SwiftyCollection

Desription

This library provides an extension to the family of Collection protocols (Collection, MutableCollection, and RangeReplacableCollection) for easier and range-safe access to its elements. Most of the added functions return optionals where .none is returned instead of conventional fatal error.

Collection Methods

• func element(at index: Index) -> Element?
• func indexInBounds(_ index: Index) -> Bool

Mutable RangeReplaceableCollection Collection Methods

• mutating func removeLastSafe() -> SubSequence.Element?
• mutating func removeFirstSafe() -> SubSequence.Element?
• mutating func replaceOccurrences(with element: Element, where predicate: (Element) -> Bool)
• mutating func removeElement(where predicate: (Element) -> Bool) -> Self.Element?

Mutable RangeReplaceableCollection Collection Methods with Equatable Element

• mutating func replaceOccurrences(of element: Element, with newElement: Element)
• mutating func removeElement(element: Element) -> Self.Element?
• mutating func removeElement(at index: Self.Index) -> Self.Element?
• mutating func removeDuplicates()

RangeReplaceableCollection

The functions return a new collection

• func removingLast() -> Self
• func removingFirst() -> Self
• func removingElement(where predicate: (Element) -> Bool) -> Self
• func replacingOccurrences(with newElement: Element, where predicate: (Element) -> Bool) -> Self
• func replacing(with newElement: Element, at index: Self.Index) -> Self
• func removing(at index: Self.Index) -> Self

RangeReplaceableCollection with Equatable Element

• func removingElement(_ element: Element) -> Self
• func replacingOccurrences(of element: Element, with newElement: Element ) -> Self
• func removingDuplicates() -> Self
