What is iqkeyboardmanager?

IQKeyboardManager is a small iOS library that fixes one of the most common annoyances in mobile app development: when the on-screen keyboard pops up, it often slides up and covers the text field the user is trying to type in. Normally a developer has to write code that listens for the keyboard appearing, measures its height, and shifts the screen up so the active text field stays visible. This library handles all of that automatically, the README describes it as a codeless, drop-in solution, meaning you simply add it to your project and enable it once, and from then on every text field in the app behaves correctly. Internally it watches for the keyboard appearing and automatically scrolls or shifts the relevant view so the active UITextField or UITextView stays visible. It works with standard UIKit views and with scrolling containers like UIScrollView, UITableView, and UICollectionView. It supports all interface orientations, lets you configure the distance between the keyboard and the text field, and can be enabled or disabled per screen if it conflicts with a specific view. The library is organised into optional pieces (called subspecs) so you can include only the parts you need, for example a toolbar with Previous, Next, and Done buttons above the keyboard, return-key handling, tap-anywhere-to-dismiss-keyboard behaviour, keyboard appearance options, or a UITextView with placeholder support. Someone would use it on any iOS app that has forms or chat-style input and does not want to manually solve keyboard-overlap on every screen. The library is written in Swift, requires iOS 13 or newer and Xcode 13 or newer, and can be installed through CocoaPods, Carthage, or Swift Package Manager. The author warns it should not be bundled inside other libraries, only used directly in apps. An Objective-C version lives in a separate repository. The full README is longer than what was provided.
