iOS Google AdMod SDK plugin

[setoelkahfi]

I'm trying to add support for iOS for this Tauri AdMob plugin but got problems adding the SDK to the Swift Package dependency.

PR.

error: failed to run custom build command for `tauri-plugin-admob v0.0.4 (/Users/setoelkahfi/Repositories/tauri-plugin-admob)`

I added the frameworks in the Tauri conf, still the same errors:

    "iOS": {
      "minimumSystemVersion": "13.0",
      "developmentTeam": "team_id",
      "frameworks": ["GoogleMobileAds", "UserMessagingPlatform"]
    }

Any pointers?

The issue is that adding frameworks to tauri.conf.json doesn't actually pull in the dependency. You need to add it to your plugin's Package.swift file.

In your Tauri plugin's iOS directory, find the Package.swift file and add the Google Mobile Ads dependency:

// Package.swift
let package = Package(
    name: "your-plugin-name",
    platforms: [
        .iOS(.v13)
    ],
    products: [
        .library(
            name: "your-plugin-name",
            targets: ["your-plugin-name"])
    ],
    dependencies: [
        .package(url: "https://github.com/googleads/swift-package-manager-google-mobile-ads.git", from: "11.0.0")
    ],
    targets: [
        .target(
            name: "your-plugin-name",
            dependencies: [
                .product(name: "GoogleMobileAds", package: "swift-package-manager-google-mobile-ads")
            ],
            path: "Sources")
    ]
)

The key part is adding it to both the dependencies array and the target's dependencies.

Note: There was a known issue with Tauri and xcframeworks (which Google Mobile Ads uses) but it was fixed in PR #13995 back in August. Make sure you're on a recent version of Tauri (2.0+).

If you still get build errors after adding it to Package.swift, try running cargo clean and rebuilding. The iOS build system can be finicky about picking up new dependencies.

Also worth mentioning - if you plan to use mediation adapters with AdMob, Google recommends using CocoaPods instead of SPM since the adapters aren't available through Swift Package Manager yet.
