The Third ‘R’…

Lesson 10 of Module 4 of the iOS Foundations course from CodeWithChris covers the maths required for our Recipe App.

Pretty straightforward, but it’s nice to have a reminder. This one takes me back over 40 years to a time when we’d just moved to a new town, and I’d been doing Improper Fractions at my previous school for so long that they were second nature to me, but the new school had barely even begun on them.

I was quick to boredom in those days (much to the ire of many but, fortunately, the head master did his best to ensure my education didn’t go to waste).

( * the “third R” being ‘rithmetic, of course!)


Lesson 11 prepares the RecipeApp for the maths used when selecting a number of servings, bringing together a Picker() view together with a dynamically updated ingredient size in the recipe list.
