# Add Custom Map Style - Swift SDK

[MapTiler SDK iOS](https://docs.maptiler.com/mobile-sdk/ios/) is a set of tools for creating and customizing maps on your mobile devices, using Swift language. In this guide you will learn how to add a custom map style, created in your MapTiler Cloud, to your mobile application in a few simple steps. If you haven’t already, read through our [Getting Started](https://docs.maptiler.com/mobile-sdk/ios/examples/get-started/) guide to set up your project and initialize the map view.

## Create your own map

If you haven’t already, follow the [How to make custom map design in MapTiler](https://docs.maptiler.com/guides/map-design/editor/) guide and create your own map. Once your map is ready, open it, scroll down to the Use Vector Style section and copy the style json url.

## Load your custom map

Getting your custom map style loaded can be done in only couple of steps.

1.  Prepare you project and set up the map using our [Getting Started](https://docs.maptiler.com/mobile-sdk/ios/examples/get-started/) guide.
2.  Set the _referenceStyle_ to _.custom_ and use the style link you copied previously as a string, replacing `YOUR_CUSTOM_MAP_URL`:

### UIKit

```swift
if let url = URL(string: "YOUR_CUSTOM_MAP_URL") {
  let map = MTMapView(frame: view.frame, options: MTMapOptions(), referenceStyle: .custom(url))
}
```

### SwiftUI

```swift
MTMapViewContainer(map: map) {}
  .referenceStyle(.custom(URL(string: "YOUR_CUSTOM_MAP_URL)))
```

And that is it! Your custom map is ready. Build and start your app.
