Learning materials for iOS 13 / Swift 5 and 14/5.3: which should I start with?

I bought 2 books for programming in iOS 14 / Swift 5.3. Then, based on someone's recommendation I also bought a highly-rated udemy course for iOS 13 / Swift 5 because it was on sale for $15 with a money-back guarantee so thought I had nothing to lose.

My question, especially to those with programming knowledge/experience in all of iOS 13, 14, Swift 5 to 5.3 is, are there enough differences between iOS 13-14 and Swift 5-5.3 to warrant skipping the udemy course? Or is mostly everything important the same so it may still be worthwhile?

The books I bought:
"iOS 14 Programming Fundamentals with Swift" and "Programming iOS 14" by Matt Neuburg

The udemy course I bought: "iOS 13 & Swift 5 - The Complete iOS App Development Bootcamp" by Dr. Angela Yu

And if you have any other iOS/Swift learning material recommendations, feel free to share. Thanks.
No, there are not that many differences. And anyway, there will be new evolutions with next release.

It depends where you stand: beginner, seasoned developer ?

If you are a beginner, starting with Apple's App development with Swift is good enough to start. And costs nothing.
I took a few Java university courses over a decade ago and have on/off experience with webdev languages like PHP, so leaning toward beginner. I've been reading the Neuburg "Fundamentals" book which so far is quite clear, and have also been perusing the Udemy, Stanford and Hacking with Swift courses, as I believe in learning by doing and will determine which best suits me at the current time. I've also heard good things about Apple's resource so thanks for the suggestion.
