Custom Slider Cell with Value Label

[WA-Will]

I'm working to modify the existing slider cell to include a value label. I've shown my modifications here. The slider is in the correct position, but the label showing the value isn't showing. Can you point me in the right direction here?

@interface FXFormSliderCell ()

@property (nonatomic, strong) UISlider *slider;

@end

@implementation FXFormSliderCell

- (void)setUp
{
    self.slider = [[UISlider alloc] init];
    self.field.value = [[UILabel alloc] init];

    [self.slider addTarget:self action:@selector(valueChanged) forControlEvents:UIControlEventValueChanged];
    [self.contentView addSubview:self.slider];
    [self.contentView addSubview:self.field.value];

    self.selectionStyle = UITableViewCellSelectionStyleNone;
}

- (void)layoutSubviews
{
    [super layoutSubviews];

    CGRect labelFrame = self.textLabel.frame;
    labelFrame.origin.y = FXFormFieldPaddingTop;
    labelFrame.size.width = MIN(MAX([self.textLabel sizeThatFits:CGSizeZero].width, FXFormFieldMinLabelWidth), FXFormFieldMaxLabelWidth);
    self.textLabel.frame = labelFrame;

    CGRect valueFrame = self.valueLabel.frame;
    valueFrame.origin.x = self.contentView.bounds.size.width - FXFormFieldPaddingLeft;
    valueFrame.origin.y = FXFormFieldPaddingTop;
    valueFrame.size.width = MIN(MAX([self.textLabel sizeThatFits:CGSizeZero].width, FXFormFieldMinLabelWidth), FXFormFieldMaxLabelWidth);
    self.valueLabel.frame = valueFrame;

    CGRect sliderFrame = self.slider.frame;
    sliderFrame.origin.x = FXFormFieldPaddingLeft;
    sliderFrame.origin.y = self.textLabel.frame.size.height + FXFormFieldPaddingTop;
    sliderFrame.size.width = self.contentView.bounds.size.width - sliderFrame.origin.x - FXFormFieldPaddingRight;
    sliderFrame.size.height = self.textLabel.frame.size.height + FXFormFieldPaddingTop + FXFormFieldPaddingBottom;
    self.slider.frame = sliderFrame;

}

- (void)update
{
    self.textLabel.text = self.field.title;
    self.textLabel.accessibilityValue = self.textLabel.text;
    self.slider.value = [self.field.value doubleValue];
}

- (void)valueChanged
{
    self.field.value = @(self.slider.value);
    self.valueLabel.text = [NSString stringWithFormat:@"%f", self.slider.value];

    if (self.field.action) self.field.action(self);
}
