+Xcode and GitHub normally handle these sorts of changes well,
+but sometimes they don't.
+So, you'll probably want to be proactive and change your URLs from
+`https://github.com/stadiamaps/maplibre-swiftui-dsl-playground`
+to `https://github.com/maplibre/swiftui-dsl`.
+
+If you're building a plain Xcode project, it might actually be easier to remove the Swift Package

+Note that the package name also changes with the repo name.
+
+```swift
+    .product(name: "MapLibreSwiftDSL", package: "swiftui-dsl"),
+    .product(name: "MapLibreSwiftUI", package: "swiftui-dsl"),
