In source code, becomevendor.ts

displayAddress() {
    this.nativeGeocoder.reverseGeocode(this.becomeVendorDetails.latitude, this.becomeVendorDetails.longitude)
        .then((result: NativeGeocoderReverseResult) => {
            let addressLocal: any = JSON.stringify(result[0]);
            let addressLoc = JSON.parse(addressLocal);
            let addressData = addressLoc.thoroughfare + ',' + addressLoc.locality + ',' + addressLoc.postalCode;
            this.becomeVendorForm.controls['address'].setValue(addressData);
            this.autocomplete.query = addressData;
        })
        .catch((error: any) => console.log(error));
}
close() {
    this.viewCtrl.dismiss();
}

Also this save function is available in other 2 files.

It looks like it is because nativeGeocoder.reverseGeocode returns a list of NativeGeocoderReverseResult

Change result from:

    .then((result: NativeGeocoderReverseResult) => {

to

    .then((result: NativeGeocoderReverseResult[]) => {
