I am using Swift and Google Maps and have saved some tiles for overlaying in a zoom/lat/lng.png structure at my document directory (like file:///....documents/3/2/3.png)

 let urls: GMSTileURLConstructor = {(x, y, zoom) in

        let url = "(documentsUrl)(zoom)/(x)/(y).png"

        return URL(string: url)

 }

 layer = GMSURLTileLayer(urlConstructor: urls)

 ...

The snippet is working for online layers without problems. But when documentsUrl is my local directory, I receive

Task .<1> load failed with error Error
Domain=NSURLErrorDomain Code=-1100 "The requested URL was not found on
this server." UserInfo={NSLocalizedDescription=The requested URL was
not found on this server.,
NSErrorFailingURLStringKey=file:///.........../Documents/7/65/42.png

Is there any chance getting offline tiles working with Swift + Google Maps?

Thanks a lot

Just use your own class and override the tileFor-function

class OfflineTileLayer: GMSSyncTileLayer {

    override func tileFor(x: UInt, y: UInt, zoom: UInt) -> UIImage? {



        let documentsUrl =  FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first!



        let reqPath = URL(string: "(documentsUrl)(zoom)/(x)/(y).png")!.path

        print (reqPath)

        if FileManager.default.fileExists(atPath: reqPath) {

            print ("> IS ACTIVE!")

            let url = NSURL(string: reqPath)

            let data = NSData(contentsOf: url! as URL)

            return UIImage(data: data! as Data)

        }



        return kGMSTileLayerNoTile

    }

}

and call it from your map init function with

 offlineLayer = OfflineTileLayer()

 offlineLayer.map = yourGoogleMap
