Adaptation Guide
The count attribute of VibratePreset is optional. If your app has a dependency on the type of this attribute, adaptation is required. For example, if the type of count is a number before change, you need to set the type of count to number|undefined after change.
let effect: VibratePreset = {
type: 'preset',
effectId: 'xxx',
count: 2
};
let count: number|undefined = effect.count;
