It's a little late in the evening and I wrote some Swift

lovely.swift

let numbers: Array<Int> = Array(1..<11)

enum IsOddError: Error {
    case noNumberProvided
    case throwForTheHeckOfIt
}

func isOdd(number n: Int?) throws -> Bool {
    if let value = n {
        if value == 10 { throw IsOddError.throwForTheHeckOfIt }
        return value % 2 == 1
    } else {
        throw IsOddError.noNumberProvided
    }
}

var isOdds: Array<Bool> = []
do {
    isOdds = try numbers.map({number in try isOdd(number: number)})
} catch IsOddError.noNumberProvided {
    print("This will never be reached")
} catch  {
    print("This threw for an unknown reason (\(error))")
}
print(isOdds)
