# preorderDate

The date the customer placed an order for the app before it’s available in the App Store.

```
let preorderDate: Date?
```

## Discussion

This date is present if your app is available for preorder and the customer places an order before your app is available in the App Store. When your app becomes available, the App Store fulfills the customer’s order. The [`preorderDate`](/documentation/StoreKit/AppTransaction/preorderDate) remains the same.

Use this date to recognize customers who place preorders.

For more infomation about preorders, see [Offering Your Apps for Pre-Order](https://developer.apple.com/app-store/pre-orders/).
