simple text editor in swift

To create a simple text editor in Swift, you can use a UITextView to display and edit text. Here are the steps:

1. Open Xcode and create a new project. Choose "Single View App" as the template.

2. In the storyboard, drag a UITextView onto the view controller's view. Adjust its size and position as desired.

3. In the view controller's code, create an IBOutlet for the text view:

main.swift
@IBOutlet weak var textView: UITextView!
41 chars
2 lines

4. Implement the save function. This function will save the text in the text view to a file. Here's some sample code:

main.swift
func save() {
    let fileManager = FileManager.default
    let documentsUrl = fileManager.urls(for: .documentDirectory, in: .userDomainMask).first!
    let fileUrl = documentsUrl.appendingPathComponent("myText.txt")
    do {
        try textView.text.write(to: fileUrl, atomically: true, encoding: .utf8)
    } catch {
        print(error)
    }
}
349 chars
11 lines

This code gets the URL for the app's documents directory, creates a file URL within that directory, writes the text in the text view to that file, and handles any errors that occur.

5. Connect the text view to the IBOutlet in the storyboard.

6. Add a button to the view controller's view. Connect it to an IBAction in the view controller's code. In the action, call the save function.

main.swift
@IBAction func saveButtonPressed(_ sender: UIButton) {
    save()
}
68 chars
4 lines

That's it! You now have a simple text editor that can save text to a file.
