Thanks for showing your code. You may need to use Answers to show additional info well formatted. I do not have enough time to watch the session video carefully, but your code seems to be taken from the session video or the sample code for the session. It is intended to be compiled with Swift 5.5/Xcode 13. Please try changing .listStyle(.carousel) to .listStyle(CarouselListStyle()). But there may be other parts you need Swift 5.5.

That error depends on other parts of your code. Can you show your code enough to reproduce the issue?

keyboardGetUnicodeString will return '\r' only...  As far as I tried, I could not find the behavior that return '\r' only. How did you checked it? Your code is not capable of showing control characters. Please try changing print to debugPrint and tell us what you see.

it works just with the valori property but not with the date property Seems the description is not correct enough. When I input 2021 into the textField, the list keeps showing the entries containing 2021. You are using "\($0)".contains(text) for filtering, but do you really understand what sort of Strings are generate by "\($0)"? As far as I tested with Xcode 12.5/iOS 14.5 Simulator, they were as follows: LifetimeInputsModel(id: FB973EBF-D56B-438D-BB8B-5EFDFA63983A, valori: 300.0, date: 2021-06-13 21:35:27 +0000) LifetimeInputsModel(id: 3A57A94C-79EA-4430-90B6-D415C460C243, valori: 200.0, date: 2021-06-14 21:35:27 +0000) Do you want to make the word LifetimeInputsModel hit all entries? Apps should not rely on the default String representations generated by Swift runtime. One possible way, to control the String representation of a struct would be adding CustomStringConvertible conformance. Please try adding this extension to your project and see if the filter works as expected: extension LifetimeInputsModel: CustomStringConvertible { var description: String { return "\(String(format: "%.0f", valori)) \(dateFormatter.string(from: date))" } }

You should better use Code Block when you show some code. If you can edit your post, please try.

I'm not sure if I can help you or not, but showing your code would make your post more appealing and you would get more chance to get better replies sooner. Unfortunately, editing feature is strongly restricted in the dev forums and you may need to use answers to show additional info.

This is not a place to apply to be a beta tester of some specific app. You should better contact to the developer of the app and ask if it is possible.

CocoaPods is not a tool supported by Apple. You should better visit the support sites or communication sites of CocoaPods and/or each framework to get better responses sooner.
