# MapReader

A container view that defines its contents as a function of information about the first contained map.

## Declaration

```swift
@MainActor @preconcurrency struct MapReader<Content> where Content : View
```

## Overview

Overview The map reader’s content builder receives a MapProxy instance. You can use this instance to get the information you’ll need to convert between a MapCamera and a MKMapRect or MKCoordinateRegion.
