How to Fix Shared Progress Issues Across Different Difficulty Levels in SQLite

Improving the Data Saving Mechanism Updating Progress for a Specific Level and Group In the saveProgress method, I updated the SQL query to include both level and quizGroup in the WHERE clause. This ensures we only update the progress for the targeted level and group. Swift let updateQuery = "UPDATE progress SET lastQuestionIndex = ? WHERE level = ? AND quizGroup = ?;" Appl...
