Function wait for the loop to be completed then resolve

Question

I have Created one function which should be resolved after completion of loop below

 async function getPPickerid(ppvalue,AssignedToIdArr):Promise<any> {
  return new Promise<any>(async(resolve, reject) => {
  ppvalue.forEach(async(element ,i) => {
  var user = await this.GetUserIdPPicker(element.Key);
   AssignedToIdArr.push(user.d.Id); 
 })
resolve(AssignedToIdArr);

}) }

How to make the function wait for the loop to be completed so that AssignedToArr get some Value and then resolved Array with values
