iOS is the most common OS used mainly in US, UK and Canada. We all know about iOS, but in this blog, we will see the mobile application development platform in iOS. iOS is a bit difficult to use and it has many in-built functionalities. There many iOS mobile development in the market but when we talk about the iOS native apps it clearly gives the idea of swift and objective – C.
Firstly, let’s see what is swift?
Now we will have a look into why we use swift for the iOS mobile app development. There are few things to know about using swift for mobile development in iOS.
Significant features of Swift Programming Language are:
From these features discussed above we can analyse the pros & cons of the swift programming language.
|It is open source||Limited Talent pool|
|Swift’s structures are faster at runtime than classes as optimisation performance is done by compiler||Structs do not support inheritance.|
|Developer can impose full unbending code.||We don’t have identity (===) comparison.|
|As structs are value types, each instance is a unique facsimile of data.||A single struct made up of other value types?—?structs or enums.|
|Easy to read and maintain||Compatibility is not good|
|It is interoperable with Objective - C and it is scalable.||Speed is not enough.|
|Concise & cross device support||Less support with older versions of iOS.|
|Automatic memory management|
Objective – C
Now we will see what is Objective – C?
Objective – C is the programming language of Apple OS & iOS. It gives you language-level support for your object laterals and object graph management.
Why use Objective – C for iOS development?
There are few things to know about Objective – C with which you can analyse why objective – C is significant.
We have always seen that there are always merits and demerits of each and every product. Hence now we will see the merits and cons of Objective – C:
|Many third-party libraries & frameworks are available.||Syntaxes are very uncommon.|
|Good Documentation is available for understanding.||It is slower as it has dynamic runtime.|
|It is stable as it exists since long.||Needs to follow legacy while writing the code.|
|AIt can be easily integrated with C++.||It is hard to learn.|
At the end to conclude we will see the comparison of objective – C versus Swift.
|Swift||Objective - C|
|It can be easily learned.||Migration can be easily done.|
|It cannot be hacked.||Class based Object Oriented|
|Object Oriented and Functional||Cross – Platform.|
|Interactive Playground WYSIWYG editor||Basic Editor|
|It is simplified as it does not need instance variables.||Cumbersome as it needs instance variables.|
|It requires less time to compile as unchanged files are not compiled every time it executes.||Execution time is more as every time whole code is built for each change are made.|
|It supports functional programming.||It does not support functional programming.|
|It is easy to maintain as it resembles English language.||It is difficult to maintain.|
|It does not require to state the type explicitly.||Need to state the type explicitly.|
|Enum value is mapped directly.||Need to assign raw value to enum|
|It works on less coding.||Requires extensive coding|
|It unifies all the keywords which helps in reading the code easily.||Still it uses @ to insert new keyword.|
