iOS Build failed: There was a problem linking the app - Cause by Vungle

I’m trying to build my app for iOS using the latest public build (2016.2380), and it looks like the Vungle plugin is causing it to fail. 

I get the following error in the logs:

Any help would be greatly appreciated

#2

Also using the public build #2016.2376! There is a problem in the last Vungle plugin version (CoronaProvider.ads.vungle).

Wednesday was everything ok. Build process fails from yesterday. :frowning:

#3

I’m getting this error too. Tried multiple different builds and it still happens. Using the latest Xcode/Mac OS X.

#4

Same, thanks for any help!

Vungle has issued a fix:

I should pay more attention to the dates on posts :frowning:

Apparently, Vungle reverted their fix which is causing the same error to reappear.  The quickest resolution will be to contact their support and report the issue.
