Hi, I am having a problem getting the VocalTextEdit app to save a document as per page 375. I have entered the code correctly but Xcode 9 (9A235) just produces screens and screens of error messages. I built it using Swift 4 and Swift 3.2 but it still doesn’t save.
Any suggestions would be gratefully received.
Thanks,
Stephen.
If you post some of those error messages and your code, you will increase the likelyhood that someone will be able to diagnose the problem.
PS: Always post your code properly formatted. If you don’t know how to do this, it is described in this post.
Here is the Swift 4 code of my Document class for saving the document
class Document: NSDocument {
enum Error: Swift.Error, LocalizedError {
case UTF8Encoding
var failureReason: String? {
switch self {
case .UTF8Encoding: return "File cannot be encoded in UTF-8."
}
}
}
override class var autosavesInPlace: Bool {
return true
}
override func makeWindowControllers() {
// Returns the Storyboard that contains your Document window.
let storyboard = NSStoryboard(name: NSStoryboard.Name("Main"), bundle: nil)
let windowController = storyboard.instantiateController(withIdentifier: NSStoryboard.SceneIdentifier("Document Window Controller")) as! NSWindowController
self.addWindowController(windowController)
}
override func data(ofType typeName: String) throws -> Data {
let windowController = windowControllers[0]
let viewController = windowController.contentViewController as! ViewController
let contents = viewController.textView.string ?? ""
guard let data = contents.data(using: .utf8) else {
throw Document.Error.UTF8Encoding
}
return data
}
override func read(from data: Data, ofType typeName: String) throws {
// Insert code here to read your document
// from the given data of the specified type...
throw NSError(domain: NSOSStatusErrorDomain, code: unimpErr, userInfo: nil)
}
}
and here are the error messages I am getting in Xcode

Can anyone help?
Thanks
From the error line above, it appears to me that your project may not have permissions to write into the user’s Documents folder. Take a look at the Capabilities panel for the project target then under “File Access” and insure that “Permissions & Access” is set to “Read & Write” for the “User Selected File”.
Hi BrianL3D1, thanks for that, it appears to be working now!
Stephen.
Hi,
You’re fix worked for me also. It’s a shame that this isn’t mentioned in this chapter, or at least not in the version I’m reading and following.
