Typed UITableView & UICollectionView Dequeuing in Swift
View UICollectionView+Registration.swift
import UIKit

/// The default implementation of `defaultIdentifier()` uses `NSStringFromClass(class)` rather than `String(class)` so that the module name is includded.
/// The hope being that this makes collisions unlikely making it unnnecessary to provide your own implementations.

tapi / error extension
Created Mar 27, 2015
Wouldn't this work instead of a nil default?
View error extension
extension NSError{
//...
class func
myParseError(description:String?="Parse failed.") -> NSError {
let info = [NSLocalizedDescriptionKey: description]
return self(
domain:myDomain,
code:MyErrorCodes.ParseError.rawValue,
userInfo:info)

tapi / GroupBy.swift
Created Feb 6, 2015
A generic groupby function that should work similarily to ruby's
View GroupBy.swift
/**
Group all items in a collection according to the value returned by a block.
:param: collection The collection whose items you want to group.
:param: groupBlock A block that returns a key for that value to be grouped by.
:returns: Returns a dictionary whose keys are the values returned by the groupBlock.
*/
func groupBy<V, K : protocol<Hashable, Equatable>, C : _ExtensibleCollectionType where C.Generator.Element == V>(collection: C, groupBlock: (V) -> K) -> [K: [V]] {
typealias ValueGroup = [V]
