  CGFloat timeLineViewX = (self.view.bounds.size.width - timeLineViewW) / 2.f;
  CGFloat timeLineViewY = (self.view.bounds.size.width - timeLineViewH) / 2.f;
  UIView *timeLineView = [[UIView alloc] initWithFrame:CGRectMake(timeLineViewX, timeLineViewY, timeLineViewW, timeLineViewH)];
  timeLineView.backgroundColor = [UIColor blueColor];
  [self.view addSubview:timeLineView];

  CompatibleAnimationView *animationView = [[CompatibleAnimationView alloc] initWithFrame:timeLineView.bounds];
  animationView.contentMode = UIViewContentModeScaleAspectFit;
  animationView.loopAnimationCount = -1;
  animationView.compatibleAnimation = [[CompatibleAnimation alloc] initWithName:@"timeline" bundle:[NSBundle mainBundle]];
  [animationView play];
  [timeLineView addSubview:animationView];
  }

I am facing the same issue. I suppose it comes from the constraints but i have to test

@whisterlee actually found a fix! set translatesAutoresizingMaskIntoConstraints to true on the CompatibleAnimationView

@farfromrefug Thank you so much, you just saved me!

But I want to clarify, you need to fix this line:
