Thanks for kind wishes. That’s correct, NativeConnect uses Private API, similarly to Fastlane and all other tools for ASO. Let’s hope for the next WWDC, maybe Apple makes them public.
As far as I remember, TestFlight in 2010 used both yours and their own enterprise certificate to sign apps with Apple and distribute them for public. Not sure however, sorry
Could someone explain why the author suggests 4 sizes in the favicon.ico including 24x24 and 64x64? Why not use an ICO with only 16x16 and 32x32 image formats? Thanks in advance.
