+# alex-bootcamp
 
-If you have the necessary React Native and npm development environments already installed, then clone this repo and type
+# Fixes for iOS https://github.com/abolger/surveyjs-inside-react-native-webview:
 
-'react-native run-ios' or 'react-native run-android' at the command line and be prepared to be amazed! 
+## 0. Remove lock files
+
+```bash
+rm yarn.lock package-lock.json
+```
+
+then generate fresh one with `yarn` or `npm install`
+
+## 1. Upgrade react-native
+
+```bash
+react-native-git-upgrade
+```
+
+as a result it will also bump `react` version, change some
+`ios/` and `android/` files, `.gitignore`, `.babelrc` and .`flowconfig`
+
+IMPORTANT: make sure there are no errors in command output
+with a big probabilty there will be conflict(s) in `ios/SurveyJSInWebViewWithReactAndReactNative.xcodeproj/project.pbxproj`
+just accept incoming git changes there
+
+PS if you run `react-native-git-upgrade` again it can throw an error about unavailable babel plugin
+to make the command pass you may need to remove `.babelrc` and return it back after
+
+## 2. Update babel preset
+
+```bash
+yarn remove babel-preset-react-native
+```
+
+```bash
+yarn add metro-react-native-babel-preset -D
+```
+
+even though `react-native-git-upgrade` supposed to make the preset change,
+double-check that `.babelrc` is like :
+
+```js
+{
+  "presets": ["module:metro-react-native-babel-preset"]
+}
+```
+
+## 3. Add `native-base`
+
+```bash
+yarn add native-base
+```
+
+## 4. Update React-Native-Webview-Bridge.xcodeproj
+
+`yarn add react-native-webview-bridge` (currently 0.40.1)
+
+Optional: You may need to also follow README for iOS here https://github.com/alinz/react-native-webview-bridge
+(to make sure `Library/React-Native-Webview-Bridge.xcodeproj` references the project from the fresh npm package)
+
+## Optional: 5. Update other packages
+
+This step do not require any code fixes, just bump them :)
+Only leave both `react` and `react-test-renderer` at version 16.6.3
