'symbol(s) not found for architecture x86_64 in Xcode 10 (ERROR)

I am facing the problem in my ios project. symbols not found for architecture x86_64 in Xcode clang: error: linker command failed with exit code 1 (use -v to see invocation). I nuked my xcode and project folder multiple times trying to get around this. I'm stuck. Any ideas? The log is below. I am trying to run a simulator build on Xcode 10.

  Undefined symbols for architecture x86_64:

ios xcode

Solution 1:^[1]

Inside pods, under targets, click on React then, build phases > link Binary with libraries add DoubleConversion.Framework and glog.framework and Folly.framework. Whenever you do pod update please make sure these are added under react dependencies then run.

Solution 2:^[2]

in React.podspec your need change

ss.compiler_flags       = folly_compiler_flags

ss.dependency             "DoubleConversion"
ss.dependency             "GLog"
ss.compiler_flags       = folly_compiler_flags

3 part

ps: GLog or glog

Solution 3:^[3]

I am facing the same problem on 12 feb either. So I opened an issue for this problem on Github.

There is a workaround for this problem.

Manually adding DoubleConversion and glog to Link Binary With Libraries of React framework target in @CocoaPods project.

And this issue fixed in RN 0.58.4

Solution 4:^[4]

Solution was so easy, when I Read error message....

Just add x86_64 arch to ur dependecy. I havent it, cuz i added React-Native to existed ios app, and it has some diff with app, which created with React-Native as default. React-logger -> Build Settings -> Architectures
