查找峰值元素（多个）SWIFT(Find peak elements (multiple) SWIFT)

 我将如何在数组中找到多个峰？ 
 
 给定数组：[1,2,3,4,5,4,3,2,3,4,5,6,5,4,3,2,4,2]我可以使用代码找到最大峰值下面。 
 
func findPeakElement(_ readings: [Int]) -> Int {
   if readings.count == 0 {
      return 0
   }

   while left < right {
      middle1 = (left + right) / 2
      middle2 = middle1 + 1
      if readings[middle1] < readings[middle2] {
         left = middle2
      } else {
         right = middle1
      }
   }         
   return left
}
 
 然而; 我需要找到所有的高峰; [5,6,4]我需要什么代码？ 即使它只是告诉我峰值的数量（3）就足够了。 

how would i find multiple peaks in an array?
 
given the array: [1,2,3,4,5,4,3,2,3,4,5,6,5,4,3,2,4,2] i can find the max peak using the code below.
 
func findPeakElement(_ readings: [Int]) -> Int {
   if readings.count == 0 {
      return 0
   }

   while left < right {
      middle1 = (left + right) / 2
      middle2 = middle1 + 1
      if readings[middle1] < readings[middle2] {
         left = middle2
      } else {
         right = middle1
      }
   }         
   return left
}
 
however; i need to find ALL the peaks ;[5,6,4] what code would i need for this? even if it just told me the number of peaks (3) it would be enough.
