
    request.httpBody = jsonData

Print statement before setting "$twitter_card":

["~feature": TwitterShare, "$publicly_indexable": 1, "$one_time_use": 0, "~id": 881331908143151724, "~creation_source": 3, "~channel": twitter, "$og_description": HELLO WORLD, "$twitter_app_country": US, "$twitter_card": summary_large_image]

After setting "$twitter_card":

["~feature": TwitterShare, "$publicly_indexable": 1, "$one_time_use": 0, "~id": 881331908143151724, "~creation_source": 3, "~channel": twitter, "$og_description": HELLO WORLD, "$twitter_app_country": US, "$twitter_card": "summary"]

Notice how before there aren't quotes in the value, but after there is. We believe the API request is failing because of this, but can't figure out how to match the same data type on the request back.
