Fix Library.init() Modernization

This skill fixes Library.init() / Lib.init() calls that the UI5 linter detects as missing apiVersion: 2, and modernizes enum definitions to use DataType.registerEnum — which is required when using apiVersion: 2.

Linter Rules Handled

Rule ID	Message Pattern	This Skill's Action
no-deprecated-api	Deprecated call to Library.init(). Use the {apiVersion: 2} parameter instead	Add apiVersion: 2 to the init call
no-deprecated-api	Deprecated call to Lib.init(). Use the {apiVersion: 2} parameter instead	Add apiVersion: 2 to the init call
no-deprecated-api	Deprecated call to init(). Use the {apiVersion: 2} parameter instead	Add apiVersion: 2 (destructured init)

When to Use

Apply this skill when you see linter output like:

library.js:9:2 error Deprecated call to Library.init(). Use the {apiVersion: 2} parameter instead  no-deprecated-api
library.js:11:2 error Deprecated call to Lib.init(). Use the {apiVersion: 2} parameter instead  no-deprecated-api
library.js:51:2 error Deprecated call to init(). Use the {apiVersion: 2} parameter instead  no-deprecated-api

Background: What Library.init() Does

sap/ui/core/Lib.init() registers a UI5 library with the framework, declaring its metadata: name, dependencies, controls, elements, types (enums), and interfaces. The apiVersion: 2 parameter signals that the library uses the modern initialization pattern.

Important: Only apiVersion: 2 is valid for Lib.init(). Unlike control renderers where apiVersion: 4 is also valid, library initialization only accepts 2.

Fix Strategy

1. No Arguments

Problem: Lib.init() called with no arguments at all.

// Before — triggers no-deprecated-api
sap.ui.define([
    "sap/ui/core/Lib"
], function(Library) {
    "use strict";

    Library.init();
});

Fix: Add an object argument with apiVersion: 2.
