Apple does an outstanding job of encouraging iOS owners to get an upgrade level. IOS 9 will be available and preferred for all iPhone 4 models and newer phones, iPad 2 and both iPad Air devices, as well as the iPod fifth and sixth generation. What kind of opportunities does this open for iOS app developers?
Let’s start with what developers may need to change and vary in their code. Fortunately, the only that should be assessed is the depreciation of the Address Book framework. Developers may have used the Address Book framework to access contacts in their older projects. The good news is that the newer Contacts Framework can be swapped into the accomplishment for the same job.
What is now becoming an annual custom and tradition, the release of iOS 9 also comes with an upgraded level to Apple’s integrated development environment, Xcode, a cloud-based, test-driven development environment. The new Xcode 7 is shipping with Swift 2.0, new testing tools and best UI tools. For the ios 9 app development, Xcode feels exceeding than a mobile-first development tool, rather than OS X-first development tool.
In addition to new features in Xcode, changes and variations are coming to Safari 9. Mobile Safari is the default browser on all iOS appliances. Here are just a few of the many new characteristics in Safari.
- Content is being blocked to speed up the processing of resources, images, CSS and cookies;
- Improvement made in AirPlay media support to broadcast content to your Mac or Apple TV;
- New support system for picture-in-picture video;
- Icons in Pinned Tabs;
- CSS Backdrop Filters.
Apple can encourage millions of people to upgrade with a mixture of press releases and the appearance of the red upgrade badge on the Settings app. With the release of iOS 8, it took 45 days for more than 60% of all active iOS device owners to get an upgrade from 7 to 8. Expect the same with iOS 9 also. This means developers can start building iOS 9 apps that will be used by millions of people now.
- Content layout of developers:
Apple is very much concerned about the layout of the developer’s content. The central rule of content development is that content should fit the screen perfectly such that users won’t have to scroll right or left or won’t get distracted by it. The other three rules of Apple iOS design are depth, clarity, deference and should not be vague.
Depth: This describes a sense of drilling deeper and deeper as users navigate through each screen.
Clarity: This describes making text bold and strong enough such that they can be read quite easily and without any hurdles on any device.
Deference: This describes the fluidity and intuitiveness that all iOS apps must have and have to be more like that. The app must have a neat, clear and simple design that does not overly compete for attention on objects such as text and images.
There are many emulators on the market that you can use to review your layout before publishing it to the app store. Images designs and content should scale to the screen, but there are several screen sizes on the market available. Even if you can’t test them all, make sure that you test the most common ones. Recently, the standardized form is to support the iPhone 5 and newer and code should support at least iOS 9 and Some developers support iOS 8. normally, it is good to maintain backward compatibility of “n-1” from the current released version, however, it is also common to wait until your user base drops below a threshold before deprecating and supporting for a version. It’s the developer’s responsibility to finalize operating versions to support.
Font size and color is another important aspect that must be put into consideration. The font size should be such that users won’t have to zoom in or out to read content and should be proper enough.. The use of a lighter font is typically discouraged, this is because it can be challenging for users to read such content, especially when they are in the sun and also eyesight gets affected.
Before you publish to the App store just ensure that you make use of any of the several emulators to review your layout. It is recommended that those images and content fit device screen. The only challenge is that there are multiple different screens available. Instead, the idea is to make use of the most common sizes.
3. Design UI elements and 3D Touch in mind
For a developer new to mobile app development, it’s very difficult to move from small buttons and links to larger objects that makes it kind of easy for users to select a drop-down item or tap an element.
For instance, when the user taps a drop-down element, a popup button gets displayed with a list of items that the users scroll up or down. Your designed elements should be matched with the target platform. Take a glance at standard elements for iOS. Notice that they are different than Androids. Creating standard UI elements helps make your apps intuitive for the users.
4. Error Handling for Trapping Mistakes
Every coder makes a logical error in their program once in awhile. It’s common for users to enter an unforeseen input that you didn’t handle. For instance, maybe you have an input textbox for a user’s area code. You may be checked for alphabetic characters, but you forget to check for special characters such as an exclamation mark or a question mark. If you then store the data in a numeric storage unit, your application crashes which is of no use.
These types of logical errors should always be handled so that the application never crashes. Instead, an error message should be sent back to the users. iOS apps must use the Error protocol. You can derive your custom error messages from those classes.
5. Creating an Intuitive Project Directory Structure
Having associate intuitive project directory structure isn’t invariably necessary for little basic personal comes, however, once you work with enterprise-level development you’re most likely not the sole engineer to figure on the project however several of them work along. Project directories ought to be organized and intuitive just in case another developer has to maintain or fix your code, it makes straightforward for them.
Without intuitive project structure, your code can get messy, vague and unorganized. In fact, you might have a class that defines the way customers creating an order. If an addition to the order process must be made and the developer can’t find your current present classes, he may end up creating redundant code thinking it has not been written yet.
Never Forget Your Apple ID
Before you can upload your app to the App Store, you compulsorily need an Apple ID. You use this Apple ID to sign your code further. You must need to sign your code before you upload it to the store. The sign identifies you as the coder and developer both. If you develop for a client, send them all the necessary files so that they can upload to the store as well.
An Apple ID is free to create, however, there is an annual account fee of 100$ when you choose to host your applications on the App Store. You can upload any of the apps provided they follow Apple’s Terms of Service. Some clients may add you as a developer to their own accounts so that you can upload and manage the code for them.
It’s best to get this sorted out before the completion of the development process and are ready to upload a compiled app binary so that you can release the app quickly and appropriately for your clients.
