A (micro)blog about programming, photography, and what not.
Swift provides a protocol that you can conform to to let the world know that your objects or structs can be compared and found equal or not: Equatable. There’s also a protocol that allows you to use your objects as keys in a dictionary: Hashable. In an app I’m working on I’m making some of the models (structs) conform to these procotols so that I can make diffing and such when refreshing the UI.

The model has strings for all of the supported locales embeded in it and its just a matter of using the correct one when rendering. The view itself can go through a number of different transitions which is why I need to ask the delegate a few times in a few different places for what locale to use.

All rights reserved. // import Foundation extension String { /** String Without Orphan - Returns: The string with the last space replaced with a non-breaking space to avoid orphans. */ var stringWithoutOrphan: String? { get { let space = NSCharacterSet(charactersInString: " ") if let lastSpace = self.

However, as someone coming from the HTML/CSS programming world I sometimes find that it does not really match up with the mental model I have of how it should work. There’s not any straight forward way of putting a number of absolutely sized items in a stack view and aligning them to either side. You can make them stretch to fill, distribute equally over the entire width of the stack view and you can center them.

(If I was the kind of person to take credit for stuff I’d like to imagine that I sparked the burst of development creating an issue. Luckliy I’m very humble and would never do such a thing. ;))
One thing that I did not really realize when I started freelancing was that potentially customers sometimes asks for a résumé. I hadn’t had a résumé in over six years. And I probably only wrote one or two before that. So last week when I was approached by a company, that I really wanted to work with, asked for my résumé I sat down to write one. I opened up a new Google Docs file and started writing.

A while back I wrote about taking advantage of Node’s require algorithm with Browserify. While I liked the concept of doing that I never really liked how it made things look file-wise. Well. Turns out you don’t need to wrap your little module in a directory or give it a package.json! Say you have a module called… let’s say do-some-math that exports some fancy math functions that are unique do your project.

What remains is a short list of observations, still mostly echoing others. The try-on experience in the store was weird, but kind of fun. I went with the classic leather buckle. Comfort wise it’s comparable to the black sportband (which I also got).

Here’s a simplified version of my view hierarchy: - UIStackView - MyCustomView - UILabel - MyCustomView - UILabel - MyCustomView - UILabel The stack view are laying the custom views out in a horizontal fashion. Now, whenever I added a constraint similar to this: let xConstraint = NSLayoutConstraint(item: label, attribute: .Left, relatedBy: .Equal, toItem: self, attribute: .
