Well - thanks for the effort to solve this!
Sadly the only way I could solve the issue was to role back to unreal engine 4.12.5 - here - everything (the new and the old provisioning profiles - “RFTdevelopment” for instance) work just fine!
I want to note: that I usually never used “RFTDevelopmentAdhoc” to deploy to my iOS devices, it was simply my last attempt trying it out, after I’ve read several answerhub articles and suggestions. Before I decided to write you guys. I just forgot to point out that I tested every available provisioning profile not just the one that might not work anyways. Basically to make sure I don’t bother any of you with a stupid question.
After two reinstalls of macOS to make sure it’s not my fault,
I think Epic Games didn’t had a /time to test macOS Sierra & Xcode 8 with UE sufficiently. Mildly said…
I hope this will be fixed sooner than later.
