Fixed landscape mode for iphone 11

[chrischang]

Overview

• Description: While completing the layout challenge, I notices that the landscape on iphone 11 for the Tipsy-iOS13 was not displaying it correctly. I doubled checked by downloading the original repo again and realized that it was the case. This will work on iphone 11 / 8 since most students are probably taking the suggestion of using iphone 11 or 8.
• Note: Not really sure if it matters but thought that other students who are taking the course might be wondering, so I decided to send out this PR. Feel free to close this PR if you think it's not necessary.

P.S. Love the course :)
