# iOS Setup

## Configure Background Capabilities

- Select the root of your project.  Select **Capabilities** tab.  Enable **Background Modes** and enable the following mode:

- [x] Background fetch
- [x] Background processing (Only if you intend to use `BackgroundFetch.scheduleTask`)

## Configure `Info.plist`
1.  Open your __`Info.plist`__ and add the key *"Permitted background task scheduler identifiers"*

2.  Add the **required identifier `com.transistorsoft.fetch`**.

3.  If you intend to execute your own [custom tasks](#executing-custom-tasks) via **`BackgroundFetch.scheduleTask`**, you must add those custom identifiers as well.  For example, if you intend to execute a custom **`taskId: 'com.transistorsoft.customtask'`**, you must add the identifier **`com.transistorsoft.customtask`** to your *"Permitted background task scheduler identifiers"*, as well.

:warning: Your custom  task identifiers **MUST** be prefixed with `com.transistorsoft.`.

```dart
BackgroundFetch.scheduleTask(TaskConfig(
  taskId: 'com.transistorsoft.customtask',
  delay: 60 * 60 * 1000  //  In one hour (milliseconds) 
));
```

## Privacy Manifest

Apple now requires apps provide a [Privacy Manifest for "sensitive" APIs](https://developer.apple.com/documentation/bundleresources/privacy_manifest_files/describing_use_of_required_reason_api?language=objc) which could be abused for "fingerprinting" a user for malicious marketing activity.

If your app does not yet have a *Privacy Manifest* (__`PrivacyInfo.xcprivacy`__), create one now:

<details>
    <summary>ℹ️ Click here for detailed instructions...</summary>

- In XCode, __`File -> New -> File...`__:

- Be sure to enable your `Targets: [x] YourApp`:

It's best to edit this file's XML manually.
- :open_file_folder: `ios/PrivacyInfo.xcprivacy`
- Add the following block within the `NSPrivacyAccessedAPITypes` `<array>` container:

```xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

<plist version="1.0">

    <key>NSPrivacyAccessedAPITypes</key>
    <array>
        <!-- [1] background_fetch: UserDefaults -->
        <dict>
            <key>NSPrivacyAccessedAPIType</key>
            <string>NSPrivacyAccessedAPICategoryUserDefaults</string>

            <key>NSPrivacyAccessedAPITypeReasons</key>
