Rn-fetch-blob: IOSBackgroundTask breaks downloads

[kyle-ssg]

Is there anything else I need to do in order to get background tasks working on iOS, there's not really any documentation?

Downloading files works as expected without this option however fails to work if I set IOSBackgroundTask: true.

• please provide the version of installed library and RN project.
  "react-native": "0.55.4",
  "react-native-fetch-blob": "^0.10.8",

• a sample code snippet/repository is very helpful to spotting the problem.

   return RNFetchBlob
            .config({
                IOSBackgroundTask: true, //onProgress called if this is false
                path: toFile,
                overwrite: true,
                indicator: true,
            })
            .fetch('GET', fromUrl, {
                //some headers ..
            })
            .progress((written) => onProgress(_path,written))
            .then((res) => {
                API.log(`Downloaded ${fromUrl} to ${toFile}`)
            }).catch((err) => {
                API.log(`Error downloading ${fromUrl} to ${toFile}`, err)
                return err;
            })

the exactly same thing is happening with me

Same here too. With IOSBackgroundTask: true or without, if app go to background the download stops. However, background download works well on Android.

does anyone know a better library? this one seems poorly-supported.
