# Bundle Pixel harness for iOS

A real iOS app with a real WKWebView. It runs the six ad setups from the test bench's Real apps tab:

| Setup | How the ad is loaded | What the tag should report |
|---|---|---|
| Plain WebView | `load(URLRequest)` | no bundle (iOS has no header fallback) |
| Bundle in ad URL | `load(URLRequest)` with `?bundle=` | the app's bundle id, from the URL |
| MRAID 3 with MRAID_ENV | ad HTML wrapped with MRAID_ENV and mraid.js | the bundle id, from MRAID_ENV |
| MRAID 3 getEnvironment | ad HTML wrapped with mraid.js | the bundle id, from getEnvironment() |
| MRAID 2 with macro | `%%APP_BUNDLE%%` replaced in the ad HTML | the bundle id, from the macro |
| Cross-origin iframe | sandboxed iframe in the page | no bundle |

## Build

1. In Xcode, choose File, New, Project, iOS App. Use Swift and UIKit with a storyboard.
2. Set the bundle identifier to `cc.cleartrust.bundlepixel.harness`. Any identifier works; the test bench compares against whatever the app reports.
3. Replace the project's `ViewController.swift` with the one in this folder.
4. To test against a test bench on your Mac over http, add `NSAppTransportSecurity` with `NSAllowsArbitraryLoads` set to YES in Info.plist. The hosted test bench is https and needs nothing.
5. Run on a simulator or an iPhone, check the server field, and tap **Run all**.

Results show in the app at the end and in the test bench's Real apps tab. Safari's Web Inspector can attach to the WebView on iOS 16.4 and later.
