A utility protocol for custom NSManagedObjects that makes querying contexts simpler and more convenient. Requires Swift 2.
import CoreData
protocol Fetchable
{
typealias FetchableType: NSManagedObject
static func entityName() -> String
static func objectsInContext(context: NSManagedObjectContext, predicate: NSPredicate?, sortedBy: String?, ascending: Bool) throws -> [FetchableType]
static func singleObjectInContext(context: NSManagedObjectContext, predicate: NSPredicate?, sortedBy: String?, ascending: Bool) throws -> FetchableType?
static func objectCountInContext(context: NSManagedObjectContext, predicate: NSPredicate?) -> Int

Thoughts on Swift 2 Errors

Thoughts on Swift 2 Errors

When Swift was first announced, I was gratified to see that one of the (few) philosophies that it shared with Objective-C was that exceptions should not be used for control flow, only for highlighting fatal programming errors at development time.

So it came as a surprise to me when Swift 2 brought (What appeared to be) traditional exception handling to the language.

Similarly surprised were the functional Swift programmers, who had put their faith in the Haskell-style approach to error handling, where every function returns an enum (or monad, if you like) containing either a valid result or an error. This seemed like a natural fit for Swift, so why did Apple instead opt for a solution originally designed for clumsy imperative languages?

I'm going to cover three things in this post:

class ArrayImpl<T> {
var space: Int
var count: Int
var ptr: UnsafeMutablePointer<T>
init(count: Int = 0, ptr: UnsafeMutablePointer<T> = nil) {
self.count = count
self.space = count

Declare on your main init that all other init methods should call. It's a nice additional semantic warning. Works with Xcode 5.1 and above. Not tested with earlier variants, but should just be ignored. A reference to this macro shortly appeared in https://developer.apple.com/library/ios/releasenotes/ObjectiveC/ModernizationObjC/AdoptingModernObj…
#ifndef NS_DESIGNATED_INITIALIZER
#if __has_attribute(objc_designated_initializer)
#define NS_DESIGNATED_INITIALIZER __attribute((objc_designated_initializer))
#else
#define NS_DESIGNATED_INITIALIZER
#endif
#endif

Liberal, Accurate Regex Pattern for Matching Web URLs
The regex patterns in this gist are intended only to match web URLs -- http,
https, and naked domains like "example.com". For a pattern that attempts to
match all URLs, regardless of protocol, see: https://gist.github.com/gruber/249502
