Answer 1

I am using Xcode 7.3.1 targeting iOS 9.3 on OS X 10.11.5.

I had the exact same issue as above with the "Undefined symbols" issue.

I first emptied everything from the "Other Linker Flags" and then added $(OTHER_LDFLAGS) and -ObjC as 2 separate items (using the + button when you double click).

The other thing I did was remove the frameworks giving me issues - GoogleUtilities and FirebaseAnalytics.

I then added them back in using the "Add files to Project" option one at a time and ensured they are targeted to my iOS app.

The build was successful after that and ads show up.

Answer 2

You need to add these libraries

• libc++.tbd
• libsqlite3.tbd
• AddressBook.framework

to Link Binary With Libraries.

Go to Targets -> Build Phases

Answer 3

add two parameter in Other Linker Flags

$(inherited)
-ObjC

Answer for comment above:

Edit: Here is what my Build Settings look like:

The README.md in the Firebase directory said to drag the Firebase.h file into the project, as well as the module.modulemap file and add the path to the module.modulemap file to the User Header Search Paths:

The README.md in the Firebase directory said to enter merely -ObjC here:

Here is what my Project Navigator looks like:

Answer 5

Adding this linker flag fixed the problem for me. I had tried using CocoaPods first, but couldn't get it to import any of the more specific Firebase modules. Adding the frameworks directly worked, but only if the -ObjC linker flag was added.

Answer 6

I fixed this issue by removing FirebaseNanoPB and FirebaseCoreDiagnostics framework from my project.
