‘mutating’ in Swift

As we all know, Classes are reference type whereas Structures and Enumerations are of a value type in swift. What does that mean is that a class object shares a single instance of the object and passes the same reference if passed to any function or new object whereas the value type is the one which creates a copy of it and passes only the value. read more

‘inout’ in Swift

Recently, while working with swift I came up with a use case where I need to modify the variable passed as an argument to a function. Eventually, all the variables passed to a function are of an immutable type which cannot be changed which is similar to a let variable. read more

Type Aliases in Kotlin

Life is painful when you have two or more classes with the same name but different package name and you have to use them both in the same place. Only one import can be added and the other one needs to be referenced by its complete package name dot class name. Every time you use the second class name, you need to use it by the entire package name of that class. read more

Variable number of arguments (vararg) : Kotlin

Sometimes we need a function where we can pass n number of parameters, and the value of n can be decided at runtime. Kotlin provides us to achieve the same by defining a parameter of a function as vararg. We can pass n number of parameters to a vararg variable of the defined datatype or even of a generic type. read more

Infix Notation : Kotlin

Ever imagined calling a public function of a class without dot and parentheses of the parameter in Kotlin. Kotlin provides infix notation with which we can call a function with the class object without using a dot and parentheses across the parameter. Using infix function provides more readability to a function similar to other operators like in, is, as in Kotlin. read more

Companion object in Kotlin

Unlike Java or C#, Kotlin doesn’t have static members or member functions. Kotlin recommends to simply use package-level functions instead. If you need to write a function that can be called without having a class instance but needs access to the internals of a class, you can write it as a member of a companion object declaration inside that class. read more
