viewForHeaderInSection stopped working in xcode 8 - ios

Question

I have a tableView with 2 sections, the sections array is fixed with 2 elements. The headers for the sections showed fine as code shows below in Xcode 7. I just upgraded to Xcode 8, and the section headers don't show anymore, the code below doesn't get called anymore.
Any ideas?
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.frame.size.width, 18)];
/* Create custom view to display section header... */
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(10, 5, tableView.frame.size.width, 18)];
[label setFont:[UIFont boldSystemFontOfSize:16]];
NSString *date =[sections objectAtIndex:section];
/* Section header is in 0th index... */
[label setText:date];
[view addSubview:label];
[view setBackgroundColor:[DeviceHelper Orange]]; //[UIColor colorWithRed:166/255.0 green:177/255.0 blue:186/255.0 alpha:1.0]]; //your background color...
return view;
}

Answer 1

Use this method as it is, you will see the header
NB : set the delegate and datasource of tableView
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 50;
}
- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
{
return 100;
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 3;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section;
{
return 5;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath;
{
static NSString *reuseId = #"reuseid";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:reuseId];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:reuseId];
}
cell.textLabel.text = #"Test";
return cell;
}
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.frame.size.width, 18)];
/* Create custom view to display section header... */
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(10, 5, tableView.frame.size.width, 18)];
[label setFont:[UIFont boldSystemFontOfSize:16]];
NSString *date = #"22nd Sept 2016";
/* Section header is in 0th index... */
[label setText:date];
[view addSubview:label];
[view setBackgroundColor:[UIColor orangeColor]]; //[UIColor colorWithRed:166/255.0 green:177/255.0 blue:186/25
return view;
}

Make sure you have heightForHeaderInSection in addition to your viewForHeaderInSection function
- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
{
return 30;
}
