If you are an aspiring iOS developer, you know the standout values this platform stands for. When it is about innovation and creativity, this is the platform that offers unlimited and uninhibited potential. You have Swift, the most versatile language at your command and an uncompromising App Store that would force you to align with the optimum standard.
Unlike developers of other platforms, iPhone app developers need to stay continuously updated and tuned to the evolving programming trends and whatever good examples other developers are setting. This is why being frequently acquainted with expert tips is so essential. For anyone willing to hire iPhone app developers having developers updated with latest trends and micro-skills is very important. Let us explain here a few most relevant tips for today's developers of iOS platform.
Are you conversant with Swift 4.1?
Yeah, you have guessed it right. It is the latest Swift update we are talking about. In many respects, this latest update is ahead of previous ones. It comes with few forward-looking aspects that every developer should be conversant with.
No dependence on conditional conformance: With the new Swift version more things are likely to work the way it was not expected earlier. It is simply because the users don't require knowing or being aware of conditional conformance when using libraries. This will help to get many things done that earlier was required a lot of efforts.
Recursive constraints on associated types: The new Swift 4.1 has come with a new generics feature called recursive constraints on associated types. The constraints like presenting the subsequence of a Sequence as another Sequence with the identical element type could not be expressed through the type system. The Swift 4.1 makes the whole thing easier by including these constraints already in the libraries through elaborate Sequence protocol.
Simplifying the generic collection algorithms: Swift 4.1 has come with a crucial advancement. It simplified writing codes for the generic collection algorithms. This will help writing a vast majority of extensions with least complexity. You can also present your collection algorithm in the Swift forums, and it can be included as part of the Swift standard library.
2. Command over protocol-oriented and other programming methods
Most developers quickly refer to protocol-oriented programming when talking about Swift. At least, protocol-oriented programming has emerged as the dominant trend in Swift. But, unfortunately, many are not aware of other methods that are useful for various functions and the limitations of the protocol-oriented method. Protocols offer the advantage of being flexible and simple for many problems, but they are not the only answer to all problems.
Protocols are mostly used in the standard library of Swift for collection, and they are good at it. But just because there are innumerable collection based protocols, often we have a hard time to find the one we need. On the other hand, other methods make things simple for achieving many regular and useful functions. For example, subclassing, generics, values and functions can also be effective in various instances.
Protocols are most effective and useful, but you should only use it after considering the problem in hand. The solution whether it is protocol or generics or values should be chosen based on the problem, not just for taking protocol-oriented programming as a fashion.
3. Working in a code review culture
One of the most important attributes for a developer with high credibility is his experience in working in a code-review culture. The code review gives validation and credibility to the code and plays a crucial role in streamlining a development process which is focused on quality output.
Some priorities that developers should keep in mind for encouraging review of the code include the following.
Ensure delivering small and coherent Pull Request (PR): This is to ensure that there is a small amount of code to review and there is the least number of concerns when the final effects are reviewed.
Maintain the commits as small and coherent: Explain the changes with comments to make the reviewer understand changes and to get more scope of explaining things keep fewer code lines per message.
Ensure telling a clear story with commits: Your messages should deliver a clear story of the entire flow of the app from one point to the other. This will help reviewer understanding changes and incorporate them.
Keeping the changes within context: You need to make the context of all changes clear to the reviewer starting with files and classes changed, the reason of the change, the parameter of change and the choice of new name.
Make the code readable and clear: Finally, keep the code clear and thoroughly readable. Both the code structure and the changes incorporated should offer absolute clarity.
4. Maintaining clarity, familiarity and consistency
Finally, let us spare a few words for the importance of clarity, familiarity and consistency of an app. When delivering custom UI, you must ensure offering UI elements that users are familiar with and can easily utilise. Another important consideration is to ensure the clear hierarchy of elements to ensure the flow of information in the desired way. Lastly, always ensure consistency of design elements throughout the apps to maintain coherent and organic user experience.
To be precise, an app should offer a look and feel that speaks of integrity. The app user experience should be felt exciting but not entirely unfamiliar. You need to meet the user expectations in a delightful manner rather than confronting them with something they are unfamiliar with.
