Use nil-coalescing to replace a nil timestamp with some default value, e.g. a timestamp far far in the past:

let past = -TimeInterval.greatestFiniteMagnitude
self.array.sort(by: { 
     $0.event?.dateRecorded ?? past > $1.event?.dateRecorded ?? past
})

As mentioned above, there is no need to compare the timestamps to Date values, the numeric timestamps can be compared directly.
