I currently use the Prime31 Social plugin for tweeting via the Composer in my game but thought I’d investigate using the TwitterKit SDK instead.
A few things to note:
Hundreds of warnings when building to iOS.

Errors in Xcode that sometimes stop the build.



The last one prevents the build from completing. You have to do a Clean and then rebuild to get success.
Once on device logging in is easy enough but I couldn’t compose without it crashing. I haven’t whitelisted so this may be the reason although I see there are threads from last year about the same crashes.
Also why is there no way to simply compose a text tweet? Using App Cards is the only option it seems.
For now I’m sticking with my current plugin.
