Can't use Loading / Toast in same method

Ionic Framework ionic-v3

Can’t use Loading / Toast together.

    let loading = Loading.create();
    this.nav.present(loading);
    loading.dismiss();

    let toast = Toast.create({
                    message: 'Do Action',
                    duration: 3000
                });
    this.nav.present(toast);

I want to use in promise method.

thanks.
