<p style="color:#000000" class="has-text-color wp-block-paragraph">Previously on this blog I posted an introduction to iPhone app development. Therefore this post shows the next step for the up and coming developer. In this case the tutorial shows how to create a calculator.  In particular the app shows how a single event handler can process more than one event. The image below is the link to the video tutorial. Also see below for the text version.</p>

<p class="has-text-color has-very-dark-gray-color wp-block-paragraph">Firstly how to write a Simple iPhone App for Beginners is a common question. Therefore this is a tutorial on iPhone app development using Xcode and Swift. Also have you ever thought about writing iPhone apps in your spare time? Furthermore the incomplete &#8220;how To&#8221; videos out there are frustrating and presenters prevent understanding by excluding some critical steps. Consequently I have set out to solve this by making complete app creation videos for beginners.  Above all for those who have never coded in their lives. Therefore the video below (click on the image) shows how to make a simple app using <a rel="noreferrer noopener" aria-label="Xcode (opens in a new tab)" href="https://developer.apple.com/xcode/" target="_blank">Xcode</a> and <a rel="noreferrer noopener" aria-label="Swift (opens in a new tab)" href="https://developer.apple.com/swift/" target="_blank">Swift</a>. Likewise the companion guide below shows how to write a simple iPhone app for beginners. Finally <a href="https://sapphiregee.com/iphone-app-development-for-beginners/">The Sapphire Blog</a> is the repository for all posts to this site.</p>
