Context Menus In SwiftUI
We all know about the menu that pops up when you long-press an app on the home screen or how a menu with a relevant options pops up when you long-press a photo in the gallery. That menu behaviour is called the context menu. Learn more about context menus in this week’s Swift Anytime article.
Ultimate Guide On Timer In Swift
Consider an instance where you have to send an OTP from your app and there is a “Resend” option. Think of a use case when a user is spamming the resend option an absurd amount of times. Something like this would end up overloading the server. A potential and most common way to fix it is by using a timer and only showing the “Resend” password option after certain seconds. Take a look at the Timer class in this week’s Timer Guide Article.

Cracking the iOS Interview
What is the difference between classes and structs?
- The difference between a class and a struct is whether it’s a reference or a value. If you need to store some primitive data types (i.e. Ints, Floats, Strings, etc.), use a struct.
- However, if you need custom behaviour where passing by reference is preferred so that you refer to the same instance everywhere, use a class.
- The other difference is that a class supports inheritance, while a struct doesn’t.
Note: Basically in Swift, a struct is preferred over a class.
Why should a lazy property be a variable not a constant in Swift?
You must always declare a lazy property as a variable (with the var keyword) because its initial value might not be retrieved until after the instance is initialized. Constant properties must always have a value before the initialization completes, and therefore shouldn’t be declared lazy.
iOS Good Practices
Specify your app’s colors using asset catalogs
It is a little-known feature of Xcode asset catalogs that allows you to add colors directly. Just like images, color literals can be defined and used throughout the app and referred to as images.
The major benefit of using colors in the Assets catalog is that you can define a color in light and dark modes based on your requirements.
This is how you can access the colors defined using assets:
let primaryTextColor = UIColor(named: "PrimaryTextColor")
let secondaryTextColor = UIColor(named: "SecondaryTextColor")
