Anything not showing in tableview

hope this fix your issue It's a classic design mistake and reveals the (practical) uselessness of the conditional downcast.
The class of the custom cell in Interface Builder must be set to myCustomCell and the Identifier of the cell must be set to the proper value, too. Then you can remove the guard expression.
code :
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableview.dequeueReusableCell(withIdentifier: cellIdentifier, for: indexPath) as! myCustomCell

    targetStringItem = searching ? searchArr[indexPath.row] : copiedArray[indexPath.row]
    cell.myLableCell1?.text = targetStringItem
    if let indexForSelectedEng = eng.firstIndex(of: targetStringItem) {
        showTheIndex = indexForSelectedEng
        cell.myLableCell2?.text = String(showTheIndex)
    }
    return cell
}

Why is TableView not showing anything.

this one helps. Ok so after clearing this in the comments, your problem is that you haven't set the data source (you can also do this with an array controller). So you set the delegate and the data source:
code :
[TableView setDelegate:self];
[TableView setdataSource: self];
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section;
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell* cell=[[UITableViewCell alloc]init];
    UILabel* label= cell.textLabel;
    label.text= @"Hello";
    return cell;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return 1;
}

Hope that helps Follow these steps:
make an index alphabet array with all starting alphabet of words you are going to populate
code :
//sorting for english language
indexAlphabetArray = (NSMutableArray *)[indexAlphabetArray sortedArrayUsingSelector:@selector(localizedCaseInsensitiveCompare:)];
-(NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView
{
    return indexAlphabetArray;
}
nameDictionary:{
    A:(
       Astart,
       Astop,
     )
    b:(
       bstart,
       bstop,
     )
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return [[nameDictionary valueForKey:[indexAlphabetArray objectAtIndex:section]] count];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *kCellID = @"cellID";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:kCellID];
    if (cell == nil)
    {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:kCellID];
    }
    NSArray *nameArray = [nameDictionary valueForKey:[indexAlphabetArray objectAtIndex:indexPath.section]];
    cell.textLabel.text = [nameArray objectAtIndex:indexPath.row];
    return cell;    
}

TableView Showing Behind Tab Bar


By : Abdus Samad

I hope this helps . I am updating my app to use iOS 7 and I'm having a problem with a table view. My tab bar is translucent. The problem is when I scroll to the bottom of my table view, part of the last cell is still behind the tab bar. I'd like to have a bit of space between the last cell and the tab bar. I could fix this by using an opaque tab bar instead, but I want to keep it translucent. , Try setting
code :
self.edgesForExtendedLayout = UIRectEdgeNone;
self.extendedLayoutIncludesOpaqueBars = NO;
self.automaticallyAdjustsScrollViewInsets = NO;

Showing text over a TableView when scrolling tableView reaches a threshold

wish helps you Your code creates a new UILabel every time user scrolls and hides only the newest one if the condition is met. So try something like this;
code :
let swipeFurther = UILabel()

override func viewDidLoad() {
    super.viewDidLoad()

    swipeFurther.frame = CGRectMake(10.0, 33.0, 300.0, 20.0)
    swipeFurther.text = "Swipe Further to open the settings."
    swipeFurther.textAlignment = .Left
    swipeFurther.textColor = UIColor.whiteColor()
    swipeFurther.font = UIFont(name: "SF UI Text Regular", size: 9)
    self.view.insertSubview(swipeFurther, aboveSubview: self.tableView)
}

func scrollViewDidScroll(scrollView: UIScrollView) {
    if (tableView.contentOffset.y < -(80.0)) {
        swipeFurther.hidden = false
    } else {
        swipeFurther.hidden = true
    }
}
