Answer 1

guard let callUrl = URL(string: "tel:0518858888"), UIApplication.shared.canOpenURL(callUrl) else {
    print("number is invalid")
    return
}

UIApplication.shared.open(callUrl, options: [:], completionHandler: nil)

Answer 2

just create a simple function

func makeCall(phoneNumber: String) {
    let formattedNumber = phoneNumber.components(separatedBy: NSCharacterSet.decimalDigits.inverted).joined(separator: "")
    let phonUrl = "tel://\(formattedNumber)"
    let url:NSURL = NSURL(string: phonUrl)!
    UIApplication.shared.open(url as URL)
}

call makeCall function from where you want

for you code just change

 URL(string: "tel://\(0518858888)") 

will work
