Difference Between SWIFT and OBJECTIVE-C languages.
No need to declare the type (data type) of variable at declaration time (i.e. optional for developers) - Ex: var koti
It automatically allocates memory based on the type of data you pass to the variable - Ex: var a = 5 In the above example we declared and assigned value to the variable ´a´ ¸ it will assign memory for int data type Swift doesn´t require you to write (delimiter) Semicolon(;) after every statement - Ex: var UDI Global = ´Welcome to UDI Global´
Syntax of Swift is more familiar to web developers. The language is very developer friendly that it may be designed to make web developers to build apps.
Swift makes compiles better than Objective-C, because it removes unsafe Pointers management by entirely removing pointers
It allow you to experiment Swift and see the result in real-time.No longer need to compile and run your app in the Simulator, As you type the code in Playground,you will see result as show in above figure.
Thus as the name suggests, Swift is Safe, Modern and by far the most Powerful language for Mobile Apps.
