To animate (fade) text change in UILabel (SWIFT)
The proper way to fade a UILabel (or any UIView for that matter) is to use a Core Animation Transition. This will not flicker, nor will it fade to black if the content is unchanged.
A portable and clean solution is to use a Extension in Swift (invoke prior changing visible elements)
// Usage: insert view.fadeTransition right before changing content
extension UIView {
func fadeTransition(duration:CFTimeInterval) {
let animation:CATransition = CATransition()
animation.timingFunction = CAMediaTimingFunction(name:
kCAMediaTimingFunctionEaseInEaseOut)

To animate (fade) text change in UILabel
CATransition *animation = [CATransition animation];
animation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
animation.type = kCATransitionFade;
animation.duration = 0.75;
[aLabel.layer addAnimation:animation forKey:@"kCATransitionFade"];
// The current text will fade to new text.
aLabel.text = @"new text";

Remove text from the < Back button.
// To be placed in the parent viewcontroller which will push the viewcontroller where the back button should be blank
self.navigationItem.backBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"" style:UIBarButtonItemStylePlain target:nil action:nil];

Spin animation of indefinite duration (not INFINITE). It can be stopped at an even quarter turn if needed. Also, the acceleration ramps up during the first 90 degrees, and decelerates during the last 90 degrees (after a stop has been requested).
// an ivar for your class:
BOOL animating;
- (void)spinWithOptions:(UIViewAnimationOptions)options
{
// this spin completes 360 degrees every 2 seconds
[UIView animateWithDuration: 0.5f
delay: 0.0f
options: options
animations: ^{
