Bug description

I have 3 swipers with two-way controls setup.

• Swiper 1 controls Swiper 2
• Swiper 2 controls Swiper 1
• Swiper 3 controls an array [Swiper 1, Swiper 2]

ControllerOptions allows control to be defined as either a single instance of Swiper or an array of Swipers.

However, during actual usage the controller only functions when assigning a single instance, not an array.

Here is the implementation:

export interface ControllerOptions {
  /**
   * Pass here another Swiper instance or array with Swiper instances that should be controlled
   * by this Swiper
   */
  control?: Swiper | Swiper[];

  /**
   * Set to `true` and controlling will be in inverse direction
   *
   * @default false
   */
  inverse?: boolean;

  /**
   * Defines a way how to control another slider: slide by slide
   * (with respect to other slider's grid) or depending on all slides/container
   * (depending on total slider percentage).
   *
   * @default 'slide'
   */
  by?: 'slide' | 'container';
}

Expected Behavior

• Swiper 1 controls Swiper 2 (OK)
• Swiper 2 controls Swiper 1 (OK)
• Swiper 3 controls an array [Swiper 1, Swiper 2] (OK)

Actual Behavior

• Swiper 1 controls Swiper 2 (OK)
• Swiper 2 controls Swiper 1 (OK)
• Swiper 3 controls an array [Swiper 1, Swiper 2] (Not OK)

The same happens for Vue

New Swiper v9 doesn't have Svelte components anymore, it is recommended to use new Swiper Web Components instead.
