Sure, here is a Python solution for your problem:

```python
def swap_elements(arr):
if len(arr) == 0:
return arr
else:
arr[0], arr[-1] = arr[-1], arr[0]
return arr
```

This function `swap_elements` takes an array `arr` as input. If the array is empty (i.e., its length is 0), it returns the array as is. Otherwise, it swaps the first and last elements of the array using Python's multiple assignment feature, and then returns the modified array.
