These was massive API update as part of iOS12 release which includes new frameworks:

• AuthenticationServices
• CarPlay
• CoreServices
• IdentityLookupUI
• NaturalLanguage
• Network

Also this release delivers lot of API changes to existing framework which, bright highlights are:

• ARKit 2
• Metal Performance Shaders;
• and others

Beside updating API itself cocoatouch receives lot of patches as result of improvement of bro-gen script.

Following was improved:

• fixed lot of broken enum entires (names were generated cut or prefix was not determinated);
• exposed missing inherited constructors which added lot of missing constructors;
• applied inherited configuration that reduce number of config entries to be put in yaml;
• methods where WithXX was generated were mostly located and correctly renamed (this probably might be a breaking change);
• lot of different minor fixes in generator;

I keep testing some part of it. Please also check if nothing is broken in libgdx
