Change the Font of UIAlertAction in Swift [duplicate]

Question

Now that iOS8 deprecated UIActionsheet and UIAlertview the customization working on iOS7 is not taking effect anymore. So far the only customization I'm aware is the tint color. And what I need is changing the title's font size and style which I haven't found any way of doing so with the new UIAlertAction.

Already referred to this but I'm still hoping there's a way to change at least the title size and font.

Providing you some of my code for UIAlertAction

UIAlertController * alertActionSheetController = [UIAlertController alertControllerWithTitle:@"Settings"
                                                                              message:@""
                                                                       preferredStyle:UIAlertControllerStyleActionSheet];
    UIAlertAction * aboutTheAppAction = [UIAlertAction actionWithTitle:@"About the App"
                                                                 style:UIAlertActionStyleDefault
                                                               handler:^(UIAlertAction * action){
                                                                   NSLog(@"About the app");
                                                                   [self openAbout];

                                                               }];


[alertActionSheetController addAction:aboutTheAppAction];
[self presentViewController:alertActionSheetController animated:YES completion:nil];

You can change UIAlertAction's Font and color. First you need to add UILabel Category

@interface UILabel (FontAppearance)
@property (nonatomic, copy) UIFont * appearanceFont UI_APPEARANCE_SELECTOR;
@end

@implementation UILabel (FontAppearance)

-(void)setAppearanceFont:(UIFont *)font {
    if (font)
        [self setFont:font];
}

-(UIFont *)appearanceFont {
    return self.font;
}

@end

Category File is also Uploaded on following URL https://www.dropbox.com/s/em91fh00fv3ut4h/Archive.zip?dl=0

After importing That file You need to call following function.

UILabel * appearanceLabel = [UILabel appearanceWhenContainedIn:UIAlertController.class, nil];
[appearanceLabel setAppearanceFont:yourDesireFont]]; 

Above code is tested on Color and font. and that will only valid for iOS8 or greater.
