Its impossible to develope apps for watchOS because symbols for watchOS 19u66 cannot be downloaded:
https://download.developer.apple.com/Developer_Tools/watchOS_19U66/Watch4_3_19U66.dmg
p.s. I thought Apple was a serious company, but I see this is happening continiously since years ago...
Please try again now, should be accessible.
No, it is not available yet :(
Hello? Apple?
Anyone there?
You have to sign in with the correct URL: https://developer.apple.com/services-account/download?path=/Developer_Tools/watchOS_19U66/Watch4_3_19U66.dmg
We can see that now the original link works. It just took only 2 weeks to work.
Thank you!
