Q1:

Build input file cannot be found: '/Users/xxx/Library/Developer/Xcode/DerivedData

• A:X-Code 11.4 [File]->[Worksapce Settings]->[Per-User Workspace Settings]->build System 选择 Legacy Build System

Q2:

directory not found for option '-L-L/Users/xxx/Library/Developer/Xcode/DerivedData/Questionaire-grokfqiwdinmzodhwhvfuwgopznz/Build/Products/Debug-iphonesimulator/CocoaAsyncSocket

• 参考答案

Q3:

'React/RCTBridgeDelegate.h' file not found

• 出现在React-native 0.60.0以后版本
• 解决方案

- Install Cocoa Pods
sudo gem install cocoapods

- In your Project Folder
cd ios && pod install

Q4: React-native打包android后出现莫名的启动闪退现象

A: 根据报错信息定位问题

• 将android手机连接到pc，打开usb调试模式

adb logcat --buffer=crash

logcat打印的报错信息如：
no non-static method "facebook/react/bridge/ReactCallback incrementPendingJSCalls”
大概定位为运行时缺少了brdige的一个方法，原因是混淆器混淆后找不到方法了，可以将ReactCallBack类加入proguard-rules.pro, 缺少哪个增加哪个
-keep class com.facebook.react.bridge.ReactCallback { *; }
