By Using the following code you can integrate the Google Maps SDK in your iOS project.

First we will write the function which results the array of related nearby places.

-(void) searchLocation:(NSString *)locationName{
    GMSAutocompleteFilter *filter;
    filter.type=kGMSPlacesAutocompleteTypeFilterGeocode;
    GMSVisibleRegion visibleRegion = _mapView.projection.visibleRegion;
    GMSCoordinateBounds *bounds = [[GMSCoordinateBounds alloc] initWithRegion: visibleRegion];
    [[GMSPlacesClient new] autocompleteQuery:locationName bounds:bounds filter:filter callback:^(NSArray *results,NSError *error){
        if (error != nil) {
            [locationAray removeAllObjects];
            [self.locationTableView reloadData];
            return;
        }
        
        if ([results count]>0) {
            [locationAray removeAllObjects];
            [locationAray addObjectsFromArray:results];
            [self.locationTableView reloadData];
        }
        else{
            [locationAray removeAllObjects];
            [self.locationTableView reloadData];
        }
    }
     ];
}

After that we will use the delegate of UITableView and populate the data in tableview.

# pragma mark tableView Delagate
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
    return  [locationAray count];
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
    static NSString *CellIdentifier = @"location";
    
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
    }
    GMSAutocompletePrediction *alocation=[locationAray objectAtIndex:indexPath.row];
    [cell.lblText setText:alocation.attributedPrimaryText.string];
    return cell;
}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    [self.view endEditing:YES];
    GMSAutocompletePrediction *alocation = [locationAray objectAtIndex:indexPath.row];
    
    [[GMSPlacesClient new]lookUpPlaceID:alocation.placeID callback:^(GMSPlace * _Nullable result, NSError * _Nullable error) {
        if (error==nil) {
            // do your code after selecting the place
        }
    }];
}
