This code defines an `enum` called `ComparisonResult` to represent the three possible outcomes of a comparison: `orderedSame`, `orderedAscending`, and `orderedDescending`.
The `compareVersions` function takes two `String` parameters, `lhs` and `rhs`, representing the two version numbers to be compared. It first splits each version number string into an array of components using the `components(separatedBy:)` method.
Then, it iterates over the components of both version numbers using the `zip` function to compare each pair of corresponding components. If a pair of components is not equal, it returns the appropriate `ComparisonResult` based on their numerical values.
If all pairs of components are equal, it checks the length of the version number arrays. If one array is longer than the other, it returns the appropriate `ComparisonResult` based on their lengths.
If all pairs of components are equal and the length of the version number arrays is also equal, it returns `orderedSame`. // XCTAssertTrue failedenum ComparisonResult {

func compareVersions(_ lhs: String, _ rhs: String) -> ComparisonResult {
