Top 5 iPhone App Developer Interview Questions
What is the difference between synchronous and asynchronous execution in iOS?
Asking this question can help you understand a candidate's understanding of concurrency and how they approach solving problems in iOS. Asynchronous execution is critical in iOS to prevent blocking the user interface and maintain performance. A candidate who understands the difference between synchronous and asynchronous execution can better manage resources, increase app performance, and avoid crashes.
An experienced iOS developer would answer this by explaining that synchronous execution blocks the current thread of execution, while asynchronous execution allows other tasks to execute while the original task is waiting. They would explain how to use Grand Central Dispatch (GCD) to perform asynchronous execution and avoid blocking the main thread, which would lead to a better user experience.
Can you explain the MVC design pattern in iOS?
This question helps you determine a candidate's understanding of software design patterns and their familiarity with the Model-View-Controller (MVC) pattern, which is widely used in iOS app development. Understanding the MVC pattern is crucial because it helps to separate the user interface from the data model, making it easier to maintain and test code.
A good iOS apps developer should begin by explaining that the MVC pattern consists of three main components: the Model, which manages data and business logic, the View, which displays the user interface; and the Controller, which acts as an intermediary between the Model and the View. They would then provide an example of how to implement MVC in an iOS app.
What is the difference between a delegate and a notification in iOS?
This question assesses the candidate's understanding of inter-object communication in iOS and how they approach decoupling code. Delegates and notifications are two common ways to communicate between objects in iOS. Understanding the difference between the two and when to use them can lead to more maintainable and testable code.
A strong candidate would explain that a delegate is a way for one object to communicate with another by allowing the second object to define a protocol that the first object must adhere to. Notifications, on the other hand, are a way for an object to broadcast information to any other object that is interested in it. They would then explain when to use each approach, given a specific scenario.
How do you handle background tasks in iOS?
This question evaluates whether the ios app developer has the ability to multitask in iOS and how they approach managing background tasks. Background tasks are essential for iOS apps, especially those that need to fetch data or perform updates while the app is not in the foreground.
Skilled iOS developers would answer this question by explaining how to use the Background Fetch and Remote Notification features in iOS to manage background tasks. They would also explain how to use the URLSession and NSURLConnection classes to perform background downloads or uploads.
What is the difference between a storyboard and a xib file in iOS? Answer following the above pattern
Asking this question in an interview can help you determine a candidate's understanding of iOS user interface design and how they approach building the user interface. Storyboards and XIB files are two methods used in iOS to design user interfaces.
A strong candidate would explain that a storyboard is a single file that contains multiple scenes or screens and can help to manage the flow between them. Storyboards allow for more comprehensive visualization of the app's user interface and navigation flow. On the other hand, XIB files are individual files that represent a single screen or view. XIB files can be reused across different screens and are often used when creating custom views.
The candidate should also be able to provide examples of when to use each method and how to implement them effectively in an iOS app.
