SwiftObjective-C
In a

swift, the variable and constants are declared before their use

In objective C, you have to

declare variable as NSString and constant as int

You

have to use “let” keyword for constant and “var” keyword for variable

In objective C, variable is

declared as “ and constant as “

There is

no need to end code with semi-colon

The code ends with semi-colon
Concatenating

strings is easy in swift and allows to make a new string from a mix of

constants,  literals, variables, as well as expressions

In objective C, you have to

choose between NSMutableString and NSString for string to be modified.

Swift

does not require to create a separate interface like Objective C. You can

define classes in a single file (.swift)

For classes, you create separate

interface (.h) and implementation (.m) files for classes

Swift

enables you to define methods in class, structure or enumeration

Objective does not allow this
In

Swift, you use “ +=” Operator to add an item

In C, you use “addObject”:

method of NSMutable array to append a new item to an array
