code: VC

 if let timestamp = document.get("timestamp") as? TimeInterval {
     let date = Date(timeIntervalSince1970: timestamp)
     let dateFormatter = DateFormatter()
     dateFormatter.dateFormat = "yyyy/MM/dd HH:mm"
     let today = dateFormatter.string(from: date)
     print("Time Stamp's Current Time:(today)")
     let post = Post(email: email, caption: caption, imageUrl: imageURL, timestamp: timestamp)
...
...
...
...
cell.timeLabel.text = String(postArray[indexPath.row].timestamp)

code: Post

 struct Post {
    var email:String
    var caption:String
    var imageUrl:String
    var timestamp:Double

    init(email:String,caption:String,imageUrl:String,timestamp:Double) {
        self.email = email
        self.caption = caption
        self.imageUrl = imageUrl
        self.timestamp = timestamp
    }
}

    You have converted something from a network response into an Int. You have then called <int>.seconds. The error message is telling you that there is no such thing as .seconds on an Int.

    The timestamp that the Date class is expecting is simply a Double. You can use either the keyboard "Double" or "TimeInterval". Instead of casting as an Int, just do this:

    if let timestamp = document.get("timestamp") as? TimeInterval {
    let date = Date(timeIntervalSince1970: timestamp)

    Timestamp is just an int (number of seconds that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap seconds (in ISO 8601: 1970-01-01T00:00:00Z)).
    So doesn’t have a seconds property.
    Have you tried:
    let date = Date(timeIntervalSince1970: timestamp) ???
