DAY 90


Now that the end of the 100 days challenge is finally in sight, I hope you’re finding second wind to press ahead through these last few days. As John Quincy Adams once said, “patience and perseverance have a magical effect before which difficulties disappear and obstacles vanish.”

You’ve definitely shown lots of patience and perseverance because you’ve made it this far, and with just a little more effort you’ll make it to the end. To give you a little boost, this is the first of two consolidation days, both of which will give you lots of fun practice with Core Graphics – you’ll get lots of practice, and perhaps even learn a couple of new things along the way!

Today you have three topics to work through, one of which of is your challenge.

Note: Don’t worry if you don’t complete challenges in the day they were assigned – in future days you’ll find you have some time to spare here and there, so challenges are something you can return back to in the future.
