Thinking this was a Swift problem, I recreated the project, but with ObjC as
the language. I set up the UI the same as with the Swift project. It too, only
shows a subset of the array, only this one shows 15 rows, not 13. Here's the
ViewController.m

@property NSArray *dwarves;
@end
@implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
self.dwarves = [NSArray arrayWithObjects:@"Sleepy",
@"Sneezy",
@"Bashful",
@"Happy",
@"Doc",
@"Grumpy",
@"Dopey",
@"Thorin",
@"Dorin",
@"Nori",
@"Ori",
@"Balin",
@"Dwalin",
@"Fili",
@"Kili",
@"Oin", // These are not shown.
@"Gloin",
@"Bifur",
@"Bofur",
@"Bombur",
nil];
// Do any additional setup after loading the view, typically from a nib.

#pragma mark "UITableView Methods"
-(NSInteger)tableView:(UITableView *)tableView
numberOfRowsInSection:(NSInteger)section
{
NSInteger theCount = [self.dwarves count];
NSLog(@"theCount = %ld", theCount);
return theCount;
}
-(UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSLog(@"indexPath.row = %ld", indexPath.row);
UITableViewCell *cell = [tableView
dequeueReusableCellWithIdentifier:@"SimpleTableIdentifier"];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:@"SimpleTableIdentifier"];
}
cell.textLabel.text = [self.dwarves objectAtIndex:indexPath.row];
return cell;
}
@end
running it gives me (in the debug console) 4 instances of "theCount = 20",
followed by 15 lines of "indexPath.row = 0" up to "indexPath.row = 14" (15
total, which corresponds to the comment in the initialization line for dwarves
= NSArray... line above.) In both cases (the Swift project, and the ObjC
project) I use the default view (with the size class w:any, h:any) and pin the
UITableView to the edges of the parent view.
Now I'm totally lost as to why only a limited subset of the rows are being
shown, especially given that tableView:numberOfRowsInSection: consistently
returns 20 (the number of items initializing the array). HELP!!
