Created August 26, 2024 05:07 — forked from Edudjr/migrate-async-await-updated-extension.swift

	enum AsyncError: Error {
	case finishedWithoutValue
	}

	var cancellable: AnyCancellable?

tonyarnold / SwiftUIBackwardsCompatibleOnChange.swift

Last active April 16, 2021 06:20 — forked from jegnux/iOS13_onChange.swift

	import SwiftUI

	public struct ChangeObserver<V: Equatable>: ViewModifier {
	public init(newValue: V, action: @escaping (V) -> Void) {
	self.newValue = newValue
	self.newAction = action
	}

	private typealias Action = (V) -> Void

tonyarnold / Sequence+AnyCancellable.swift

Last active September 17, 2020 02:24

Useful extension for storing a sequence of AnyCancellable instances

	import Combine

	import Combine

	extension Sequence where Element == AnyCancellable {
	/// Stores this type-erasing cancellable collection in the specified collection.
	///
	/// - Parameter collection: The collection in which to store this ``AnyCancellable`` sequence.
	func store<C>(in collection: inout C) where C: RangeReplaceableCollection, C.Element == Element {
	forEach { $0.store(in: &collection) }

tonyarnold / NSObject+BidirectionalAssign.swift

Created September 11, 2020 05:52

Experiment to implement bidirectional assignment of values using Combine/KVO publishers

	import Combine
	import Foundation

	extension NSObjectProtocol where Self: NSObject {
	/// Assigns each unique element assigned to the key paths specified to the inverse object.
	func bidirectionallyAssign<Value: Equatable, B: NSObject>(
	from firstKeyPath: ReferenceWritableKeyPath<Self, Value>,
	to secondKeyPath: ReferenceWritableKeyPath<B, Value>,
	on otherObject: B
	) -> [AnyCancellable] {

tonyarnold / NSObject+AnyCancellable.swift

Created September 11, 2020 04:34

A nifty extension that I borrowed from DeclarativeHub's ReactiveKit: https://github.com/declarativehub/reactivekit/

	import Combine
	import ObjectiveC.runtime

	extension NSObject {
	private enum AssociatedKeys {
	static var CancellablesKey = "CancellablesKey"
	}

	/// A set that can be used to dispose of Combine cancellables.
	public var cancellables: Set<AnyCancellable> {

tonyarnold / RangeReplaceableCollectionOperators.swift

Created August 25, 2020 13:29

Use this to add an operator to append items to sequences, ie: `collection += item`

	extension RangeReplaceableCollection {
	static func += (collection: inout Self, element: Element) {
	collection.append(element)
	}

	static func += (collection: inout Self, element: Element?) {
	if let element = element {
	collection.append(element)
	}
	}

tonyarnold / EventLoopFuture+Helpers.swift

Created March 14, 2020 12:13

	import Vapor

	extension EventLoopFuture {
	/// When the current `EventLoopFuture<Value>` is fulfilled, run the provided callback,
	/// which will provide a new `EventLoopFuture`.
	///
	/// This allows you to dynamically dispatch new asynchronous tasks as phases in a
	/// longer series of processing steps. Note that you can use the results of the
	/// current `EventLoopFuture<Value>` when determining how to dispatch the next operation.
	///

tonyarnold / StringCoded.swift

Created February 12, 2020 08:16

	import Foundation

	@propertyWrapper
	struct StringCoded<WrappedValue: LosslessStringConvertible>: Codable {
	var wrappedValue: WrappedValue

	init(wrappedValue: WrappedValue) {
	self.wrappedValue = wrappedValue
	}
