ReactNative - Unhandled JS Exception: SyntaxError

When Im trying to launch my RN app on iOS 8 I get this weird error: Unhandled JS Exception: SyntaxError
And thats all, not any more info more.
Does any1 stumbled across that issue?
On iOs 9+ application runs ok tho.

xCode version: 8.1. Logs from xCode:
2016-12-07 16:33:57.073 [info][tid:main][RCTBatchedBridge.m:73] Initializing <RCTBatchedBridge: 0x7fc36c72ae80> (parent: <RCTBridge: 0x7fc36c060920>, executor: RCTJSCExecutor) 2016-12-07 16:34:29.369 [warn][tid:com.facebook.react.JavaScript][RCTBatchedBridge.m:509] Failed to execute source code: Unhandled JS Exception: SyntaxError 2016-12-07 16:34:29.369 [fatal][tid:main] Unhandled JS Exception: SyntaxError

My package.json:
{ "name": "...", "version": "0.0.1", "private": true, "scripts": { "start": "node node_modules/react-native/local-cli/cli.js start", "test": "jest" }, "dependencies": { "fbjs": "^0.8.6", "moment": "^2.16.0", "react": "15.3.2", "react-native": "^0.37.0", "react-native-chart": "^1.0.8-beta", "react-native-gifted-chat": "0.0.10", "react-native-image-picker": "^0.23.0", "react-native-image-progress": "^0.6.0", "react-native-locale": "0.0.11", "react-native-material-kit": "^0.3.3", "react-native-message-bar": "^1.6.0", "react-native-modal-datetime-picker": "^3.0.0", "react-native-modal-picker": "0.0.16", "react-native-router-flux": "^3.37.0", "react-native-timer": "^1.1.2", "shortid": "^2.2.6" }, "jest": { "preset": "jest-react-native" }, "devDependencies": { "babel-jest": "17.0.0", "babel-preset-react-native": "1.9.0", "jest": "17.0.1", "jest-react-native": "17.0.1", "react-test-renderer": "15.3.2", "whatwg-fetch": "1.0.0" } }

Node, npm and react-native verisons:
adamt@Dev-2 ~/D/G/myApp> npm -v 4.0.2 adamt@Dev-2 ~/D/G/myApp> node -v v4.4.4 adamt@Dev-2 ~/D/G/myApp> react-native -v react-native-cli: 1.2.0 react-native: 0.37.0

Any help to why this error occurs would be much welcomed!

There is an issue React Native version 0.39.

You need to comment out 'use strict'; in line 30 in node_modeles/react-native/Libraries/Core/InitializeCore.js:

// 'use strict'; Fix to RN 0.39 - https://github.com/facebook/react-native/issues/11389

Alternatively, you can go back to React Native version 0.38.
