Here’s what we know so far, according to the release notes.

Markdown can be used to create Text, whether that be through LocalizedStringKey or a String literal. You can create a Text View with an AttributedString, which I admit is a structure I don’t use very often. There are performance improvements to animations, which makes one of the best frameworks in the world for UI and animation work even faster. …

UPDATE: the problem has now been fixed, although the developers aren’t sure if the problem will surface again.

Polkadot is a Nominated Proof-of-Stake (NPoS) network that has been up and running since May 26th 2020. Users vote to determine which validators do a good job, and in return they get rewarded with more DOT coins. Rival project Cardano (ADA) has a similar system, except that there is no minimum staking amount and the risk is only that a user fails to get rewarded. …

Binance is the world’s largest cryptocurrency exchange, and the last 6 months have been the most profitable of its entire history.

The reason for this recent success is the launch of two blockchains. The first is Binance Chain, a closed source blockchain based on Tendermint that centres around trading BEP2 tokens. These tokens are pegged, meaning they will follow the value of a coin exactly. This concept may be unfamiliar to you but have probably heard of USDT, a pegged token on many blockchains which follows the value of the US dollar.

On Binance Chain there is a pegged token…

The cryptocurrency Dogecoin has had an incredible run this week, fuelled only by hype and celebrity endorsements. Unlike GameStop, where arguments of the company being undervalued can be made, Dogecoin really doesn’t offer any new utility. Maybe that doesn’t matter, but we’re probably going to find out soon enough. Whether you’ve bought into the hype or not, you might be interested to know how to use an API to check the price.

Here’s how the two screens of the app will look:

The original Mac OS X (version 10.0) introduced a new User Interface called Aqua. Steve Jobs was confident that it would look good enough to lick. This was probably due to the way the lighting on the button bubbles made them seem like candy.

This is a tutorial on recreating the Finder window above, which more closely resembles OS X 10.2 (otherwise known as Panther). The main difference between this version and previous versions is the brushed metal background and the lack of pinstripes behind the content.

I’ve achieved this effect with three layers:

• A solid light grey colour
• A…

STEVE: One of the design goals was when you saw it you wanted to lick it. So we call it AQUA, and this is the architecture for Mac OS X. And we are incredibly, incredibly excited and pleased with how this has turned out. Now when we talk about user interfaces, um, let me show you… So these are the user interfaces out there, they’re all credible, they all work. How do we take this to the next level? Well let me show you a few slides on Aqua, and then I’d like to demonstrate for you.

The original Mac…

When you want a property to be saved and loaded from the persistent storage called UserDefaults, you can declare it like this:

@AppStorage(“MyKey”) var savedValue

When the app launches, the key is used to retrieve the value. If there is a value, savedValue will have that value. When you change savedValue, UserDefaults is updated automatically. If you’re displaying the value anywhere in your SwiftUI (e.g. in a Text), the value is updated there too. …
