[Feature]: iOS build

New Feature

Target Platform

iOS

Feature Description

This app is currently an Android exclusive. I want to provide binaries targeted towards iOS.

Proposed Solution / Mockup

tauri supports iOS builds. There's some plumbing required to make it work.

1. macOS required
2. Install Xcode from the Mac App Store (latest version recommended)
3. Install Xcode Command Line Tools: xcode-select --install
4. Apple Developer Account: Free account works for local testing, paid (99 $/year) required for App Store distribution and bundle signing
5. Add iOS Rust targets: rustup target add aarch64-apple-ios aarch64-apple-ios-sim x86_64-apple-ios
6. Initialize tauri iOS: cargo tauri ios init and review the generated files

• src-tauri/gen/apple/ - iOS project files
• src-tauri/gen/apple/librefit.xcodeproj - Xcode project
• src-tauri/tauri.conf.json - Check for iOS-specific configuration

Config update:

• Update tauri.conf.json with iOS-specific settings:

  {
    "identifier": "io.tohowabohu.librefit",
    "bundle": {
      "iOS": {
        "minimumSystemVersion": "14.0",
        "developmentTeam": "YOUR_TEAM_ID"
      }
    }
  }

• Review and update permissions in the tauri capabilties config

After that, the usual cargo tauri commands can be used for development and local tests.

For CI/CD a ios-templates folder might be needed, similar to android-templates overwriting generated files during the build process.
