原来Xcode版本是12.2，xcode版本太低，连接ios14.6 和ios15系统的手机没办法真机测试，查了下官网，xcode13支持ios15，于是就是升级后遇到的一连串报错。
一 ：首先碰到的就是Flipper-Folly插件报错： The following build commands failed: CompileC /Users/itkey/Library/Developer/Xcode/DerivedData/speedrn-gdnmwquzchcterhjmywhtacsnjev/Build/Intermediates.noindex/Pods.build/Debug-iphonesimulator/Flipper-Folly.build/Objects-normal/x86_64/DistributedMutex.o /Users/itkey/mac/rn/speedrn/ios/Pods/Flipper-Folly/folly/synchronization/DistributedMutex.cpp normal x86_64 c++ com.apple.compilers.llvm.clang.1_0.compiler (1 failure)
info Run CLI with --verbose flag for more details. error Command failed with exit code 1. info Visit yarnpkg.com/en/docs/cli… for documentation about this command. 解决办法： 修改/ios/podfile文件
添加一个字符串替换的方法
def find_and_replace(dir, findstr, replacestr)
Dir[dir].each do |name|
text = File.read(name)
replace = text.gsub(findstr,replacestr)
if text != replace
puts "Fix: " + name
File.open(name, "w") { |file| file.puts replace }
STDOUT.flush
end
end
Dir[dir + '*/'].each(&method(:find_and_replace))
end
然后在"pod_install"Hooks 中 调用这个替换方法，例：
add_flipper_pods!
post_install do |installer|
flipper_post_install(installer)
# 在这里————————————————添加以下方法调用
find_and_replace("Pods/Flipper-Folly/folly/synchronization/DistributedMutex-inl.h",
"atomic_notify_one(state)", "folly::atomic_notify_one(state)")
find_and_replace("Pods/Flipper-Folly/folly/synchronization/DistributedMutex-inl.h",
"atomic_wait_until(&state, previous | data, deadline)", "folly::atomic_wait_until(&state, previous | data, deadline)")
end
end
修改完后：
- 删除/ios/Pod 目录
- 执行 pod install 或者 pod install --verbose （可以看到pod在做什么）
- yarn ios
二：lottie-react-native插件报错: The following build commands failed: CompileSwiftSources normal x86_64 com.apple.xcode.tools.swift.compiler (in t arget 'lottie-react-native' from project 'Pods') MergeSwiftModule normal x86_64 (in target 'lottie-react-native' from project 'Pods') (2 failures)
解决方法： lottie-react-native 升级到5.0.1 lottie-ios 升级到3.2.3
三：Swift桥接头文件缺失报错： Undefined symbol: _swift_FORCE_LOAD$_swiftFileProvider
解决方法： xcode中右键单击项目为项目添加一个新的Swift文件，步骤： new file -->swift file --> next --> targets 选中项目 --> create 然后会弹一个弹窗，选择Create Bridging Header，最后重新运行项目。
