XCode 12 & RN 0.63 Issues & Fixes

Make sure you are using SDK version 1.1.1
Due to change in linking of Pod libraries in iOS to static linking, we have to change how Leanplum-iOS-SDK is linked by adding script in ios/Podfile which will switch Leanplum-iOS-SDK to dynamic linking.

dynamic_frameworks = ['Leanplum-iOS-SDK']
pre_install do |installer|
  Pod::Installer::Xcode::TargetValidator.send(:define_method, :verify_no_static_framework_transitive_dependencies) {}
  installer.pod_targets.each do |pod|
      if dynamic_frameworks.include?(pod.name)
        puts "Setting dynamic linking for #{pod.name}"
        def pod.build_type;
          Pod::BuildType.dynamic_framework
        end
      end
    end
end

After adding the script, make sure you run pod install in ios/ folder
In case you are seeing swift unreferenced symbols, add any kind of Swift file to your main iOS app project in XCode, to force it to link against Swift libraries.

dynamic_frameworks = ['Leanplum-iOS-SDK']
pre_install do |installer|
  installer.pod_targets.each do |pod|
    if dynamic_frameworks.include?(pod.name)
      puts "Overriding the dynamic_framework? method for #{pod.name}"
      def pod.dynamic_framework?;
        true
      end
    end
  end

Just a quick note, if your version of cocoapods is less than 1.9.0, the syntax is a bit different
with that said, here's the fix:

dynamic_frameworks = ['Leanplum-iOS-SDK']
pre_install do |installer|
  Pod::Installer::Xcode::TargetValidator.send(:define_method, :verify_no_static_framework_transitive_dependencies) {}
  installer.pod_targets.each do |pod|
      if dynamic_frameworks.include?(pod.name)
        puts "Setting dynamic linking for #{pod.name}"
        def pod.build_type;
          # Cocoapods < 1.9.0
          Pod::Target::BuildType.dynamic_framework
          # Cocoapods >= 1.9.0
          # Pod::BuildType.dynamic_framework
        end
      end
    end
end
