How to Host app send data to app extension in IOS action extension

Question

i have done sample action extension app. am not able to get host app request data.i think is there some issue with this code.

Host App request code

  NSDictionary *request = @{@"username”:@“username”,@“password”:@“password”};
            UIActivityViewController *extensionController = [[UIActivityViewController alloc] initWithActivityItems:@[request] applicationActivities:nil];
           extensionController.popoverPresentationController.sourceView = self.view;
        [self presentViewController:extensionController animated:YES completion:nil];

App Extension code

NSExtensionItem *inputItem = self.extensionContext.inputItems[0];

    NSItemProvider *itemprovider = inputItem.attachments[0];

    [itemprovider loadItemForTypeIdentifier:(NSString *)kUTTypePropertyList options:nil completionHandler:^(NSDictionary *item, NSError *error) {

        NSDictionary *results = (NSDictionary *)item;

        NSLog(@“Host app Request Data=%@",results);

    }];

am not sure what's wrong above code, can anyone help me.. thanks

Turn on App Groups and use NSUserDefaults

1. Turn on App Groups and add group name in your both host target and extension target Capabilities

2. Input set data in host app source

    //use our group user defaults
    NSUserDefaults *defaults = [[NSUserDefaults alloc]  
    initWithSuiteName:@"group.com.organization.ProductName"];

    //set a greeting
    [defaults setObject:@"username" forKey:@"username"];
    [defaults setObject:@"password" forKey:@"password"];

    //synchronise
    [defaults synchronize];

3. SomeExtension.m

    //use our group user defaults
    NSUserDefaults *defaults = [[NSUserDefaults alloc] 
    initWithSuiteName:@"group.com.organization.ProductName"];

    //get the greeting    
    NSString *username = [defaults stringForKey:@"username"];
    NSString *password = [defaults stringForKey:@"password"];

    //check if greeting isn't empty
    NSLog(@"username = %@ / password = %@", username, password);
