You are doing the right way to get value of property. But you need to make sure myString has been assigned a value in init method of ViewController.

Try in ViewController.m:

- (instancetype)init {
    self = [super init];

    if (self) {
        self.myString = @"My String";
    }

    return self;
}

Beside of it, make sure that myMetod of SecondViewController is called. If myMetod is called, "Print value My String" will be printed.
