        let empURL = URL(string: "http://172.16.1.22/Get-Company-API/get-companies/")
        URLSession.shared.dataTask(with: empURL!) { (data, response, error) in
            do {
                if error == nil {
                    self.getCompanyArray = try JSONDecoder().decode([CompanyDataProfile].self, from: data!)

                    for mainArr in self.getCompanyArray {
                        DispatchQueue.main.async {
                            let companyDefaultValue = UserDefaults.standard
                            if let userID = companyDefaultValue.string(forKey: "user_type_id") {
                                self.getComData = self.getCompanyArray.filter { $0.company_id == userID }
                                print("Company ID Profile=\(userID)")
                                self.companyName_lbl.text = mainArr.company_name
                            }
                        }
                    }
                    print("****Employee Data****\(self.getCompanyArray)")
                }
            }
            catch {
                print("Error in get JSON Data Employee\(error)")
            }
            }.resume()
    }

Try this.

UserListObject

import UIKit

class UserListObject: NSObject {

    var strCompanyID: String    = ""
    var strFirstName: String    = ""
    var strLastName: String     = ""
    var strEmail: String        = ""

    class func parseFromDictionary(dict: NSDictionary) -> UserListObject {
        let objUser = UserListObject()

        if let company_id = dict["company_id"] as? String {
            objUser.strCompanyID = company_id
        }
        if let fname = dict["fname"] as? String {
            objUser.strFirstName = fname
        }
        if let lname = dict["lname"] as? String {
            objUser.strLastName = lname
        }
        if let email_id = dict["email_id"] as? String {
            objUser.strEmail = email_id
        }

        return objUser
    }
}

Your ViewController

Define this globally : var arrUsers = [UserListObject]()

so once you get data from API you can store it like below.

APIsManager.postCall(url!, params: _parameters, success: { (response) in
    //CommonHelper.hideProgress()
    let JSONData = response as! NSDictionary
    if(JSONData.object(forKey: "Success") as! Bool == true) {
        self.arrUsers.removeAll()
        let arrData = JSONData.value(forKey: "Data") as! NSArray

        for i in 0..<arrData.count {
            let dict = arrData.object(at: i) as! NSDictionary
            let objUser = UserListObject.parseFromDictionary(dict: dict)
            self.arrUsers.append(objUser)
        }
    }
    else {
        // Error
    }
}) { (response) in
    //Error
}

Once you get All users in arrUsers than you need to filter like Below.

let objLoggedInUser = self.arrUsers.filter{ $0. strCompanyID == YOUR_USERDEFAULT_ID}.first // THAT WILL RETURN YOU WHOLE OBJECT WITH ALL DETAILS

Now you can get values like.

self.lblFirstName.text = objLoggedInUser. strFirstName
self.lblLastName.text  = objLoggedInUser. strLastName
