);Troubleshoot
- When installing
react-nativeversion >= 0.60, XCode shows this error:
duplicate symbols for architecture x86_64
That's because the .a library uses CocoaAsyncSocket library and Flipper uses it too.
Podfile
...
use_native_modules!
# Enables Flipper.
#
# Note that if you have use_frameworks! enabled, Flipper will not work and
# you should disable these next few lines.
# add_flipper_pods!
# post_install do |installer|

# end
...and comment out code related to Flipper in ios/AppDelegate.m
