I have this array
var bookTimeArray = [BookTime]()
BookTime class contains followings
var time : String = ""
var status : String = ""
var booked_by : String = ""
Now i need to sort the array bookTimeArray by seeing the BookTime.time variable.
Time variable may contain one time from "12AM" to "11PM"
The object need to be sorted in following pattern
["12AM", "1AM", "2AM", "3AM", "4AM", "5AM", "6AM", "7AM", "8AM", "9AM", "10AM", "11AM", "12PM", "1PM", "2PM", "3PM", "4PM", "5PM", "6PM", "7PM", "8PM", "9PM","10PM", "11PM"]
if bookTimeArray has 5 object
bookTimeArray[0].time = "10AM"
bookTimeArray[1].time = "6AM"
bookTimeArray[2].time = "9AM"
bookTimeArray[3].time = "6PM"
bookTimeArray[4].time = "9PM"
Expected output
bookTimeArray[0].time = "6AM"
bookTimeArray[1].time = "9AM"
bookTimeArray[2].time = "10AM"
bookTimeArray[3].time = "6PM"
bookTimeArray[4].time = "9PM"
I cant figure out how to achieve this. Help me out :(
You can do it this way:
// First create a DateFormatter object to convert your time strings to Date objects so you can compare between them.
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "ha"
dateFormatter.locale = Locale(identifier: "en_US_POSIX")
// Then you only need to sort the bookTimeArray by *time* property after converting *time* string to a Date object using the dateFormatter that we've created above.
let sortedBooks = bookTimeArray.sorted { dateFormatter.date(from: $0.time)! < dateFormatter.date(from: $1.time)! }
You can use dateFormatter for creating Date objects from your String property and then you can sort your array by these Dates
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "ha" // format 1AM, 2AM, 12PM, ...
dateFormatter.locale = Locale(identifier: "en_US_POSIX")
Sorting:
bookTimeArray.sort { bookTime1, bookTime2 in
guard let date1 = dateFormatter.date(from: bookTime1.time), let date2 = dateFormatter.date(from: bookTime2.time) else { return false }
return date1 < date2
}
Hope this will help:
// Custom models array
let dataArray = [Class(fileID:1),Class(fileID:2),Class(fileID:3)]
// here is sorting code
dataArray.sorted({ $0.fileID > $1.fileID })

When I am running the code below the date and time returned are in correct format but just not from what's coming from the API which in this case is the currentVehicle.LastCommunicationDate!
Instead of coming the time from the currentVehicle.LastCommunicationDate! it's just returning a random timezone I think that is getting from the Server or something like that.
The output of the code I have right now is: 2022-01-21 02:04:15 when it should have been the live time in my local timezone but it's getting a different timezone.
The LastCommunicationDate coming from postman is in json format: "LastCommunicationDate": "2022-01-21T10:58:21.367",
The time i want to be is the one from Postman just converted from json to normal time like: yyyy-MM-dd HH:mm:ss
let timeinterval : TimeInterval = (currentVechicle.LastCommunicationDate! as NSString).doubleValue
let dateFromServer = NSDate(timeIntervalSinceNow:timeinterval)
let outFormatter = DateFormatter()
outFormatter.locale = Locale(identifier: "en_Al")
print(dateFromServer)
let dateFormater = outFormatter
outFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
print(dateFormater.string(from: dateFromServer as Date))
let dateFromServers = dateFormater.string(from: dateFromServer as Date)
LastCommunicationDate is a string, but you are converting it to a Double. Try this instead:
let lastCommunicationDate = "2022-01-21T10:58:21.367"
//Create dateformatter to convert string to Date
let isoDateFormatter = ISO8601DateFormatter()
isoDateFormatter.formatOptions = [
.withFullDate,
.withTime,
.withColonSeparatorInTime,
.withFractionalSeconds
]
let isoDateFormatter2 = ISO8601DateFormatter()
isoDateFormatter2.formatOptions = [
.withFullDate,
.withTime,
.withColonSeparatorInTime
]
let date = isoDateFormatter.date(from: lastCommunicationDate) ?? isoDateFormatter2.date(from: lastCommunicationDate)
//Create dateformatter to format date for output
let outFormatter = DateFormatter()
outFormatter.locale = Locale(identifier: "en_Al")
outFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
let dateFromServers = outFormatter.string(from: date!)
