IPnPPeoplePickerState.ts

export interface IPnPPeoplePickerState {
addUsers: string[];
defaultmyusers?:any[];
}

In IPnpPeoplePickerProps.ts

import { WebPartContext } from '@microsoft/sp-webpart-base';
export interface IPnpPeoplePickerProps {
context: WebPartContext;
}

Here, in the first Peoplepicker I have bound the values taken from the list (setting default value).

The second peoplepicker is for initialization and saving peoplepicker values to the list.

My list name is program and I have 2 peoplepicker columns, namely Mast and Client, where I have to fetch Mast values from the list and bind in the first peoplepicker

In the second peoplepicker by clicking addSelectedUsers button the values are stored in the client column of the list where I have entered users.

Happy Coding :)
