Ry’s Objective-C tutorial — for “oldschool” Objective-C fans. You don’t have to truly master Objective-C (Swift is the future ), but it’s good to know the basics and to be able to read the code written in this language.

These industry experts also wrote great reviews in the App Store which I think made a big sales difference. Now the policies have changed so users who downloaded the app with a promo code cannot write a review. I’ve never been featured or had any promotion from Apple. So all of the numbers below are from my marketing efforts outside the App Store.

Apple intended Swift to support many core concepts associated with Objective-C, notably dynamic dispatch, widespread late binding, extensible programming and similar features, but “safer” (easier to catch software bugs); Swift has features addressing some common programming errors like null pointers and provides syntactic sugar to help avoid the pyramid of doom. Swift supports the concept of protocol extensibility, an extensibility system that can be applied to types, structs and classes, which Apple promotes as a real change in programming paradigms they term “protocol-oriented programming”[10] (similar to traits).[11]

It’s also worth considering that it takes some effort to maintain each app over time: building new versions to benefit from bug fixes, removing outdated content, taking advantage of new features, etc. Although it is possible to retire apps eventually, you will probably want to update most of your apps from time to time.

Delegation is a design pattern that enables a class or structure to hand off, or delegate, some of its responsibilities to another object. In this course, we look at how we can use the delegate pattern in our code to avoid tight coupling as well as how it is used throughout Cocoa Touch.

But submission can be a bit more difficult if you don’t have OS X.  You can’t upload an app from a Windows PC to iTunes Connect because you need a program called Application Uploader…which is only available on Macs. The easiest way to get around this problem is to borrow a friend’s Mac or use a service like MacinCloud.

Touch and hold your finger on the app icon until you enter edit mode (the icons begin to jiggle).If you want to drag multiple apps, use a second finger to tap each additional icon and add it to your stack.

Lastly, there’s the question of design components and a heavy user interface impacting performance and speed. Make sure that coding and lots of calls in the programming don’t slow down the application. A lot of it has to do with increasing interaction with users, and it’s a good idea to reduce the coding burden by allowing custom input views (keyboards) and gesture recognition.
