iOS Question Problem building B4i-Bridge

Erel said:

1. Are you trying to build your app or B4i-Bridge?
2. Which version of B4i are you using?

If you are building a new bridge then create a new project, change the package name as needed and create the bridge.

The error here is related to Facebook SDK.

According to the log, he is using version 8. This is part of the error:


He may have to update to 8.5 (since it supports Swift) and his local builder (if he is using a local builder).
