how can we disable future dates and pass subtitle below date label in swift and how to use bridge header

Question

I have no idea how to use Objective-C in Swift file. I know how to create bridge header file but don't know how to to use it. https://github.com/WenchaoD/FSCalendar. I am using this pods. I want to disable future dates from today and pass a string to subtitle label in calendar. I want to implement this in Swift. I saw a Swift example on github.com but not worked Thanks is advance!

I've also tried this Disable future dates selection in FScalendar swift

if(!isAllowedToLimitFutureDates) 
{
    _maximumDate = [self.formatter dateFromString:@"2099-12-31"];
}
else
{
    _maximumDate = maxValidFutureDateAsString; // say "2017-03-13"
}

Just to make sure that I understood your case: you are using `FSCalendar` and you want to disable the highlight of the dates starting from tomorrow, correct? — Ahmad F, Apr 25 '18 at 07:54
yes that is correct @AhmadF and also want to pass a some string below date label that is in sub title. — Begineers, Apr 25 '18 at 08:18
These are multiple questions, so the viewer might getting confused about it. I can answer the disabling one :) You might want to separate them later... — Ahmad F, Apr 25 '18 at 08:20

In FSCalendar, you could set the maximum date to be selected by conforming to FSCalendarDataSource thus implementing:

maximumDate(for calendar: FSCalendar) -> Date

which tells the calendar view what is the maximum date that allowed to be highlighted. For instance:

Make sure that you are conforming to the delegate:

// conform to FSCalendarDelegate
class ViewController: UIViewController, FSCalendarDataSource {

    override func viewDidLoad() {
        super.viewDidLoad()

        // assign the delegate
        calendar.dataSource = self
    }
}

and then add into your view controller:

func maximumDate(for calendar: FSCalendar) -> Date {
    return Date()
}

which means the maximum date is today.

Output:

As you can see, you would be able to select any previous date but not more than today, date starting from tomorrow are grayed (dimmed and unselectable).

thank you but I get this error now Cannot load module 'fscalendar' as 'FSCalendar' not able to add delegate also – Begineers Apr 25 '18 at 09:08
@Begineers have you import it in the .swift file (`import FSCalendar`)? – Ahmad F Apr 25 '18 at 09:11
yes I import it then I got errro Cannot load module 'fscalendar' as 'FSCalendar' – Begineers Apr 25 '18 at 09:13
@Begineers it could be related to the bridging header. https://developer.apple.com/library/content/documentation/Swift/Conceptual/BuildingCocoaApps/MixandMatch.html – Ahmad F Apr 25 '18 at 09:14
I checked it can you please email me the your project created now at iosbeginners09@gmail.com I can verify it – Begineers Apr 25 '18 at 09:19
@Begineers there is something better than send it to your email, open terminal and run `pod try 'FSCalendar'` :) That's what I did, then I edited it. – Ahmad F Apr 25 '18 at 09:21
It is saying Updating spec repositories. one more thing have you imported anything in header file created is yes please let me know? – Begineers Apr 25 '18 at 09:26
@Begineers No, I didn't. After finishing "Updating spec repositories" it should give you 4 options to select your desired case... – Ahmad F Apr 25 '18 at 09:27
Tried but same error "Cannot load module 'fscalendar' as 'FSCalendar" when I import FSCalendar – Begineers Apr 25 '18 at 09:50
I got it but future date is not disabled I took uiview reference in file as calendar. class ViewController: UIViewController, FSCalendarDelegate{ @IBOutlet weak var calendar: FSCalendar! override func viewDidLoad() { super.viewDidLoad() calendar.delegate = self } func maximumDate(for calendar: FSCalendar) -> Date { return Date() } } what is calendar in your code is it uiview reference? – Begineers Apr 25 '18 at 10:17
@Begineers what's the version of Swift you are using? – Ahmad F Apr 25 '18 at 10:19
@DilipTiwari you could get it by implementing `didSelectDate` method from `FSCalendarDelegate`, it contains the selected date (as `Date`). – Ahmad F Apr 02 '19 at 09:30
@DilipTiwari I'd assume that it should work... Make sure that you are typing the correct signature for it (it could be it needs "_" before parameter names or something like this). – Ahmad F Apr 02 '19 at 09:35
func maximumDate(for calendar: FSCalendar) -> Date { return Date() } and set calendar.delegate = self in viewdidload its not working – Dilip Tiwari Apr 02 '19 at 09:37
@DilipTiwari `maximumDate` is for setting the maximum date for the calendar, `didSelectDate` is for selecting the date. What are aiming to achieve?! – Ahmad F Apr 02 '19 at 09:39
bro i want to disable future dates only that's why i tried this – Dilip Tiwari Apr 02 '19 at 09:40
and i have added two buttons above calendar when i click on Start date i have to select date and when i click on End date i have to select date then it will select all dates automatically between start and end date – Dilip Tiwari Apr 02 '19 at 09:42
