Reading in a JSON File Using Swift

Reading in a JSON File Using Swift: A Quick Guide 📚✨

So you've been struggling with reading a JSON file into Swift, huh? Don't worry, we've all been there! But fret not, my friend, for I am here to guide you in the right direction. 🤓

The Problem 🧐

Our fellow coder Krivvenz has faced the same dilemma. After spending days searching and trying different methods, they still haven't been able to read their JSON file into Swift. The file, named test.json, contains a list of people with their respective details.

The Solution 💡

Well, Krivvenz, fear not because Swift has got your back! Here's how you can deserialize the JSON file and put it in an accessible Swift object:

1. Make sure you have your test.json file in the Documents directory.

   let file = "test.json" let dirs = NSSearchPathForDirectoriesInDomains(.documentDirectory, .allDomainsMask, true) guard let dir = dirs.first else { print("Oops! Directory not found.") return } let path = URL(fileURLWithPath: dir).appendingPathComponent(file)

2. Read the contents of the file as Data.

   do { let jsonData = try Data(contentsOf: path) } catch { print("Oops! Error reading JSON file.") return }

3. Deserialize the JSON data into a Swift object using JSONDecoder.

   let jsonDecoder = JSONDecoder() guard let jsonObject = try? jsonDecoder.decode([String: [Person]].self, from: jsonData) else { print("Oops! Error deserializing JSON data.") return }

4. Access your deserialized object!

   guard let people = jsonObject["person"] else { print("Oops! Error accessing the people array.") return } // Now you can play around with the people array as you please! 🎉 for person in people { print(person.name) print(person.age) print(person.employed) }

Conclusion 🎉

Voila! You've done it! You successfully read your JSON file into Swift and put it into an accessible object. 🙌🏼 Now you can play around with the data and do whatever you desire.
