Swiftoberfest is over for this year! 62 new articles from me (and over a dozen reader submissions) should give you lots of reading as the nights grow longer. Next stop: Swiftmas!
Here in the UK the nights are starting to grow longer as we edge towards winter, so I figured it would be a good time to invent a new holiday shakily stolen from Bavaria’s annual Oktoberfest celebration. So, I’m pleased to introduce you to Swiftoberfest: an all-new way to help you learn throughout October.
Here’s how it works: every day in October, from the 1st to the 31st, I’ll be posting a new article here on Hacking with Swift. This will mostly be additions to my Swift Knowledge Base, but there will be some longer ones too.
Yes, this is in addition to me posting a new article every day for my 100 Days of SwiftUI.
So, if you’re following the 100 Days course and Swiftoberfest you’ll get two new articles every day.
Now, I have some bad news and some good news.
First, the bad news: none of those new articles will be about SwiftUI. Yeah, I know – SwiftUI is the cool new kid on the block, but also need to pay some attention to the wealth of other marvelous things Apple make available to us.
Now for the good news: if you follow me on Twitter you’ll know I spend far too much time noodling around with SwiftUI to leave it alone for a whole month.
So I thought to myself: what if I could write a 100 Days of SwiftUI article, a new knowledge base article, and an addition to SwiftUI by Example – three articles every day for a month? Could I do that while also speaking at Mobiconf in Poland and Pragma Conference in Italy?
More importantly, should I do that?
Of course you know the answer already, which is why you know I’m going for the big three: every day for October you’ll get a new chapter in SwiftUI By Example, a new entry in my Swift Knowledge Base or longer article, plus another day of tutorials with my 100 Days of SwiftUI curriculum. Some will be easier and some harder, but I feel confident you’ll learn something new during Swiftoberfest.
Best of all, it’s all going to be free.
To make things easier to find, I’m going to add links below as I post each new article, with the first links arriving tomorrow.
