Angular Material: mat-select not selecting default

Question

I have a mat-select where the options are all objects defined in an array. I am trying to set the value to default to one of the options, however it is being left selected

Answer 1

The solution for me was:

  
  {{moneda.detalle}}

TS:

@ViewChild('monedaSelect') public monedaSelect: MatSelect;
this.genericService.getOpciones().subscribe(res => {

  this.monedasList = res;
  this.monedaSelect._onChange(res[0].id);


});

Using object: {id: number, detalle: string}
