You can try

Swift

// force unwrapped to assure existence of data

let path = Bundle.main.path(forResource: "fileName", ofType: "plist")  

let dic = NSDictionary(contentsOfFile: path) as! [String:String]  

self.name = dic["username"] as! String

self.pass = dic["password"] as! String

when submit

check

if username.text == name && password.text == pass {
    // success
}

Objective-C

NSDictionary *mainDictionary = [NSDictionary dictionaryWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"fileName" ofType:@"plist"]];

NSString *name = mainDictionary[@"username"];

NSString *pass = mainDictionary[@"password"];

if ([username.text isEqualToString:name] && [password.text isEqualToString:pass]) {

     // success
}
