I am using the modalVC to set/change parameters for a calculation. These parameters are properties of the presentingVC, which also has a 'Start Calculation' button. So when I open the modalVC, the textfields need to show the current values of the parameters. When I close it, the values need to go back to the properties of the presentingVC. So using the completion block to pass these values around seemed like a good idea.
