Facebook v4a crashing on ios since today

An app that I was trying to build for debug to my iphone has started to crash out of nowhere since this morning. The device logs point to some issue with the FB kit which we add in the form of the facebook v4a plugin via our build settings.

We actually are not using facebook at all other than as a dependency for Scott’s IrnSrc plugin so we thought we’d try removing the v4a plugin altogether but the app doesn’t build at all when I do that and I get a linking error.

@vlads Could you please confirm if this is due to an update in the plugin because nothing has changed with regards my device or the code since the last time I was able to get the build to run

@Scott_Harrison Can you also confirm that there’s not been an update to the plugin which might be causing this? I’ve tried removing the fb adapter as we weren’t using it anyway but that doesn’t seem to fix it so thought I’d just check with you. From your website, it doesn’t seem there’s been an update.

Here’s the problem as shown in the device logs:

I used a wrong framework with FB Iron, getting a major release which should fix this and update all adapters to newest versions. Should be out later today

Was this fixed? We are still facing the same problem with all our apps that we’re trying to build for iOS.

@Scott_Harrison, was this fixed? (you wrote that you had used the wrong framework). If fixed, when was it fixed? Is it working fine in current version?

This was fixed a bit ago
