Learning the importance of data structures

Data structures are the building blocks of our iOS development. In fact, data structures are the building blocks of many programming languages, and having a deep understanding in that area is the key to success in development and, therefore, passing an iOS interview.

What are considered to be data structures? Well, classes, structs, arrays, dictionaries, and sets are all examples of data structures.

But what precisely makes data structures so important? Here are a couple of reasons why data structures are an integral part of an iOS interview. Let’s list them before we go over some interview questions.

Increasing efficiency

We always have shortages and constraints when we discuss resources. Even though iOS devices have become much more powerful in the last few years, iOS development is no exception to the need for efficiency.

Each data structure has its own strength in terms of time and space complexity; therefore, it...
