Hello @lukhnos, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

Summary of Changes

This pull request addresses issue #621 by adding a fatal error alert if no installable package is found during the installation process. This enhancement aims to make the installer more robust by providing a diagnostic message in such a scenario. The changes include modifications to the AppDelegate.swift file to display an alert panel and terminate the application if the target bundle cannot be located. Additionally, new localizable strings have been added to both the English and Traditional Chinese localization files.

Highlights

• Error Handling: Implements a fatal error alert when no installable package is found, improving installer robustness.
• Localization: Adds new localizable strings for the fatal error message in English and Traditional Chinese.
• Application Termination: The application now terminates gracefully after displaying the fatal error alert.

Changelog

• Source/Installer/AppDelegate.swift
  • Added a check for a valid target bundle after unzipping the archive or locating the resource.
  • If no target bundle is found, an alert panel is displayed with a fatal error message.
  • The application terminates after displaying the alert panel using endAppWithDelay().
  • Added a return statement after calling endAppWithDelay() when a copy error occurs.
• Source/Installer/en.lproj/Localizable.strings
  • Added a new localizable string for the "No installable packagess found." error message.
• Source/Installer/zh-Hant.lproj/Localizable.strings
  • Added a new localizable string for the "No installable packagess found." error message in Traditional Chinese.
