DC Voltage -> pin 1 is ground on the right, pin 5 (three pins in between) 5 Volts
Old cables didn't even pass continuity but still charged?

We'll walk you through everything you should turn on or off in the iPhone's camera settings app.

1. Switch to 4k resolution
2. Shoot at 24 frames per second
3. Turn off “HDR Video”
4. Turn on “Grid”
5. Turn off “View Outside Frame”
6. Turn on “Macro Control”

An unofficial bonus chapter for the iOS Human Interface Guidelines: Learn how to structure iPhone apps with drill-downs, modals, pyramids, sequences, and more.

Design apps quickly by using Sketch and Photoshop templates, plug-ins, and preconfigured UI elements.

For the first 5 or 6 years of iPhone releases, screen sizes were pretty manageable. If your design worked on a 320x480 screen, you were golden. Now, it’s the wild west out there. Every year seems to come with at least another screen size 🙄…

Using Apple Configurator 2
Download an app from App Store to you phone
Open Apple Configurator 2 on your Mac and log into your Apple account
Connect your phone to your Mac using a USB cable
Into Apple Configurator 2 select your phone
Then tap on the “Add” button in the top, then tap on “Apps” button
Choose the app and tap on “Add” button
Finally it could tell you an app already exists, but don’t worry — just be in a hurry to grab an .ipa using this path:
~/Library/Group\ Containers/K36BKF7T3D.group.com.apple.configurator/Library/Caches/Assets/TemporaryItems/MobileApps/

It’s got:

• Horizontal rulers at the top of the frame showing where (1) page actions, (2) page title, and (3) the search bar (if applicable) go
• Horizontal rulers at the bottom of the page showing where the tab bar goes
• Vertical rulers at (1) the standard iOS side margins and (2) the centerline
• A single-layer status bar – easy to delete or change to white, as needed
• A single layer device outline (including notch)

And it makes it dead simple to lay out apps in a “typical” iOS style.

Web apps written with Svelte are blazing fast. While you could certainly use a technology like Apache Cordova to create a mobile app, you're likely better off using a JavaScript-Native framework like NativeScript.

Having created my first app using Flutter, I weigh up the technology’s pros and cons against the other big cross-platform development contender — React Native

What are remote Push Notifications?
Well if you ask the folks at Apple, they will probably direct you to this page on their website where they describe notifications as follows:

Apple Push Notification service (APNs) is the centerpiece of the remote notifications feature. It is a robust, secure, and highly efficient service for app developers to propagate information to iOS (and, indirectly, watchOS), tvOS, and macOS devices.

After immersing myself in it for a year, I find Swift to be deeply web in its soul. From its expressive, functional syntax and its interpretive playgrounds to its runtime performance and recent foray into open source, Swift is the web developer’s compiled language (with the mature and convenient safeguards characteristic of the compiled environment).

Everything you need to get you started is here. It’s free. And the community is amazing.

I built this tutorial to serve as a guide to creating a hybrid mobile application combining both native iOS controls and Cordova/PhoneGap components to leverage the best of both worlds as an alternative to picking one over the other. Developers may choose to do this if they want to use specific native UI features but still code the bulk of their business logic in JavaScript or reuse existing JavaScript logic by embedding it as a Cordova component while maintaining the rest of the native scaffolding. There are also benefits to using this approach in making an application feel more native.

Since Apple announced Swift as the new modern language for their products, I’ve been wanting to learn it. Even though my background isn’t programming, I decided to give it a shot. A little more than a month ago, I finished my 100 Days of Swift Project.
