An abstract factory pattern is often used when a <strong>system must be independent of the way the objects<\/strong> it creates are produced.<\/p>\n<p>The abstract factory pattern is used to provide a client with a set of related objects, but without specifying their concrete classes. The client uses the abstract factory to create the objects, which are then used to accomplish some task.<\/p>\n<p>Here is an example of how to use the abstract factory pattern in Swift:<\/p>\n<pre class=\"brush: swift; title: ; notranslate\" title=\"\">protocol AbstractFactory {\r\n    func createProductA() -&gt; AbstractProductA\r\n    func createProductB() -&gt; AbstractProductB\r\n}\r\n\r\nprotocol AbstractProductA {\r\n    func operationA()\r\n}\r\n\r\nprotocol AbstractProductB {\r\n    func operationB()\r\n}\r\n\r\nclass ConcreteFactory1: AbstractFactory {\r\n    func createProductA() -&gt; AbstractProductA {\r\n        return ConcreteProductA1()\r\n    }\r\n\r\n    func createProductB() -&gt; AbstractProductB {\r\n        return ConcreteProductB1()\r\n    }\r\n}\r\n\r\nclass ConcreteProductA1: AbstractProductA {\r\n    func operationA() {\r\n        print(&quot;ConcreteProductA1 operationA&quot;)\r\n    }\r\n}\r\n\r\nclass ConcreteProductB1: AbstractProductB {\r\n    func operationB() {\r\n        print(&quot;ConcreteProductB1 operationB&quot;)\r\n    }\r\n}\r\n\r\n\/\/ Client\r\nlet factory = ConcreteFactory1()\r\nlet productA = factory.createProductA()\r\nproductA.operationA()\r\nlet productB = factory.createProductB()\r\nproductB.operationB()\r\n<\/pre>\n<p>In this example, the <strong>AbstractFactory<\/strong> protocol defines the interface for creating <strong>AbstractProductA<\/strong> and <strong>AbstractProductB<\/strong> objects. The <strong>ConcreteFactory1<\/strong> class is an implementation of the <strong>AbstractFactory<\/strong> protocol that creates concrete instances of <strong>ConcreteProductA1<\/strong> and <strong>ConcreteProductB1<\/strong> classes. The <strong>Client<\/strong> code uses the <strong>ConcreteFactory1<\/strong> to create <strong>AbstractProductA<\/strong> and <strong>AbstractProductB<\/strong> objects, and then calls their operations.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Abstract Factory Pattern is a creational design pattern that provides an protocol for creating families of related or dependent&#8230;<\/p>\n","protected":false},"author":1,"featured_media":3900,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_mi_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"jetpack_post_was_ever_published":false,"_jetpack_newsletter_access":"","footnotes":""},"categories":[1,160,232,155],"tags":[239],"aioseo_notices":[],"jetpack_featured_media_url":"https:\/\/i0.wp.com\/furkansandal.com\/wp-content\/uploads\/2022\/12\/abstract-factory-scaled.jpeg?fit=2560%2C1133&ssl=1","jetpack_sharing_enabled":true,"jetpack_shortlink":"https:\/\/wp.me\/p6BM7I-10T","amp_enabled":true,"_links":{"self":[{"href":"https:\/\/furkansandal.com\/wp-json\/wp\/v2\/posts\/3899"}],"collection":[{"href":"https:\/\/furkansandal.com\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/furkansandal.com\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/furkansandal.com\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/furkansandal.com\/wp-json\/wp\/v2\/comments?post=3899"}],"version-history":[{"count":1,"href":"https:\/\/furkansandal.com\/wp-json\/wp\/v2\/posts\/3899\/revisions"}],"predecessor-version":[{"id":3901,"href":"https:\/\/furkansandal.com\/wp-json\/wp\/v2\/posts\/3899\/revisions\/3901"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/furkansandal.com\/wp-json\/wp\/v2\/media\/3900"}],"wp:attachment":[{"href":"https:\/\/furkansandal.com\/wp-json\/wp\/v2\/media?parent=3899"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/furkansandal.com\/wp-json\/wp\/v2\/categories?post=3899"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/furkansandal.com\/wp-json\/wp\/v2\/tags?post=3899"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
