While developing mobile applications, have you ever been faced with the dilemma of choosing between Swift and Objective C. Swift will not only supplant Objective C but also replace C for the embedded programming on Apple Platforms.
Swift’s numerous features can make it an effective programming language to build world-class immersive and responsive mobile applications for the consumers in the years to come. Here are some reasons to indicate why Swift is easier than C and why it is the future:
- Easier to read
In objective-C to differentiate the keywords and types, ‘@’ symbol was introduced. On the other hand, in Swift all the keywords are unified as it is not built on C. The numerous ‘@’ are dropped in front of every object related keywords. Swift has also dropped legacy conventions. Hence, you no longer need to use semicolons to end lines or parentheses to surround conditional expressions inside if/else statements. Another major change in Swift is that method call does not reside inside each other. This reduces the bracket confusion. The method and functional call uses industry standard comma separated list of parameters within parentheses. These changes make language simpler and syntax more unified and cleaner.
- Easier to maintain
Objective-C can’t evolve if C doesn’t evolve. This legacy often makes it difficult to maintain. Programmers while coding in C need to maintain two code files to improve the build time and efficiency. This requirement is even carried forward in Objective-C. These two files are no longer required in Swift. XCODE and LLVM reduce the dependencies and perform incremental builds automatically. The repetitive task to separate the table of contents from the body is reduced. XCODE and LLVM compilers work behind the scene and reduce the work of programmers.
- More Safe
When a null pointer is called in Objective-C, the expression or the line of code becomes no-operation. This may help in preventing crashing of the code, but it is undoubtedly one of the major reasons for bugs as it leads to unpredictable behavior. On the other hand, in Swift a nil optional value generates a compiler error as you write the code. This acts as a short feedback loop. This enables in solving the bugs that may occur as the code is written reducing time, money, and energy spent on fixing the bugs.
- Memory Management
In Objective-C, Automatic Reference Counting (ARC) is supported within the Cocoa API and object-oriented code. This means it is not available for procedural C Code and APIs like Core Graphics. Hence, it becomes programmers’ responsibility to handle memory management. These memory leaks are impossible in Swift. ARC in Swift works across both procedural and object-oriented-code, it handles all the memory management in the application. This lets programmers focus on what is more important thus increasing the productivity.
- Requires Less Code
Swift greatly reduces the code required for repetitive statements and string manipulations. While in Objective-C working with text strings requires numerous steps in order to combine two pieces of information. On the contrary, Swift simply combine two strings with a “+” operator. Swift even supports string interpolation eliminating the need of memorizing the tokens and allows programmers to insert variables inline with a user facing string. This also greatly reduces the chances of crashes.
With these and many other features of Swift, it is more approachable and is a full featured language. These changes easily allow Swift to rise above Objective-C language. Focusing on making an app developer’s job easy, modern compilers are improving and more information can now be inferred from the code.
