Notes on On The Map

Playgrounds! Woot. Great to see. I wish they were a little more explanatory? Maybe set them up as a quick intro to someone new to iOS networking? or even yourself 6months from now when the details of talking to this api have become hazy?

Text Delegate: (you wrote)

// *** VERY IMPORTANT - to capture new user's input after a failed submission - user reenter a new value in textfield
// on UI -> DOES NOT MEAN that when they enter it, our code is going to register the NEW value! -> we must 
// call `shouldchangeCharactersIn` -> to REALLY "register" the NEW value!

This is actually a little bit backward… It’s not that we need to change the characters in the text field..It is instead the field asking us if it should allow the change. (as the text fields delegate [friend] it often asks us for advice about things)
Example: I recently used this method to not allow inserting more than 10 characters into a text field, but I wanted to allow deletion to happen no matter how many characters there were.
