Today an AppleScript function suddenly stopped working:
Asking the Finder for the name extension of a selected file has worked perfectly for years, but it now returns a null string. Yesterday I updated Xcode from 14.2 to 14.3, but it doesn't seem like that should have anything to do with it.
:-/
I'm running macOS 13.3 (22E252)
Any suggestions would be much appreciated.

There is also the brute force Foundation approach:
use framework "Foundation"
use scripting additions
property ca : current application
set foo to ""
set f to POSIX path of (choose file of type "public.plain-text") as text
set fname to ca's NSString's stringWithString:f
set name_ext to fname's pathExtension()
set name_string to fname's lastPathComponent()
if (name_ext's isEqualToString:"txt") = true then
set foo to (name_string as text)
end if
log (foo) as text

As long as you have at least one file selected before you run the script, the code that you have shown, using the name extension, just works for me. In Script Debugger v8.0.5 and Apple's Script Editor. I would put a guard in against no selection… and I have taken some liberty regarding using a list and not the myFileName variable.
Tested: macOS 13.3.
use AppleScript version "2.4" -- Yosemite (10.10) or later
use scripting additions
set foo to {}
tell application "Finder"
if not (get selection) is missing value then
set sel to selection
else
return
end if
repeat with thefile in sel
if name extension of thefile is "txt" then
copy name of thefile to the end of foo
end if
end repeat
end tell
return
Thank you for testing this. I could step through the code and see that the file name was there, including the extension, but the property for the extension was "" (empty string). Capturing the last four characters of the file name [ text -4 thru -1 of (name of theFile as text) ] is working, so I'll leave it that way for now.
Four scripts that used that method had worked for years, but all failed at the same time. I can't help wondering if something in the recent Xcode update could have changed the way AppleScript interprets that in some systems? Quite a mystery. :-/
Thanks. I'm using Script Debugger from Late Night Software. Here I commented out the line that failed, and replaced it with a workaround.
Copy and paste your AppleScript source in the Additional text tool from this editors toolbar. That will be ⋯⃝ and then the document icon.
