Can anybody help me out? Everything worked fine on my project but after updating to Xcode10 Beta5 I'm getting this error when trying to run the App on my iPhone. Simulator however works… Please Help me!!!

I already did a web search on this problem and found this thread. I tried all answers but none worked..

If you had this problem I would be very very thankful if you can help me running my app on my iPhone again

These are the pods I've integrated: enter image description here

  • Please look in the build log to see what further information is available. – NRitH Jul 31 '18 at 18:31
  • It says: ld: 154 duplicate symbols for architecture arm64. And in the log there are several duplicate symbols for both Crashlytics and Fabric.. How can I get rid of them? – Luke Pistrol Jul 31 '18 at 18:37
  • The error says to pass `-v` to see the invocation. My guess is that Crashlytics and Fabric are being passed to the linker multiple times, causing the duplicate symbol errors. – NRitH Jul 31 '18 at 18:40
  • and where do I pass the -v ? – Luke Pistrol Jul 31 '18 at 18:43

"libstdc++.6.0.9.tbd" is deprecated in iOS 12. In order to solve this, try to go to your

App Targets - General -> Linked Frameworks and Libraries -> Find libstdc++.6.0.9.tbd and delete it.

Then I added "libc++.tbd" and now you will be able to compile your project. Hope It helps.

Ok.. It turned out that something in Fabric and/or Crashlytics was wrong. Since it's not essential for the app I tried to remove both pods and voila it builds and runs.

Finding -l"stdc++.6.0.9" in the "Other Linker Flags" and removing it and adding libc++.1.tbd in the "Link Binary With Libraries" fixed this for me
