A modified version of timeAgo. The native Apple one has bugs in iOS 12-13

timeago.swift

extension Date {
  func timeAgoSinceDate() -> String {
    // From Time
    let fromDate = self

    // To Time
    let toDate = Date()

    let time = Calendar.current.dateComponents([.month, .day, .hour, .minute, .second], from: fromDate, to: toDate)

    guard let months = time.month else { return "" }
    guard let days = time.day else { return "" }
    guard let hours = time.hour else { return "" }
    guard let minutes = time.minute else { return "" }
    guard let seconds = time.second else { return "" }

    if months > 0 {
        return "\(months)mo \(days)d"
    } else if days > 0 {
        return "\(days)d \(hours)h"
    } else if hours > 0 {
        return "\(hours)h \(minutes)m"
    } else if minutes > 0 {
        return "\(minutes)m \(seconds)s"
    } else {
        return "\(seconds)s"
    }
  }
