Swift - open built-in iOS Dictionary to find word meaning

Question

In my project I\'d like to open iOS built-in Dictionary to find word meaning, or even better, get the meaning of the word directly in my app.

At the

Answer 1

I found the solution for Objective-C:

if ([UIReferenceLibraryViewController    dictionaryHasDefinitionForTerm:@"word"]) {
    UIReferenceLibraryViewController* ref = 
    [[UIReferenceLibraryViewController alloc] initWithTerm:@"word"];
    [currentViewController presentViewController:ref animated:YES completion:nil];
}

and I've edited it for Swift 3:

let word = "home"
if UIReferenceLibraryViewController.dictionaryHasDefinitionForTerm(word) {
        let ref: UIReferenceLibraryViewController = UIReferenceLibraryViewController(term: word)
        self.presentViewController(ref, animated: true, completion: nil)
}

and the same for Swift 4:

let word = "home"
if UIReferenceLibraryViewController.dictionaryHasDefinition(forTerm: word) {
    let ref: UIReferenceLibraryViewController = UIReferenceLibraryViewController(term: word)
    self.present(ref, animated: true, completion: nil)
}

This solution allows to open the built-in dictionary if the word has a definition in the dictionaries saved in the device

FYI: UIReferenceLibraryViewController.dictionaryHasDefinitionForTerm can't be used to display the result on your app. It seems those dictionary provider only authorized Apple to use their results, not any third party developer. Your app will be rejected:(

Try with this

func wordIsReal(word: String) -> Bool {
    let checker = UITextChecker()
    let range = NSMakeRange(0, count(word))
    let misspelledRange = checker.rangeOfMisspelledWordInString(word, range: range, startingAt: 0, wrap: false, language: "en_US")
    NSLog("misspelledRange:\(misspelledRange)")
    NSLog("word:\(word)")
    var arrGuessed:NSArray? = checker.guessesForWordRange(misspelledRange, inString: word, language: "en_US")as NSArray!
  NSLog("arrGuessed:\(arrGuessed)")
    //var correctedStr = textAsNSString.stringByReplacingCharactersInRange(misspelledRange, withString: arrGuessed.objectAtIndex(0) as String)
    return misspelledRange.location == NSNotFound
}
