ios swift Xcode8 TODO FIXME MARK

While coding in Objective-C, #pragma mark isvery handyfor code organization in the Jump Bar. For example:

pragma mark – Initialization code here...

pragma mark – Table Managementmore code here...

pragma mark Alternative for Swift

Xcode 6 now supports a similar feature using // MARK:

// MARK: - Initializationcode here... // MARK: - View Managementmore code here... The “-” after // MARK: is optional, including the “-” results the divider line shown just above the text.

// TODO: in Swift Although not used as frequently (at least from my perspective), but handy none-the-less are FIXME and TODO. The later is nice when you need to set a reminder for code that you need to revisit.

override func viewDidLoad(){ super.viewDidLoad()

// TODO: add configuration code self.configureView()}

You can also add TODO: outside a method as shown below:

// TODO: revisit memory management handlingfunc setupMemoryRecoveryCode(){}

Notice in the screenshot below that the TODO: references appear at different levels – the first TODO: is indented, indicating it is referencing something to do inside the method itself.

// FIXME: in Swift

// FIXME: works in a similar manner, as it can be place either inside or out of a method.

For example, I’ll often place a // FIXME: with a bug reference once I track down the location of the problem. This gives me a marker and I can quickly return to the issue later.

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell{ // FIXME: - Bug 2102 let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as UITableViewCell let object = objects[indexPath.row] as NSDate cell.textLabel.text = object.description return cell}
