While building my application and running it for ios 10 (xcode 8), I ran into an issue with the Facebook4 cordova plugin. I tried updating everything via
ionic plugin state restore
Which seemed to work correctly, as it updated the facebook4 plugin to version 1.7.4
After trying to build with it
ionic build ios
I receive this build error.
CompileC build/38Plank.build/Debug-iphonesimulator/38Plank.build/Objects-normal/i386/FacebookConnectPlugin.o 38Plank/Plugins/cordova-plugin-facebook4/FacebookConnectPlugin.m normal i386 objective-c com.apple.compilers.llvm.clang.1_0.compiler
It seems to not like the plugin on build.
