I attended the 2015 WWDC and made these notes afterwards. Aside from the specifics re. the Apple Watch and AppleTV, they may be of value to those who are considering streaming sessions next week:

WWDC: Post-show Streaming is the Key to Value

From an editorial perspective, one thing that is …

Rumor has it that Apple will support the Apple Pencil in the forthcoming iPad. If so, more developers will want to use the new features of UITouch -- force, angle, and elevation -- supported by the incredibly-precise stylus.

Basically, it's trivial:

-- Force is UITouch.Force;
-- Angle is UITouch.GetAzimuthAngle(UIView); and
-- Angle …

The premise of the Apple ecosystem is "It just works." It is a world of hardware and software in which you pay a premium for not having to worry about fiddling with configurations and command-line options and incompatibility.

The Airport Time Capsule is a wireless router that also contains a …

There is a company called Round Red Food. They make brain-phones and brain-watches and brain-televisions. These brain-things run brain-books written by Round Red Food. But Round Red Food also allows other people to write brain-books.
​
Round Red Food wants to control what brain-books run on their brain-things. To do this …

I wanted to indicate the most recent move in an AI-on-AI game of TicTacToe, so I wanted to have the most recent move be highlighted. The Xs and Os are CAShapeLayer objects.

Here's the code to do it, ~~featuring a very ugly hack to cast an IntPtr to an NSObject …

I am publicly committing to developing “TideMonkey,” a tide-prediction application that will run on (at least) iOS and watchOS.

TideMonkey will be based on Xtide, an excellent piece of software developed by David Flater. At the moment, my hope is that it will be a very loose port, or what …

Easy-peasy, lemon-squeazy:

[code lang="csharp"]
var a = GKGraphNode2D.FromPoint (new Vector2 (0, 5));
var b = GKGraphNode2D.FromPoint (new Vector2 (3, 0));
var c = GKGraphNode2D.FromPoint (new Vector2 (2, 6));
var d = GKGraphNode2D.FromPoint (new Vector2 (4, 6));
var e = GKGraphNode2D.FromPoint (new Vector2 (6, 5));
var f = GKGraphNode2D.FromPoint (new …

OK, so this is silly, but:

[code lang="csharp"]
var clearRule = GKRule.FromPredicate ((rules) => reset, rules => {
output = "";
reset = false;
});
clearRule.Salience = 1;

var fizzRule = GKRule.FromPredicate (mod (3), rules => {
output += "fizz";
});
fizzRule.Salience = 2;
var buzzRule = GKRule.FromPredicate (mod (5), rules => {
output += "buzz";
});
buzzRule.Salience = 2;

var outputRule = GKRule.FromPredicate …

From an editorial perspective, one thing that is clear about WWDC is that the main audience for the sessions is not the developers in attendance, but the much more diverse, more diffuse, and more transient on-line audience that will view the videos over the next months and even years.

# How to: Handoff to a Xamarin iPhone app from Apple Watch

There are two ways to activate the parent (aka container) app from an Apple Watch app. You can either directly activate the container app using WKInterfaceController.OpenParentApplication or you can use Handoff.

Using Handoff is a little more complex …
