Can I assign a value from ReactJS Native to a Swift global variable? If so, how?

Is there any (straightforward) way to assign the value of a Swift global variable (of double_t type) from ReactJS Native JavaScript? Or (scaling back from an XY question) is there any other way to make a (floating-point) Number computed in ReactJS Native JavaScript, and access it from a .swift file?

Solution

  • No. At least not directly.

    You can make your own Native Module that React Native can call on and get data from. This allows you to write some native code that has a method that can be called to deliver the info you need. Then you write some javascript to that calls that method.

    Note the Swift Specific documentation here.
