我正在尝试创建一个 ClockKit 复杂功能，它提供一个人的下一个班次开始时的数据，但是没有足够的时间线条目被生成或生成的频率不够高，所以有时，在一定时间后数据不准确。
我已经尝试调试并得出结论，只创建了 100 个时间线条目，适用于每个方向 1:40 小时的日期，对于我的应用程序来说还不够。我已经阅读了文档和延长时间线的方法，但发现它每天只能使用一定次数。
我包括print(String(limit) + " After")在我getTimelineEntries(complication:date:limit:handler)的查找它产生了多少。
我该怎么做才能让我的并发症从 00:00 延长到 23:59 的时间线？此外，为什么时间线不会在超过未来最接近的条目时自动延长？这似乎违背了苹果对并发症的意图。
我在下面包含了我的 ComplicationController.swift`。
