Your dateFormat is not match with date. Try below code:

let date:String = "2018-08-04T07:34:15.287Z"
let dateFormatter = DateFormatter()
dateFormatter.timeZone = TimeZone.current
dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSZ"

dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSZ"
let dateToConvert = dateFormatter.date(from: date)

dateFormatter.dateFormat = "yyyy-MM-dd"
let finalDate = dateFormatter.string(from: dateToConvert!)

var dateFromString = Date()
if let aString = dateFormatter.date(from: finalDate) {
    dateFromString = aString
}

let timeInMiliseconds:Int = Int(TimeInterval(dateFromString.timeIntervalSince1970 * 1000))

You will get 1533321000000 in timeInMiliseconds
