将nil日期排序到数组的末尾 [英] Sorting nil Dates to the end of an Array

问题描述

尝试在Swift中按降序对数组进行排序.效果很好

Trying to sort an array in Swift in descending order. This works well

objectArray.sort{ $0.date!.compare($1.date!) == .orderedDescending}

如您所见，我强行解开日期.我正在寻找另一种方法，以便如果日期为nil，则对象将移动到数组的末尾.

As you can see, I'm force unwrapping the date. I'm looking for another way so that if the date is nil, the object moves to the end of array.

推荐答案

也许不是最干净的解决方案，但您可以通过零成本一步一步完成.

Maybe not the cleanest solution, but you can do it in one step with nil-coalescing.

objectArray.sort{ ($0.date ?? .distantPast) > ($1.date ?? .distantPast) }
