I recently updated my application with embedded Watch app. Some users reported that the application does not install on their watch. Mine was ok. I had to completely remove iPhone application to reinstall it and reproduce the problem. iPhone is on 11.3 Watch on 4.3. One user report the problem while his iPhone is not yet upgraded to 11.3.
My application have accented character in its name but it has been there for years.
The tricky point is that the error message on the console gives no indication at all :

What could it be ?
Edit: A user installed Xcode and looked at the iPhone console. He found the error with a signature issue:

No Swift in the application. Maybe it is related to TestFlight ? This build was uploaded and testflight loaded before publication.
After struggling two weeks against this issue, I finally foud an explanation and workaround.
Here is the comment I just posted on the bug report 39488346 :
OK, I now have nailed down the issue to an unicode encoding/normalization. By managing to suppress any accented character from any file (coming from the product name) in the Watch application and extension, the Apple signed binary now install correctly on the Watch.
This is a MAJOR recent regression. It appears that WatchOS has recently switched between UTF-8/UTF16 and or between NFC/NFD normalization and that the signature check has NOT been updated accordingly. This explains why codesign on MacOS does not see any signature issue, while the WatchOS reject it.
