Hello, I picked up this book in 2025 and I’m trying to run with Xcode 16.4. I’m facing several issues as noted by other questions in this forum on the topic.
examples:
error: Couldn’t look up symbols:
RxSwiftPlayground_Sources.example(of: Swift.String, action: () → ()) → ()
Hint: The expression tried to call a function that is not present in the target, perhaps because it was optimized out by the compiler.
I am aware of the book being tested with Xcode Version 11. But it would be nicer if the source code were available with a more recent Xcode version like Xcode 16 or Xcode 26. Happy to help with Open source contributions if it would help here.
Thanks!
