[ios][14.1.2] Indicator not showing

[heywhy]

The indicator is not showing up on iOS devices. After, going through the repository I found that the indicator is being referenced in the android context but missing in the iOS context.

References:

Line 127 in e667508

this.indicator.setCount(this.items ? this.items.length : 0);

Should be fixed in 14.1.6
