Converting time from String to Date crashes on Simulator only

Question

Currently I am using this code to convert a time from String to Date:

public static func dateFromTime(_ time: String) -> Date {
    let formatter = DateFormatter()
    formatter.dateFormat = "k:mm"
    formatter.locale = NSLocale.current

    return formatter.date(from: time)!
}

This works on my device, but it crashes on the simulator. Both of them uses the 12 hour format from what I can see.

The string that this method receives when it crashes is "5:30 AM".

Any other reason why this code may crash on simulator and not device ?

Answer 1

Your code crashed because of proper date format !

For , "5:30 AM" use "h:mm a" , instead of "k:mm" .

To avoid any kind of crashes , update your code like below . .

public static func dateFromTime(_ time: String) -> Date {
        let formatter = DateFormatter()
        formatter.dateFormat = "h:mm a"
        formatter.locale = NSLocale.current
        if let date = formatter.date(from: time)
        {
            return date
        }
        print("Invalid arguments ! Returning Current Date . ")
        return Date()
    }
