Hookah
DISCONTINUED. Hookah is a functional library for Swift. It's inspired by LoDash, Underscore project.
InfluxDB - Purpose built for real-time analytics at any scale.
* Code Quality Rankings and insights are calculated and provided by Lumnify.
They vary from L1 to L5 with "L5" being the highest.

What's included?
Importing Runes introduces several new operators and one global function that correspond to common Haskell typeclasses:
Functor
<^>(pronounced "map")
Applicative Functor
<*>(pronounced "apply")<*(pronounced "left sequence")*>(pronounced "right sequence")pure(pronounced "pure")
Alternative
<|>(pronounced "alternate")empty(pronounced "empty")
Monad
>>-(pronounced "flatMap") (left associative)-<<(pronounced "flatMap") (right associative)>->(pronounced "Monadic compose") (left associative)<-<(pronounced "Monadic compose") (right associative)
Implementations
We also include default implementations for Optional and Array with the following type signatures:
// Optional+Functor:
public func <^> <T, U>(f: T -> U, x: T?) -> U?
// Optional+Applicative:
public func <*> <T, U>(f: (T -> U)?, x: T?) -> U?
public func <* <T, U>(lhs: T?, rhs: U?) -> T?
public func *> <T, U>(lhs: T?, rhs: U?) -> U?
public func pure<T>(x: T) -> T?
// Optional+Alternative:
public func <|> <T>(lhs: T?, rhs: T?) -> T?
public func empty<T>() -> T?
// Optional+Monad:
public func >>- <T, U>(x: T?, f: T -> U?) -> U?
public func -<< <T, U>(f: T -> U?, x: T?) -> U?
public func >-> <T, U, V>(f: T -> U?, g: U -> V?) -> T -> V?
public func <-< <T, U, V>(f: U -> V?, g: T -> U?) -> T -> V?
// Array+Functor:
public func <^> <T, U>(f: T -> U, x: [T]) -> [U]
// Array+Applicative:
public func <*> <T, U>(fs: [T -> U], x: [T]) -> [U]
public func <* <T, U>(lhs: [T], rhs: [U]) -> [T]
public func *> <T, U>(lhs: [T], rhs: [U]) -> [U]
public func pure<T>(x: T) -> [T]
// Array+Alternative:
public func <|> <T>(lhs: [T], rhs: [T]) -> [T]
public func empty<T>() -> [T]
// Array+Monad:
public func >>- <T, U>(x: [T], f: T -> [U]) -> [U]
public func -<< <T, U>(f: T -> [U], x: [T]) -> [U]
public func >-> <T, U, V>(f: T -> [U], g: U -> [V]) -> T -> [V]
public func <-< <T, U, V>(f: U -> [V], g: T -> [U]) -> T -> [V]
// Result+Functor:
public func <^> <T, U, E>(f: (T) -> U, a: Result<T, E>) -> Result<U, E>
// Result+Applicative:
public func <*> <T, U, E>(f: Result<(T) -> U, E>, a: Result<T, E>) -> Result<U, E>
public func <* <T, U, E>(lhs: Result<T, E>, rhs: Result<U, E>) -> Result<T, E>
public func *> <T, U, E>(lhs: Result<T, E>, rhs: Result<U, E>) -> Result<U, E>
public func pure<T, E>(_ a: T) -> Result<T, E>
// Result+Alternative:
public func <|> <T, E>(lhs: Result<T, E>, rhs: @autoclosure () -> Result<T, E>) -> Result<T, E>
// Result+Monad:
public func >>- <T, U, E>(a: Result<T, E>, f: (T) -> Result<U, E>) -> Result<U, E>
public func -<< <T, U, E>(f: (T) -> Result<U, E>, a: Result<T, E>) -> Result<U, E>
public func >-> <T, U, V, E>(f: @escaping (T) -> Result<U, E>, g: @escaping (U) -> Result<V, E>) -> (T) -> Result<V, E>
public func <-< <T, U, V, E>(f: @escaping (U) -> Result<V, E>, g: @escaping (T) -> Result<U, E>) -> (T) -> Result<V, E>
