Swift: Prompt Users to Review Your App

Urban Apps:

A simple yet powerful App Review Manager for iOS and OSX in Swift.

I like the idea behind Armchair:

Armchair prompts the user to write a review, but only after the developer knows they are satisfied. For example, you may only show the popup if the user has been using it for more than a week, and has done at least 5 significant events (the core functionality of your App).
