I got the error when i run react-native run-ios after upgraded RN to 0.26.0-rc.

Resolved with the following advice after running [email protected]:

[...] add -lc++ in Other Linker Flags in your xcode project build settings.

As pointed out in comments update target build settings (and not project). You may also need to update the Test target as well.
