Sample Solution:

Swift Code:

func make_array(_ a: [Int]) -> [Int] {
    var new_array: [Int] = []
    
    new_array.append(a[0])
    new_array.append(a.last!)
    
    return new_array
}

print(make_array([1, 2, 3]))
print(make_array([1, 2, 3, 4]))
print(make_array([10, 11, 12, -10]))

Sample Output:

[1, 3]
[1, 4]
[10, -10]
