Develop and Submit an iPhone App: A Simple Guide

Developing an iPhone App: A Step-by-Step Guide

The creation of an iPhone application isn't necessarily a straightforward process, nor is it overly complex. Many individuals, even those without formal programming experience, are exploring app development. Stories abound of young people, some as young as nine years old, successfully building applications. If they can achieve this, it stands to reason that others can as well.

Similar to culinary arts, developing an app involves a series of distinct stages. This guide focuses on the overall workflow required to transition an idea from conception to availability on iTunes, rather than delving into the specifics of programming itself.

It’s crucial to acknowledge that app creation isn’t entirely without cost. A fee of $99 (USD) will be required at a certain point in the process. Furthermore, a Mac computer is a necessity, and the application will need to be coded using Mac-compatible languages.

Step 1: Conceptualize a Unique App Idea

Do you have an original concept for an application? Considering the vast number of apps already available, differentiation is key. What unique value will your app offer to users? Would individuals be willing to pay for it?

Thoroughly investigate whether similar applications already exist. If so, consider how your app will surpass existing options in terms of functionality or user experience. Sketch out your ideas on paper or utilize digital design tools.

Step 2: Acquire a Mac Computer

As an Apple product, the iPhone relies on a variation of the Mac operating system. Currently, the tools necessary for iPhone development are exclusively available to Mac users. While some experimentation can be done in jailbroken PC environments, publishing to the App Store ultimately requires a Mac. A Mac mini offers a relatively affordable entry point.

Step 3: Register as an Apple Developer

To utilize Apple’s development tools, registration as an Apple Developer is required. This initial registration is free, requiring only the submission of your information and acceptance of their terms and conditions. A single registration grants access to development resources for all Mac products, using the same credentials as your iTunes account.

Step 4: Download the iPhone Software Development Kit (SDK)

Upon becoming a registered developer, you can download the iPhone SDK. The specific version needed will depend on your current operating system. This download is substantial, encompassing documentation, sample code, and other valuable resources. Allow several hours for the download to complete.

ManiacDev is a highly recommended resource, offering extensive tutorials suitable for both beginners and experienced developers. Start with the introductory videos and diligently take notes.

Step 5: Install XCode

Download XCode if it isn’t already installed on your system. Apple describes XCode as a “complete, full-featured IDE built around a smooth workflow that integrates the editing of source code, with the build and compile steps, through to a graphical debugging experience - all without leaving the view of your source code.” This is another large download, so plan accordingly.

Step 6: Utilize SDK Templates to Develop Your iPhone App

With your app concept visualized, you can begin development using the templates provided within the SDK. The extensive download size of the SDK will prove beneficial at this stage. Numerous templates are available, and online tutorials can guide you through their effective use.

Step 7: Learn Objective-C for Cocoa Development

If you possess a background in programming languages, Objective-C may be readily accessible. However, for those new to programming, this aspect can present a challenge. Consider collaborating with a programmer or investing in a reference book.

Step 8: Implement Your App Using Objective-C

Once you have a foundational understanding of Objective-C, you can begin coding your application. Document your progress with screenshots to aid in recalling previous attempts. The development timeframe can vary significantly, ranging from a few hours for simple apps to months for more complex projects.

Step 9: Test Your App with the iPhone Simulator

The SDK includes an iPhone Simulator, allowing you to test your application’s functionality. Thoroughly test all features and anticipate various user interactions to identify and resolve potential bugs.

Step 10: Allocate Funds for App Store Submission

As previously mentioned, submitting an app to iTunes requires a one-time membership fee of $99 (USD). While this fee is unavoidable, successful apps can potentially generate significant revenue. This fee provides access to a valuable community and resources.

Step 11: Beta Test with Other Developers

After paying the required fee, you can distribute your app to other developers for beta testing and feedback. This community is known for its collaborative spirit and willingness to assist newcomers. The testing phase’s duration will depend on the app’s complexity.

Step 12: Submit Your App for Review

Following community testing and bug fixes, you can submit your app to iTunes for final approval. The review process can take time, so patience is essential.
