Detect Jailbreak device iOS Swift/Objective-C

here is simple method to find jail breaking devices in swift.

Hopefully you checked on starting so put on starting view controller and call this function, if swift-

func DetectJailBreak() {   
 let url = URL(string: "cydia://package/com.example.package")
    if let url = url {
        if UIApplication.shared.canOpenURL(url) {
    let alert = UIAlertController(title: "Jailbroke Device found!!!", message: "This app can't be run in a Jailbroken device", preferredStyle: .alert)
    DispatchQueue.main.async(execute: { [self] in
        present(alert, animated: true)
    })
    return
    }
}

Objective -C

-(void)DetectJailBreak
{
        NSURL *url = [NSURL URLWithString:@"cydia://package/com.example.package"];
        if ([[UIApplication sharedApplication] canOpenURL:url]) {
            UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"Jailbroke Device found!!!" message:@"This app can't be run in a Jailbroken device"preferredStyle:UIAlertControllerStyleAlert];
            dispatch_async(dispatch_get_main_queue(), ^{
                [self presentViewController:alert animated:YES completion:nil];
            });
            return;
            }
}
