Introduction<\/strong><\/h2>\n

We will assume that we want to have a JSON file added inside our project and want to access its data in swift language.<\/p>\n

Code<\/strong><\/h2>\n

You can create a JSON file in Xcode by going to File > New File > Empty<\/strong> and giving the file any name (eg. example.json). The file will be added and then we can add a JSON String in the file. i.e. –<\/p>\n

{“animal”:”Lion”, “bird”:”Sparrow”}<\/strong><\/p>\n

You can add the above-mentioned String directly into the JSON file that we created.<\/p>\n

The following function can be used to read the JSON data from the JSON file so that it can be accessed in Swift –<\/p>\n

  static func readJSONFromFile(fileName: String) -&gt; Any?\r\n    {\r\n        var json: Any?\r\n        if let path = Bundle.main.path(forResource: fileName, ofType: "json") {\r\n            do {\r\n                let fileUrl = URL(fileURLWithPath: path)\r\n                \/\/ Getting data from JSON file using the file URL\r\n                let data = try Data(contentsOf: fileUrl, options: .mappedIfSafe)\r\n                json = try? JSONSerialization.jsonObject(with: data)\r\n            } catch {\r\n                \/\/ Handle error here\r\n            }\r\n        }\r\n        return json\r\n    }\r\n\r\n<strong>Recommended Read: <\/strong><a href="https:\/\/www.knowband.com\/blog\/tutorials\/iterate-element-json-string-android-ios\/">Iterate through each element of JSON string in Android and iOS<\/a><\/pre>\n
