UIView

• view.performTransition() does a cross fade of the view from one state to another
• view.performTransitionIfNeeded() same, but only if the animated parameter is true
• UIView.performAnimationsIfNeeded() only animates the changes if the animated parameter is true

• view.shake() shakes the view, usually to indicate an error
• view.shakeWithHapticErrorFeedback() same, but with haptic error feedback

Example:

view.performTransition {
	// update some complex view here, changes will crossfade
}

view.performTransitionIfNeeded(animated: true) {
	// update some complex view here, changes will crossfade
}

// indicates an error by shaking a textfield
inputTextField.shakeWithHapticErrorFeedback {
	inputTextField.becomeFirstResponder()
}

UIImageView

• setImage(_:animated:) sets a new image with a crossfade transition, if animated is true
• setImage(_:tintColor:animated) same, but with a tint color parameter

Example:

imageView.setImage(UIImage(systemNamed: "gearshape"), tintColor: .red, animated: true)

UILabel & UITextView

• setText(_: animated:) sets new text with a crossfade transition, if animated is true
• setAttributedText(_:animated:) same, but for attributed text
• setText(_:textColor:animated:) same, but text & color
• setTextColor(_:animated:) same, but only text color

Example:

label.setText("New text", animated: true)
textView.setAttributedText(newAttributedText, animated: true)

UIWindow

• switchRootViewController() changes the root view controller, with a cross fade animation if wanted

Example:

window.setRootViewController(newViewController, animated: true)

DisplayLink

DisplayLink is a small wrapper around CADisplayLink that uses a block callback and stops the display link whenever it gets deallocated.

Example:

var displayLink = DisplayLink.started {
	print("frame")
}

DispatchQueue.main.asyncAfter(.now() + 1) {
	displayLink = nil
}
