Issue

Trying to run my app on Ios but it crashes at the point it starts using the methods that work with the RNFBdatabse, which get called multiple times.

setLocation: function(geoLocation) : void {
    let uid = auth().currentUser.uid;
    let grid = Geohash.encode(geoLocation.latitude, geoLocation.longitude, 7);
    let dbRef = database().ref(`locationsX/${grid}/${uid}`);

    dbRef.set({
      geo: new firestore.GeoPoint(geoLocation.latitude, geoLocation.longitude),
      time: Date.now(),
    })
    .catch(e => console.log(e))
  },
  createMatches: function(geoLocation) : void {
    let uid: string = auth().currentUser.uid;
    let grid: string = Geohash.encode(geoLocation.latitude, geoLocation.longitude, 7);
    let neighbours = {...Geohash.neighbours(grid), c: grid};
    let locations = [];

    for (const n in neighbours) {
      database().ref(`locationsX/${neighbours[n]}`)
      .once('value')
      .then(docs => {
        docs.forEach((doc) =>{
          if (doc.key !== uid) {
            try {
              locations.push({
                latitude: doc.val().geo._latitude,
                  longitude: doc.val().geo._longitude,
                  time: doc.val().time,
                  profile: doc.key
              })
            }
            catch (error) {
              console.log(error);
            }
          }
        })
      })
      .then(() => {
        locations.forEach(loc => {
          let distanceBewteen = Tdistance([loc.latitude, loc.longitude], [geoLocation.latitude, geoLocation.longitude]);
          let lessThenMin = moment().diff(loc.time, 'm')
          if (distanceBewteen <= 0.2 && lessThenMin <= 5) {
            firestore()
              .collection(`users/${uid}/match`)
              .doc(loc.profile)
              .set({
                ID: loc.profile,
                L: new firestore.GeoPoint(loc.latitude, loc.longitude),
                T: firestore.Timestamp.fromMillis(loc.time),
              })
          }
        })
      })
    };
  }
