would return nil and this could be tested. However, this also demanded that all method calls be dynamic, which introduces significant overhead. Swift’s use of optionals provides a similar mechanism for testing and dealing with nils, but does so in a way that allows the compiler to use static dispatch because the unwrapping action is called on a defined instance (the wrapper), versus occurring in the runtime dispatch system.

Actually I was about to write a comment how you should clarify in the text what this profit means, à la “Your revenue minus server cost is only profit if your labour is worthless”. Then re-read the cost break-down, pleasantly surprised.
Objective-C is the iOS standard, considerd the “correct” language, according to Stephen Kaliski, who works for NYC-based start-up Poptip. The iPhone — and all iOS programming for that matter — is written in Objective-C through Apple’s Xcode integrated development environment (IDE).

At the moment I have 1336 apps in my 64GB iPad & sorting them into folders is a real pain & time consuming esp after a fresh system restore. I wish Apple or someone will come up with a tool or an app to automatically sort them into folders based maybe on the AppStore categories.

Updates are also a good way to give your app a slight “bump” in the eyes of the user. A notification is shown whenever an update is available for an app that is installed on a user’s device, or if automatic updates are enabled, when an app has recently been auto-updated. This notification gives the user a gentle reminder that your app exists, and might prompt them to try out the new version and see what changed.

It does not matter what sort of instance someSortOfPrintableObject is, the compiler will ensure that it conforms to the protocol and thus this code is safe. This syntax also means that collections can be based on protocols also, like let printableArray = [SupportsToString].
My first programming language was Apple Basic, progressing up through C/C++ and many C based web languages since then. I appreciate that the base programming concepts have stayed true, even with moving to visual editors. I think I’m going to enjoy this transition into mobile development.
Speaking of the command line, source control isn’t the only part of development commonly accessed that way. Tons of apps make use of tools like Cocoapods or fastlane when building apps. These aren’t just conveniences; In many cases, they’re critical parts of the development process. A lot of apps simply can’t be built without them. This might be the trickiest part of putting Xcode on the iPad. Let’s be honest: Apple isn’t going to give us command line access to iOS. Even if it did, a lot of command line developer tools rely on modifying data across application bundles in way that isn’t possible on iOS.

Review : I tried a few Udemy courses but just was not feeling the ‘vibe’, it still seemed so hard. Then – I just decided to try again because I am stupid that way. I found Aaron’s course and FOR THE FIRT TIME, this gibberish is starting to make sense. The code actually works on my end and it really is an empowering feeling. Just today, October 9th _ I sent Aaron a financial bonus because he was frankly ‘an answer to my prayers’ and I just wanted to show my gratitude. Aaron also responds quickly which is just very, very cool.
