Newsletter #1 - Objective-C and Swift Interoperability and Mach-O executables Sep 20 2019

Hello,

Another week has gone by trying to figure out how computers work under the hood, and also enjoying dark mode on iOS. I hope you are enjoying the update too. Everything went smooth on the update, the only problem I had was with my reminders.

I make heavy use of reminders, both on my phone and on my laptop. So you can imagine, I was all excited tapping yes to every new popup on my phone. And I didn’t pay attention to the warning for Reminders. If you update to the new reminders, you won’t be able to see them in macOS until you upgrade to Catalina. My advice, make sure you won’t be needing your reminders on macOS before tapping “upgrade”.
