Currently it's not working on Swift 4.0. It builds but whenever i try to choose date it crashes with the error below:

*** /Users/x/Desktop/x/x/x/EPCalendarPicker/EPCalendarPicker.swift:254:5: implicit Objective-C entrypoint -[x.EPCalendarPicker collectionView:layout:sizeForItemAtIndexPath:] is deprecated and will be removed in Swift 4; add explicit '@objc' to the declaration to emit the Objective-C entrypoint in Swift 4 and suppress this message 2017-09-14 09:26:27.702076+0300 x[1885:288332] *** /Users/x/Desktop/x/x/x/EPCalendarPicker/EPCalendarPicker.swift:254:5: implicit Objective-C entrypoint -[x.EPCalendarPicker collectionView:layout:sizeForItemAtIndexPath:] is deprecated and will be removed in Swift 4; add explicit '@objc' to the declaration to emit the Objective-C entrypoint in Swift 4 and suppress this message

I found the solution.

Step 1. Add this line in EPCalendarPicker.swift, Method : public init(startYear: Int, endYear: Int, multiSelection: Bool, selectedDates: [Date]?)

Lines To Add :
let rect = UIScreen.main.bounds
let screenWidth = rect.size.width - 7
layout.itemSize = CGSize(width: screenWidth/7, height: screenWidth/7)

Step 2 : Remove This Method :
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAtIndexPath indexPath: IndexPath) -> CGSize
{

    let rect = UIScreen.main.bounds
    let screenWidth = rect.size.width - 7
    return CGSize(width: screenWidth/7, height: screenWidth/7);
}

Add @objc in method to look like :

@objc func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, insetForSectionAtIndex section: Int) -> UIEdgeInsets
{
    return UIEdgeInsetsMake(5, 0, 5, 0); //top,left,bottom,right
}

Everything is working now.

To Show the Calendar call below method :

func showCalender() {
    
    let calendarPicker = EPCalendarPicker(startYear: 2017, endYear: 2099, multiSelection: false, selectedDates: [])
    calendarPicker.calendarDelegate = self
    calendarPicker.startDate = Date()
    calendarPicker.hightlightsToday = true
    calendarPicker.hideDaysFromOtherMonth = true
    calendarPicker.tintColor = UIColor.defaultAppColorDarkBlue
    //        calendarPicker.barTintColor = UIColor.greenColor()
    calendarPicker.dayDisabledTintColor = UIColor.lightGray
    calendarPicker.monthTitleColor = UIColor.black
    calendarPicker.todayTintColor = UIColor.clear
    
    //        calendarPicker.showsTodaysButton = false
    
    calendarPicker.weekendTintColor = UIColor.lightGray
    calendarPicker.weekdayTintColor = UIColor.darkGray
    
    calendarPicker.title = "DATE SELECT"
    calendarPicker.tintColor = UIColor.black
    
    calendarPicker.dateSelectionColor = UIColor.defaultAppColorDarkBlue
    
    let navigationController = UINavigationController(rootViewController: calendarPicker)
    //        self.present(navigationController, animated: true, completion: nil)
    self.present(navigationController, animated: true) {
        navigationController.updateFocusIfNeeded()
        self.view.setNeedsLayout()
    }
    
}
