# Troubleshooting iOS application tests in AWS Device Farm
<a name="troubleshooting-ios-applications"></a>

The following topic lists error messages that occur during the upload of iOS application tests and recommends workarounds to resolve each error.

**Note**  
The instructions below are based on Linux x86\_64 and Mac.

## IOS\_APP\_UNZIP\_FAILED
<a name="IOS_APP_UNZIP_FAILED"></a>

If you see the following message, follow these steps to fix the issue.

**Warning**  
We could not open your application. Please verify that the file is valid and try again.

Make sure that you can unzip the application package without errors. In the following example, the package's name is **AWSDeviceFarmiOSReferenceApp.ipa**.

1. Copy your application package to your working directory, and then run the following command:

   ```
   $ unzip AWSDeviceFarmiOSReferenceApp.ipa
   ```

1. After you successfully unzip the package, you can find the working directory tree structure by running the following command:

   ```
   $ tree .
   ```

   A valid iOS application package should produce output like the following:

   ```
   .
   `-- Payload (directory)
           `-- AWSDeviceFarmiOSReferenceApp.app (directory)
                         |-- Info.plist
                         `-- (any other files)
   ```

## IOS\_APP\_PAYLOAD\_DIR\_MISSING
<a name="IOS_APP_PAYLOAD_DIR_MISSING"></a>

If you see the following message, follow these steps to fix the issue.

**Warning**  
We could not find the Payload directory inside your application. Please unzip your application, verify that the Payload directory is inside the package, and try again.

In the following example, the package's name is **AWSDeviceFarmiOSReferenceApp.ipa**.

1. Copy your application package to your working directory, and then run the following command:

   ```
   $ unzip AWSDeviceFarmiOSReferenceApp.ipa
   ```

1. After you successfully unzip the package, you can find the working directory tree structure by running the following command:

   ```
   $ tree .
   ```

   If the iOS application package is valid, you will find the {{Payload}} directory inside the working directory.

   ```
   .
   `-- {{Payload}} (directory)
           `-- AWSDeviceFarmiOSReferenceApp.app (directory)
                         |-- Info.plist

   $ tree .
   ```

   If the iOS application package is valid, you will find an {{.app}} directory like {{AWSDeviceFarmiOSReferenceApp.app}} in our example inside the {{Payload}} directory.

   ```
   .
   `-- Payload (directory)
           `-- {{AWSDeviceFarmiOSReferenceApp.app}} (directory)
                         |-- Info.plist
