This Lens Adapter from RhinoShield will let you attach their add-on lenses, including the 4K HD Wide + Macro and Wide + Macro, to your iPhone X, XS, and XS Max.
In addition to the device-specific lens adapter, which is required, a compatible RhinoShield case is required, such as the SolidSuit, Mod NX / Mod, and PlayProof. Lastly, these lens adapters are not compatible with RhinoShield's first generation of lenses, which were made before November 2018.
