    if i != pos {

Maybe this code will help.

It deletes item with a given index.

Takes the array, and the index to delete and returns a new array pretty much like append function.

func deleteItem(arr []int, index int) []int{
  if index < 0 || index >= len(arr){
    return []int{-1}
  }

    for i := index; i < len(arr) -1; i++{
      arr[i] = arr[i + 1]

    }

    return arr[:len(arr)-1]
}
