In this chapter, you have learned to:

• Iterate through the Run-test-fix process to catch bugs

• Adapt the originally planned code to real hardware conditions, You have

• Enabled phone-to-watch communication using the WatchConnectivity framework

• Use of constants to make that communication easier to code safely

• You have also learned to create shared manager singletons

• Use NSUserDefaults to persistently store data on both devices

• You have used Interface Builder's Layout Constraints to create a minimalistic interface on the phone that will correctly adapt to all screen sizes and orientations
