Building collections from signals[-of-signals] of collection mutations
//
// A half-baked approach (not thread-safe, poor disposable management) for creating
// aggregate collections from multiple signals of collection mutations. In this
// case we are concating multiple mutation streams into a single container. So for
// each inner signal we need to offset subsequent splices by the count of preceding
// items (which can be recovered by scanning previous splices).
//
// Example:
//
// let (first, sink1) = SignalProducer<Splice<Int>, NoError>.buffer()

Want nullability right away? This will degrade gracefully until you can drop Xcode 6.1/Xcode 6.2.
// Xcode 6.3 defines new language features to declare nullability
#if __has_feature(nullability)
#define PSPDF_ASSUME_NONNULL_BEGIN _Pragma("clang assume_nonnull begin")
#define PSPDF_ASSUME_NONNULL_END _Pragma("clang assume_nonnull end")
#define ps_nullable nullable
#define ps_nonnull nonnull
#define ps_null_unspecified null_unspecified
#define ps_null_resettable null_resettable
#define __ps_nullable __nullable
#define __ps_nonnull __nonnull

A pragmatic and intentionally non-abstract solution to JSON decoding / initialization that doesn't require learning about five new operators.
struct User {
let id: Int
let name: String
let email: String?
}
extension User: JSONDecodable {
static func create(id: Int, name: String, email: String?) -> User {
return User(id: id, name: name, email: email)
}
