Composable TimeInterval extensions

TimeInterval.swift

extension TimeInterval {
    static func milliseconds(_ value: Self) -> Self {
        Self(value * 1e-3)
    }

    static func seconds(_ value: Self) -> Self {
        Self(value)
    }

    static func minutes(_ value: Self) -> Self {
        seconds(60) * value
    }

    static func hours(_ value: Self) -> Self {
        minutes(60) * value
    }

    func miliseconds(_ value: Self) -> Self {
        self + Self(value * 1e-3)
    }

    func seconds(_ value: Self) -> Self {
        self + Self(value)
    }

    func minutes(_ value: Self) -> Self {
        self + Self.seconds(60) * value
    }

    func hours(_ value: Self) -> Self {
        self + Self.minutes(60) * value
    }
}

Examples

UIView.animate(withDuration: .milliseconds(800)) {
    // animations
}

let t: TimeInterval = .hours(1).minutes(15).seconds(51)
print(t) // 4551
