OSM map not showing in minimal map example on ios

[tatami shark]

Hello,

I'm trying the minimal map example from:

https://doc-snapshots.qt.io/qt5-5.9/qtlocation-minimal-map-example.html

I get an empty blank map on:

• Qt for iOS Simulator 5.10.1 and on
• Qt for iOS 5.10.1 on an iPhone SE

On Android, Desktop QT the map is showing.

I'am using Xcode 9.3.

I have modified the code such that the error property of the Map is
printed :

Map {
...
id: map
onErrorChanged: {
console.log("Map error: " + map.error)
}
....
}

On iOS this prints out:
qml: Map error: 1

I'm helpless because of the error on iOS.
What's wrong?

I would appreciate your help.

Thanks
