Card Virtual

:  ~ 1 min read

A few months ago I was writing about a new beginning and I mentioned a couple of projects. I mentioned first one in a previous post and now I'm writing about the second.

The main goal of the app is for users to save their fidelity cards digitally (or request new ones), combined with the conveniences of displaying merchants & their offers, and having a shopping list at hand. There's also a friends feature, with which users can share their shopping lists — shopping together, faster and smarter has never been easier!

It's targeted at the local, Romanian, market, but it should be possible to adapt […]

Tower

:  ~ 45 sec read

2 years and a half ago, I was writing about how I recently started using Tower — didn't even realize it's been so long. In that post I was explaining how I solved the fact that it doesn't support opening Pull Requests. Well ... The latest version of Tower now supports it, and I gotta say they're as seamless as one would expect!

A few new features:

Observing and broadcasting

:  ~ 3 min read

The usual solution to observe and broadcast is to use NotificationCenter:

final class Post { // 1

  	var title: String
	var body: String

	init(title: String, body: String) {
		self.title = title
		self.body = body
	}

}

extension NSNotification.Name { // 2

	static let LTHPostReceived = NSNotification.Name(rawValue: "com.rolandleth.com.postReceivedNotification")

}

final class PostCreationController: UIViewController { // 3

	private let post: Post

	// [...]

	private func savePost() { // 4
		// [...]

		let userInfo = ["post": post] // 5
		let notification = Notification(name: .LTHPostReceiv […]

A few months ago I was writing about a new beginning and I mentioned a couple of projects. I would like to present one of them today. It took longer than expected, but we launched today and we're really happy about the results. I'll start with a really short intro:

Our lives are filled with habits; some are good, some are bad. Everyone wants to get rid of their bad habits, and we all want to increase the number and/or frequency of good habits; we all want to eat healthier, do more sport, be more productive, or procrastinate less.

On the other hand, we humans are, by nature, a really sociable s […]

Easier NSLayoutConstraint interactions #2

:  ~ 1 min read

In a previous post I talked about a new struct (LayoutPriority) and a couple of extension methods on NSLayoutConstraint to ease interacting with them. But, as I later discovered, there is no need for the new struct – we can do the same thing on UILayoutPriority itself. Let's quickly see how.

First, we move all the properties along with the operators to the extension:

extension UILayoutPriority {
	
	static let minNonZero = UILayoutPriority(rawValue: 1)
	static let belowDefaultLow = UILayoutPriority(rawValue: UILayoutPriority.defaultLow.rawValue - 1)
	static let defaultLow = UILayoutPriority(raw […]

Creating an interactive label

:  ~ 5 min read

I would like to write about how you can create a label that detects and responds to various UIDataDetectorTypes. Well, we won't really make use of UIDataDetectorTypes, but NSTextCheckingResult, since we'll be using an NSDataDetector. We already have TTTAttributedLabel available, but if you need something much more lightweight, like I did, follow along.

We'll see how we can interact with URLs, but the class should be easily extendable after. Why not use a UITextView, those can do this already?, you might ask; and you'd be right. But UITextViews are expensive to create, and if you need them insi […]

Easier NSLayoutConstraint interactions

:  ~ 3 min read

In Swift 4 UILayoutPriority has become a struct, with an initializer and a rawValue, instead of being a rawValue of Float itself. This means that simple assignments became slightly harder:

let constraint = someView.leadingAnchor.constraint(equalTo: otherView.leadingAnchor)
// Swift < 4
constraint.priority = 999
// Swift 4
constraint.priority = UILayoutPriority(rawValue: 999)

Besides this, I've always had a pet peeve – activating constraints that require priority manipulation:

NSLayoutConstraint.activate([
  someView.leadingAnchor.constraint(equalTo: otherView.leadingAnchor),
  someView.trailin […]

Runtime Sharks

:  ~ 45 sec read

One of my biggest dreams has always been to create a great product of my own, and/or be part of a great team that creates one. Today I took a step towards this dream, and I'm happy to announce that I started a small software company. For now it's mostly me, but I hope in time it'll grow. Such a mixture of feelings ...

Excited. Scared. Eager. Patient. Hard working. Tired. Restless. Hopeful.

Joyful.



By the end of the year we'll have two projects finished, and I can't wait to show them to you. Depending on the project and deadline, we might also be available for collaboration/hire, so don't hesitate to contact us.

Updated to Swift 4 and Vapor 2

Took a while, but it was a bit ... nostalgic 😁.

Please let me know if I missed anything.

IconJar

:  ~ 45 sec read

The other day I gave IconJar a try. It's an app to store, group, preview, search and export your icons. I won't go into much detail, because the feature list is nicely presented on their website, but I'd like to mention one thing, the export function; it has to be one of the best I've seen so far: select one/several icons, select different sizes (manually, or a built-in preset), any color and a suffix/prefix, if desired.

On their website they also offer a few lists of hand-picked icon sets, free and premium, that might be worth checking out; no need to mention, but all of these are already pac […]
