There is not enough information but I can guess you where you have made mistake. <\/p>\n

Your class Bookmark<\/code> is not singleton<\/strong> class so,every time Bookmark()<\/code> create new instance every time. that means it will create new bookmark<\/code> object for every instance.<\/p>\n

What I suggest you is inside func func setBookmark(imageURL:String, title:String, description:String, summary:String, date:String, link:String)<\/code><\/p>\n

Method 1 :<\/strong> Fetch the latest bookmarks in separate variable and append new object inside it and write to User Default as well as update the global object<\/p>\n

Method 2<\/strong> Or you can make it singleton and use shared instance for every time you perform operation.<\/p>\n

Method 3<\/strong> Another solution can be create global object of Bookmark<\/code> in AppDelegate<\/code> or Your singleton class and then use that object <\/p>\n

However <\/p>\n

func setBookmark(imageURL:String, title:String, description:String, summary:String, date:String, link:String)  {\n        bookmark.append([\"imageURL\":imageURL , \"title\":title , \"description\":description, \"summary\":summary , \"date\":date, \"link\":link])\n        UserDefaults.standard.set(bookmark, forKey: \"bookmark\")\n\n  }\n<\/code><\/pre>\n
This is the bad practice to follow.  You are directly replacing<\/strong> User default with new value however your intension is to append new element not replace existing data in userdefault. <\/p>\n
You should always fetch latest and update it Like method 1 show as well as If you wanted to fetch the data in userdefault there is no use of your global object      var bookmark: [[String:Any]] = []<\/code> because you have already getBookrmark<\/code> method there <\/p>\n
Hope it is clear to you<\/p>\n<\/p><\/div>\n
