The Model-View-Controller Pattern (MVC) is particularly essential in iOS change. The contemplation is, that there are essentially three layers:

The model layer is the data and business method of reasoning layer. This layer shouldn't talk with the point of view layer clearly.

The point of view layer involves the things that manufacture the UI. Awesome case for this is UIButton, UITableView and UILabel. The viewpoint layer isn't allowed to address the model layer and it should not have any business justification.

The controller layer stays amidst the model and view layer. Since the model and view layer are not allowed to address each other, it is the control of the xamarin certified developer layer to allow the model and view to layer collaborate.

Regardless, when in doubt the controller layer fundamentally more than it should do. All the time an extensive measure of the business method of reasoning and stuff that the viewer should do can be found in context controllers. Along these lines, see controllers tend to wind up especially huge. This is a terrible programming layout. So it's imperative to endure this at the highest point of the need list.

UI operations other than the major string

In case you are encountering to a great degree impossible to miss bugs that are difficult to imitate, it is likely that there is a multithreading issue in your application. Honestly, UIKit isn't string safe. Most architects consider this yet in spite of all that it happens routinely that UI stuff is done offside the standard string since it's definitely not hard to disregard to jump back to the essential string. So be mindful, if you are executing synchronous code.

Testing just on the test framework

The iOS test framework is fast and extremely usable. By using the iOS test framework you can quicken your headway and it's considerably less difficult to get to the record course of action of your application. Regardless, the iOS test framework isn't a bona fide contraption so that there are conditions where device and test framework act in a startling way. Also, the iOS test framework has significantly more execution than a certifiable contraption, with the goal that the test framework isn't the perfect choice to test the execution of your application.

Testing just on the most up and coming contraption

So it's a shrewd idea to use the test framework and in addition an authentic device. Regardless, that isn't all. It's moreover not a keen idea to test just on the most a la mode and snappiest contraption. Imagine you are developing an iPad application and you are attempting just on the iPad Pro. Regardless, you have to consider that iOS 9 still sponsorships the iPad 2 and that the execution of the iPad Pro is incredibly enhanced than the execution of the iPad 2. So it could happen that your application carries on incredible on the iPad Pro yet repulsive on the iPad 2. Clearly, you don't have always all devices, yet you should hold up under that at the highest point of the need list. Likewise, in case you have a couple of devices, you shouldn't use just the most breakthrough one.

Not considering memory use

It's real that the compiler and iOS does by far most of the memory dealing with for you. Regardless, this doesn't suggest that you shouldn't contemplate memory use. It's as yet possible to have memory spills. This could happen due to affirmed hold cycles. Especially in case you are using delegates, this could happen quickly. So you should pay thought on this issue. Moreover, you should in like manner considers the memory utilization of your application. You can do this either in instruments or in the "explore pilot" tab in Xcode:

Power Unwrapping Optionals

One of the essential purposes behind Swift is to make to a great degree safe code. One central part to fulfill this are optionals: Non-optional qualities need a value and should not get the opportunity to be nil. So if you require a quality to have the probability to wind up nil, you have to report the value as an optional:

Not remaining cutting-edge

iOS progression is evolving quickly. Reliably the platform has new developments and that is clearly reflected in the change instruments as well. So there is no point where an iOS design knows enough. Or maybe, he needs to take in all the time remembering the true objective to remain in the current style. There are a couple of ways to deal with do thusly: For example, you could read online diaries, tune in to podcasts or watch video courses. Books are as yet a conventional way to deal with learning things and there are a lot of good iOS progression books out there. Here just a little summary to give you an impression:

iOS Programming: The Big Nerd Ranch Guide: Very awesome preface to iOS headway. Some programming foundation is required. If you don't have any programming information by any methods, you should start with the going with the book:

Snappy Programming: The Big Nerd Ranch Guide: Excellent book for novices.

Focus Data: An outstandingly sensible manual for Core Data.

Sensitive Skills by John Sonmez. This book isn't about iOS change. In any case, in case you have to improve your business, you should examine xamarin certified developer.

Wrong UITableViewCell reuse

To wrap things up I wanna see the UITableView cell reusing trap. UITableView is a basic portion that is used as a piece of skirting on every io application. It moreover has awesome execution. It finishes this by reusing cells, that infers that cells are reused when the customer is investigating. Thusly new cells don't should be made, which would have a more noteworthy execution cost. Regardless, if not all properties are reset precisely, abnormal things can happen.
