func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {

    UIAlertController.initShow()
    
    return true
}

Objective-C

@import PRAlertFactory;

And just show somewhere in your UIView/NSObject based class.

Swift

import PRAlertFactory

class FooService: NSObject {
    public func fooRequest() -> Void {
        let alert: UIAlertController = UIAlertController(title:"Test title", message: "Test message", preferredStyle: .alert)
        let okAction: UIAlertAction = UIAlertAction(title: "OK", style: .default, handler: nil)
        alert.addAction(okAction)
        alert.show()
    }
}

Objective-C

#import "BarService.h"
#import <UIKit/UIKit.h>
#import <UIAlertControllerShowLegacy/UIAlertControllerShowLegacy-Swift.h>


@implementation BarService

- (void)barRequest {
    UIAlertController *alert =
    [UIAlertController alertControllerWithTitle:@"Test bar title"
                                        message:@"Test bar obj-c request"
                                 preferredStyle:UIAlertControllerStyleAlert];

    UIAlertAction *okAction = [UIAlertAction actionWithTitle:@"OK"
                                                       style:UIAlertActionStyleDefault
                                                     handler:nil];
    [alert addAction:okAction];

    [alert show];
}
