I am trying to migrate the next code from Objetive-C to Swift:
NSArray *voices = [AVSpeechSynthesisVoice speechVoices];
NSArray *languages = [voices valueForKey:@"language"];
NSLocale *currentLocale = [NSLocale autoupdatingCurrentLocale];
NSMutableDictionary *dictionary = [NSMutableDictionary dictionary];
for (NSString *code in languages)
{
dictionary[code] = [currentLocale displayNameForKey:NSLocaleIdentifier value:code];
}
And I did the following:
var voices:NSArray = AVSpeechSynthesisVoice.speechVoices()
var languages:NSArray=voices.valueForKey("language") as NSArray
var currentLocale:NSLocale=NSLocale.autoupdatingCurrentLocale()
var dictionary:NSMutableDictionary=NSMutableDictionary()
for code in languages {
var name=currentLocale.displayNameForKey(NSLocaleIdentifier, value: code)
dictionary[code]=name
}
and I am getting the following error:
error: type 'AnyObject' does not conform to protocol 'NSCopying' dictionary[code]=name
I don't know how to declare the dictionary object, to do something as simple as an array with country codes strings as key and a small description. like
dictionary[“es-ES"]=[“Spanish”] dictionary[“en-US"]=[“American English”]
NSDictionary
keys need to conform to NSCopying
, but AnyObject
doesn't necessarily. ( NSArray
returns AnyObject
s in Swift.) Use the as!
operator on your code
variable to be sure that it is:
dictionary[code as! NSCopying] = name
You can also downcast the language
array to [String]
and avoid the cast in the assignment code.
