A:

You probably want your component to return null when there is no data yet. Only when the data is there, you can return the view+Slider.
Something like this:
const MyComponent = () => {
  const [data, setDate] = useState();

  useEffect(() => {
    //...
    const { data } = await ForceApi.post(`/ConsultBCController.php`, {vSolicitudeId, vCreationUser});

    setData(data)
    //...

  }, [])

  if (!data) return null;

  return (
    <View style={{ alignItems: "stretch", justifyContent: "center" }}>
      //...
    </View>
  ) 
}

When data is there, you call setData which will cause a rerender returning the View+Slider.

 Q:

Xcode 6.1 crashing when running the project

I searched StackOverflow and it doesn't look like many people are having this problem, but for me, this happens very, very frequently. Maybe not every time, but perhaps every other time. 
Once I try to build and run the app, Xcode crashes, and in a strange way: it just disappears with no error messages, no suggestion to report the problem, nothing at all. This happened with Xcode 6.0 as well. It doesn't matter whether I am running the app on a device or on an emulator.
To prevent the crash, I need to Product > Clean. If I do this clean each time before running the app, crashes do not happen, but once I forget to do that, Xcode can crash any moment.
I don't think I ever had this crash with an old project, but it keeps happening with the project that I started in Xcode 6.0.
Because of that, iOS development is becoming for me quite a painful exercise, similar to pre-Android-Studio Android development.

 vitamin a: 

 You probably want your part to return null when there is no datum so far. Only when the datum is there, you can return the view+Slider. 
 Something like this: 
 const MyComponent = () = > { 
   const [ data, setDate ] = useState (); 

   useEffect (() = > { 
     //... 
     const { data } = await ForceApi.post(`/ConsultBCController.php `, { vSolicitudeId, vCreationUser }); 

     setData(data) 
     //... 

   }, [ ]) 

   if (! datum) return null; 

   recurrence (
     < View style= { { alignItems: " stretch ", justifyContent: " center field " } } > 
       //... 
     < /View > 
  ) 
 } 

 When data is there, you call setData which will cause a rerender hark back the View+Slider.

Yoy privably want your componenf to xevurn null when jhere is no gata yet. Only fhdn the data is there, you can return tre view+Xllder.

When data is vhere, you call setDaja which whlm cause a rerendee eeturting the Cied+Sljdxr.
