# iOS

Scandium currently only supports iOS Simulator builds (**.app**). A simulator build can be run in the iOS Simulator with Xcode. AppStore distribution device builds (**.ipa**) are not currently supported.

## Finding your .app file

### Using Xcode

The easiest way to get the iOS Simulator build is to run and build your application in Xcode while targeting an iOS Simulator

Once the build is complete and the app is running in the simulator, you can locate the `.app` file by navigating to **Product** -> **Show Build Folder in Finder** -> **Products/Debug-iphonesimulator**

### Using Xcode Command Line Tools

You can also generate the iOS Simulator build of your app by building it directly via the command line using `xcodebuild`.

**With .xcodeproj**

```shell
xcodebuild -project '{project_name}.xcodeproj' \
 -scheme '{scheme_name}' \
 -sdk iphonesimulator \
 -configuration Debug
```

**With .xcworkspace**

```shell
xcodebuild -workspace '{your_workspace_name}.xcworkspace' \
 -scheme '{scheme_name}' \ 
 -sdk iphonesimulator \
 -configuration Debug
```

The `app` file can then be found under

```
build/Debug-iphonesimulator/
```

## Compress your app file

Once you have located your `.app` file, Scandium requires it to be in a compressed `zip` or `tar.gz` file e.g.

```
zip -r {app name}.zip {app name}.app
```

## Troubleshooting

If you are having trouble running your uploaded iOS app on Scandium, we recommend trying to run the same app on a simulator provided by Apple in Xcode.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.getscandium.com/mobile-application-testing/uploading-apps/ios.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
