这是一个问题。
第73行（TableView的CellForRowAt）将发生错误“索引超出范围”。但是，我认为价值观包含在``事件''中，但是为什么会这样？
此外，这是一个问题。我不能完全质疑逻辑。
我打算立即实施日历，并将FSCalendar用作库。简单的日历已完成，事件已注册为下一步（例如，事件⇨“县会议”，“开始日期”⇨“ 10月1日”，“结束日期”⇨“ 10月10日”）我想显示它在日历底部的UITableView中。
但是，我在编码之前不了解逻辑，并且遇到麻烦，因为即使我进行检查也不会出来。
数据库使用CloudFireStore，并且作为结构，
date_end：“ 2018年9月23日”，
date_start：“ 2018年9月27日”，
event_title：“高宝池比赛”，
scheduleID：“ 6F4YLHAcwZ3GuSS81sGK”，
time_end：“ 10：00”，
time_start：“ 16：00”，
已经成为。
我想告诉我是否存在可以突破的逻辑，或者数据库结构本身是错误的。另外，如果您不知道含义，我想告诉您。
