  1. Firebase analytics
  2. Firebase Messaging
  3. Unity Analytics Unity IAP
  4. Unity Ads
  5. Google AdMob
  6. Uniweb * this plugin removed on the error log
  7. native share local notifications

plugins in this project


  • I update xcode to 10.1 and try again → result = faild
  • remove firebase plugin and try to build → result = faild
  • remove cocopod, reinstal and update → result = faild
  • Turn off and on unity ads plugin → result = faild
  • Turn unity IAP off and on → result = faild
  • update firebase plugins to lates → result = faild
  • but build simulator version → ist work!!!

try different solutions but they don’t work for me!
any help or suggestion?

Hey, did you solve this issue? I’m currently getting the same thing after implementing unity ads!
