Basic Offline Pack (Bounding Box)

import MapTilerSDK

// Define the bounding box
let bounds = MTBoundingBox(
    minLon: 8.5170, 
    minLat: 47.3500, 
    maxLon: 8.5670, 
    maxLat: 47.4000
)

// Create the region definition
let definition = MTOfflineRegionDefinition(
    geometry: .boundingBox(bounds),
    minZoom: 1,
    maxZoom: 12,
    referenceStyle: .streets
)

// Create and download the pack
Task {
    do {
        let pack = try await MTOfflinePack.createPack(region: definition)
        await pack.download()
        print("Download started for pack: \(pack.id)")
    } catch {
        print("Failed to create pack: \(error)")
    }
