Trying to get data from storage but it returns empty array

I have data stored using custom keys. I want to return all data that starts with the id KEY- so I loop over all the data and storage and push the ones that match into an array. I can see that the data is being pushed into data[] but when I call getData() in my component it returns an empty array. What am I doing wrong?

storage.ts

getData(): any {
  this.storage.ready().then(() =>
  {
    let data = [];
    this.storage.forEach((value, key, index) =>
    {
      if (value.id.startsWith("KEY-")) {
        data.push(value);
        console.log(data);
      }
    });
    return data;
  });
}

component.ts

ionViewDidLoad() {
    this.data = this.storage.geData(); 
}

I've also tried this way

ionViewDidLoad() {
    this.storage.getData().then(data => console.log(data));
 }

So just return a promise from your function then try to resolve data with this promise. 

getData(): any {
  return this.storage.ready().then(() =>
  {
    let data = [];
    this.storage.forEach((value, key, index) =>
    {
      if (value.id.startsWith("KEY-")) {
        data.push(value);
        console.log(data);
      }
    });
    return data;
  });
}
