[feat] Improve IDE toolchain and debugging on iOS

[velocitysystems]

Describe the problem

When developing Tauri applications on iOS there is considerable friction with the Xcode toolchain and debugging.

• Xcode does not display all source files, including Rust/Swift code, making it challenging to see the project structure.
• Xcode does not recognize Swift packages that are direct dependencies of the Tauri application.
• It is impossible to inspect or set breakpoints in plugin code, hindering in-depth debugging.
• Log outputs are not easily accessible, which complicates diagnosing runtime issues.

These limitations collectively slow down development and debugging cycles, especially when working with platform-specific features or debugging plugins.

Describe the solution you'd like

1. Ensure that Xcode can load and display all relevant source files, including Rust and Swift.
2. Make Swift packages that are direct dependencies of the Tauri app visible and manageable within Xcode.
3. Add the ability to inspect and set breakpoints in Tauri plugin code, whether written in Swift or Rust.
4. Provide a way to stream and display log outputs more effectively, directly integrated with Xcode’s debugging tools.
5. Reduce build/deploy times.
