在通过修补代码重新创建JTAppleCalender时遇到问题

Question

我在尝试通过patchthecode的教程重新创建日历时遇到一些问题，这是链接：https://patchthecode.github.io/MainTutorial2/。 这是我遇到的一些错误：

1。无法将类型“ ViewController”的值分配给类型“ UICollectionViewDataSource？”

2。无法将类型“ ViewController”的值分配给类型“ UICollectionViewDelegate吗？”

3.'JTAppleCalendarView类型的值？没有成员'registerCellViewXib'

4.'JTAppleCalendarView类型的值？没有成员“ cellInset”

5。使用未声明的类型'DateCell'

6。'calendar（_：cellForItemAt：cellState：indexPath :)'的无效重新声明

7。使用未解析的标识符'myCustomCell'
