Adventures in Swift and iOS App Development
One of the most powerful and important controls on both wearable and mobile devices are table views. Table views come in two flavors: static and dynamic. Dynamic table views read data from a collection type and displays it. Static tables allow for a vertical scroll view with a set of controls. Static table views are …
It is a myth that using apps on an Apple watch requires a phone. This was true of Watch OS1, but not true of its successor OS. Granted, you still need a phone to load apps, but standalone apps are possible. With the introduction of WatchOS2, this becomes easier as the watch is less dependent …
In the last lesson we created a multi-row table. However, we can only view the table, not select from the table. Multi-row tables provide some challenges with selection. Along the way, we'll make a new interface to display selected information, using a technique we have not yet covered in this series: A dictionary as a …

Some tables are boring. In our multi-part look at the table view in Apple Watch, We've looked at tables with only one kind of row type. However, tables can be lot more than just one row. We might have a header row, or a footer row, we may have sub rows to do some grouping …
In our first part of this series, we made a simple dynamic table for the Apple Watch. Based on some pace data when I ran the Hot Chocolate 15K, we displayed the pace I ran at the mile splits. In a real running app, I would not want to add or delete any of my …

In the last post, we looked at scroll views and static tables. There are many instances where tables filled with data at runtime are necessary. If you are familiar with UITableViewController, you may be delighted to know that WKInterfaceTable is a lot simpler to put together: there are no delegate or data sources involved. It's …

To state the obvious, The Apple Watch has very small screen real estate. There are times we need more screen space than is available. In iOS, there are scroll views. One subclass of scroll views are the table views. Table views come in two flavors: static and dynamic. Dynamic reads data from a collection type …

Menus are cool. Since the first interactive program, there have been menus in applications. The Apple Watch is no exception, but has no space to put a menu. To solve this problem, Apple uses the new force touch gesture to pop open a menu. You can make your own menu, with customized icons and captions. …
Apple's documentation for WatchKit is quite clear, even when it is lying. The documentation states you can have hierarchical navigation or page navigation but not both. Here's is where it lies: you can have a page-based navigation as part of a hierarchical navigation scheme. There is a special modal view version of page views, which …

In the first part in this series we implemented a modal interface in WatchKit with a segue. In this part we'll present the modal programmatically and once again set up a delegate and context for moving data between controllers. Open the project from the last lesson. Press Command-N and add a new Cocoa Touch class …
