hi, nice application.
I tried running on OSX version 10.15.7 and XCode 12.0.1, at the first run the application running well. (running well for the first time after startup)
However, the 2nd, and so on the application didn't work. it seems cannot discover the polar device.
after restart running well, but the problem comes again for the 2nd run. here I attach a screenshot for the 2nd run and console log.

Hello,

Could you describe the exact steps you made?

I've just recompiled on my current machine. I'm on Xcode 12.1 now, and it's stable with my Polar H10:

hi, thank you for your response.

I forgot to mention MacBook Pro (13-inch, 2020) and Polar H10 in the previous running of the program which shows advertisementData[CBAdvertisementDataLocalNameKey] nil.

However, I've just tried on MacBook Pro (13-inch, 2017) the program runs well.
is it hardware issues?

What I made: start the app, put on my H10, switch off H10, put on again. On my 2019 16" latest code version worked well.