I have separated date and time according to my code, then I have used DateFormatter but date not coming correctly.. why?
coming like this: Optional("08/15/0020")
var formateFromdate: String?
var formateTodate: String?
func addDate(){
var fromDateArr = fromDateLabel.text!.components(separatedBy: ",")
fromDate = fromDateArr[0]
fromTime = fromDateArr[1].replacingOccurrences(of: " ", with: "")
var toDateArr = toDateLabel.text!.components(separatedBy: ",")
toDate = toDateArr[0]
toTime = toDateArr[1].replacingOccurrences(of: " ", with: "")
let inputFormatter = DateFormatter()
inputFormatter.dateFormat = "MM/dd/yyyy"
let showDateFrom = inputFormatter.date(from: fromDate)
inputFormatter.dateFormat = "MM/dd/yyyy"
formateFromdate = inputFormatter.string(from: showDateFrom!)
print(formateFromdate)
}
note: here fromDate = 08/15/2020 coming correct but after formate date not coming correct
OutPut:
Optional("08/15/0020") it should be 08/15/2020
From the formatted date output, it seems the value of fromDate = fromDateArr[0] is "08/15/20" If that's the case, you will have to use a date format as below;
let inputFormatter = DateFormatter()
inputFormatter.dateFormat = "MM/dd/yy"
let showDateFrom = inputFormatter.date(from: fromDate)
inputFormatter.dateFormat = "MM/dd/yyyy"
let formateFromdate = inputFormatter.string(from: showDateFrom!)
print(formateFromdate)
You need to unwrap it first
if let formate = inputFormatter.string(from: showDateFrom!){
print(formate)
}
I would like to format my dates to not have zeros in the beginning.
For example
04/03/20 -> swift should display as 4/3/20
I basically want to remove the zero that may be in front of the day, month, or year. The purpose of this is not for style purposes but for me to access data in a JSON. That's why it needs to be soo specific.
You can get by using Date & DateFormatter
let formatter = DateFormatter()
formatter.dateFormat = "dd/MM/yy" // change formate as per your requirement
let date = formatter.date(from: "04/03/20") //change "04/03/20" to your input string
formatter.dateFormat = "d/M/yy"
let dateString = formatter.string(from: date!)
print(dateString) // 4/3/20
let date = "04/03/20"
let parts = date.split(separator: "/")
var newDate = ""
for i in 0..<parts.count {
newDate = "\(newDate)\(i == 0 ? "" :"/")\(Int(parts[i])!)"
}
print(newDate) //Result - 4/3/20
How would I be able to take the date format from a URL and turn It into 2 separate date values in SwiftUI. The format from JSON is 2019-11-06 18:30:00 and I'm trying to get it to show as Dec 5 and would also like it to separate the time and show 8:00PM, is this possible?
This is the code that references the start time:
let startTime: String
var startTime: String {
return self.post.startTime
}
Let's step around the fact that 2019-11-06 18:30:00 can't be represented as Dec 5 and 8:00PM and focus on the work flow you'd need.
The basic idea is to:
Convert the String to a Date, via a DateFormatter
Use a custom DateFormatter to format the Date to the required "date" value
Use a custom DateFormatter to format the Date to the required "time" value
This might look something like...
let startTime = "2019-11-06 18:30:00"
let formatter = DateFormatter()
formatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
if let date = formatter.date(from: startTime) {
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "MMM d"
let dateString = dateFormatter.string(from: date)
let timeFormatter = DateFormatter()
timeFormatter.dateFormat = "h:ma"
let timeString = timeFormatter.string(from: date)
} else {
print("Bad date/format")
}
In my testing, this outputs Nov 6 and 6:30PM
you can pass your string date to date with this function
func stringToDate(date: String, format: String) -> Date
{
let date2 = date.count == 0 ? getCurrentDate(format: "dd-MM-yyyy") : date
let dateFormatter = DateFormatter()
dateFormatter.timeZone = TimeZone.init(identifier: "América/Mexico_City")
dateFormatter.dateFormat = format
let dateDate = dateFormatter.date(from: date2)
return dateDate!
}
func getCurrentDate(format: String) -> String
{
let formD = DateFormatter()
formD.dateFormat = format
let str = formD.string(from:Date())
return str
}
let dateA = stringToDate(date: "2019-11-06 18:30:00", format: "yyyy-MM-dd HH:mm:ss")
if dateA < Date() //Date() always will be the current date, including the time
{
print("dateA is older")
}
else
{
print("dateA in newer")
}
play with the format examples formats
Basically i have a tableView where i save a date... then i want to save another date, and push the first date from '0' in array to '1' position, while populating '0' with new date
let now = Date()
var date = ""
This creates a date ^^
var list = [ String(date) ]
this is the array ^^
let dateFormatter = DateFormatter()
dateFormatter.dateStyle = .short
dateFormatter.timeStyle = .short
// print(dateFormatter.string(from: now))
date = (dateFormatter.string(from: now))
This turns raw date into an easy to read string ^^
I want to make a function that Saves that string in the array, moves it down and creates a new one with new date
You can declare the array of date strings like this
var dates = [String]()
then create the date string
let now = Date()
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "MMM dd,yyyy"
let dateStr = dateFormatter.string(from: now)
then insert it in the array at index 0
dates.insert(dateStr, at: 0)
