Retry mechanism that retries a task a specified number of times before failing.

Answer:
```swift
func retry<T>(attempts: Int, task: @escaping () throws -> T) throws -> T {
    var attempt = 0
    while attempt < attempts {
        do {
            return try task()
        } catch {
            attempt += 1
        }
    }
    throw error
}
```

func retry<T>(attempts: Int, task: @escaping () throws -> T) throws -> T {
    for _ in 0..<attempts {
        do {
            return try task()
        } catch {
            continue
        }
    }
    throw error
}

Ensure the final output is produced by sequentially applying transformations starting from an initial value.

infix operator >>>: FunctionCompositionPrecedence

func >>> <T, U, V> (f: @escaping (T) -> U, g: @escaping (U) -> V) -> (T) -> V {
    return { x in g(f(x)) }
}

Question:
Write code in Swift programming language. Don't include usage examples or tests.
Custom infix operator >>> that composes two functions. The operator should take two functions and return a new function that represents the composition of the two functions (i.e., the output of the first function becomes the input of the second function).

Answer:
```swift
infix operator >>>: FunctionCompositionPrecedence

precedencegroup FunctionCompositionPrecedence {
    associativity: left
    higherThan: CastingPrecedence
}

func >>> <T, U, V> (f: @escaping (T) -> U, g: @escaping (U) -> V) -> (T) -> V {
    return { x in g(f(x)) }
}

Question:
Write code in Swift programming language. Don't include usage examples or tests.
Function that compares two version number strings (created with respect of semantic versioning specification including "alpha" and "beta" tags) and returning their ordering as a value of type ComparisonResult.

Answer:
```swift
enum ComparisonResult {
    case orderedSame
    case orderedAscending
    case orderedDescending
}

func compareVersions(_ lhs: String, _ rhs: String) -> ComparisonResult {
    let lhsComponents = lhs.components(separatedBy: ".")
    let rhsComponents = rhs.components(separatedBy: ".")
    
    for (index, lhsComponent) in lhsComponents.enumerated() {
        guard index < rhsComponents.count else {
            return.orderedDescending
        }
        
        let rhsComponent = rhsComponents[index]
        
        if let lhsNumber = Int(lhsComponent), let rhsNumber = Int(rhsComponent) {
            if lhsNumber < rhsNumber {
                return.orderedAscending
            } else if lhsNumber > rhsNumber {
                return.orderedDescending
            }
        } else {
            if lhsComponent < rhsComponent {
                return.orderedAscending
            } else if lhsComponent > rhsComponent {
                return.orderedDescending
            }
        }
    }
    
    return.orderedSame
}
```
