Useful video and solution to check if the string is nil or empty. But I think in case of nil check only, the new if let guard syntax should be enough. Learned a lot from your videos. Keep up the good work and happy coding.

a great video would be going through about a dozen examples of different scenarios where a different pattern / implementation makes more sense than others.

Very useful, I have been doing this for a while. I'm doing it like this: extension String? { var isNilOrEmpty: Bool { self?.isEmpty != false } } But I guess the way you do it is a bit cleaner and easier to read.

What about the video about speech recognition in swiftui that you said a month ago that will come soon?

Why didn't Swift just go for implementing null aware operators?

It's unuseful, because the next step to use name variable is unwrapping where we also can check is unwrapped value empty. And it also will be the same one line.

I think this is a very helpful tip. I’m primarily a C# developer and and the string type itself has 2 built in methods for this type of thing string.IsNullOrEmpty and string.IsNullOrWhitespace

Hey everyone in the comments, hes teaching you UIKit which going a little more complex and soon to be outdated. I highly suggest making the switch to learning SwiftUI instead. Get yourself ahead of the curve

Uikit isnt going anywhere soon

Ok this type of optional extension is pretty cool

Personally I much prefer { self?.isEmpty ?? true }. .isEmpty is O(1) while the == isn't.
