Answer 1

Note:- Only for project which uses both swift code and react-native code
Xcode 8x swift 3x

As a clubbed project which consists of swift and react-native follow the step to run it on the device:-

Open Xcode

Navigate to TARGETS > Build Phases > click on (+)add button

click on New Run Script Phase

In place of

 Type a script or drag a script file from your workspace to insert its path 

place this

 export NODE_BINARY=node /{your project directory }/js/node_modules/react-native/packager/react-native-xcode.sh 

change source URL

from this

return URL(string:" http://localhost:8081/index.ios.bundle?platform=ios ")

to this

this - return Bundle.main.url(forResource: "main", withExtension: "jsbundle")

when you will run the project it will generate an offline .js bundle and fetch all data from that

while running the project make sure you watch the report navigator check if script run successfully or not like the image below

if everything is ok it will run on the device as well as simulator
