Publish static XCFramework (iOS)

[louwers]

If you want to try it out add

https://github.com/louwers/maplibre-gl-native-distribution.git

to Swift Package Manager. This uses this Package.swift.

For some reason Xcode downloads all package products... So it is a lot slower than before (depending on your connections speed).

Select MapLibreStatic:

To get it to work you need to make two changes:

1. Add -ObjC linker flag.

2. Download the XCFramework and copy the .framework file to the application directory. https://github.com/maplibre/maplibre-native/releases/download/ios-v6.21.1/MapLibre.static.xcframework.zip
