Summary

Follows up #148 by checking every open issue against the modernized code and fixing the ones it did not cover. One commit.

Fixed here

• Range selection (Ability to select dates in range format #32). selectionMode with .single, .multiple and .range, selectRange(_:) and a didSelectRange delegate method. The first tap picks one end, the second selects every selectable day between them, in either order and across months; a third tap starts over and tapping a selected day clears the range. Days that canSelectDate refuses or that lie outside the data source are skipped. multipleSelectionEnable maps to the first two modes. The two cases the maintainer flagged on the 2018 attempt, ranges across months and re-selecting from the same day after a deselection, have tests. The SwiftUI wrapper gains selectionMode(_:).
• Per-day styles (can change background colour cell for specific date #136, How can I show only Sunday dates.. Remaining dates should be disabled .  #122). calendar(_:styleForDate:) on the delegate returns a Style for one day or nil for the calendar's own, so a holiday gets its own colour and days canSelectDate refuses can be greyed out. The SwiftUI wrapper gains styleForDate(_:).
• No data source (Code initialization problem #135). The view shows the current month instead of nothing, which is what the README always promised.
• Tests for Cell Font #117 and negative or zero item sizes are not supported in the flow layout #128. A style's cellFont reaches the cells; a frame shorter than the header neither asserts nor yields a zero item size.

Already fixed by #148, confirmed against the code

#100, #106, #108, #109, #110, #112, #114, #115, #120, #126, #127, #129, #130, #131, #132, #134, #138, #140, #142, #147.

Not library problems

#139 is a network timeout cloning from GitHub. #116 is a force-unwrapped outlet in the reporter's own view controller.

With this merged, every open issue is either fixed or outside the library's control.

Demo

The default tab greys out Sundays and colours the 15th through styleForDate; the SwiftUI tab has a single/multiple/range picker.

Test plan

• xcodebuild -scheme KDCalendar-Package -destination 'platform=iOS Simulator,name=iPhone 17 Pro,OS=26.5' test — 65 tests in 3 suites pass
• Example app runs on the iPhone 17 Pro (iOS 26.5) simulator, all three tabs, light and dark
• xcodebuild docbuild clean
• xcrun swift-format lint --strict --recursive Sources Tests Example/KDCalendarDemo clean
