iOS 14.0 brings us many improvements and new APIs using which the developers can write efficient code. One such API is the closure based action API instead of the addTarget method in UIControls. Yes, you heard me right—no more usage of addTarget methods, #selector(), and @objc annotation in front of methods. More importantly, we can write a closure based code using the action handler. Okay, enough talk, let’s dive into the code.

Almost every app requires photos and video access these days. Before iOS 14.0, the iOS developers used UIImagePickerController to access the items from the user’s media library. From iOS 14.0, Apple is providing its developers a brand new way to select images or videos from their apps using PHPickerViewController

One of the most significant features which make an app stand out is localization. When we hear the term localization, the first thing that comes to mind is localizing the text displayed in UILabels, UITextViews, UIButtons, and other UIElements. It is quite straight forward to localize the text in the UIElements, and most of us think that we have localized the app, and it is ready to go! But wait, there is one more area I would like to highlight, and that is the images used in the app. You heard me right. If the images used in the app contain text, then they should be localized as well. Localizing the image assets is slightly different but not so hard.

As a developer, we might use Userdefaults in our apps at some point in time for storing some basic configuration or settings in the app. But as the project gets complex, things can get pretty tough. Especially, when you want to clear all the UserDefaults values from the app. Well, we can use the removeObject method to remove the value for a particular key.

At WWDC 2019, Apple added a brand new API “UICollectionViewCompositionalLayout” to the UIKit. Using this powerful API, we can create complex compositional layouts without writing complicated code. At times, It feels tough to create complex collection view UIs using the UICollectionViewFlowLayout. The UICollectionViewCompositionalLayout API eases the process and guess what you can even support orthogonal scrolling UIs with much ease. Well, it sounds great, but practically we cannot use the UICollectionViewCompositionalLayout API until we drop the support for iOS 12.0 and earlier in our apps. (It is not going to happen for the next few years is what I predict.) So how do we use this API in iOS 12.0 and earlier?
