Creating Real Device .ipa Files for Appium and XCUITest

note

To install your iOS app on our real devices we need to include our own provisioning profile in your app. For that, we use a resigning process to include our provisioning profile in your app. While this process does not modify the functionality of the app, it touches certain entitlements in your app.

In order to disable the resigning process, you must buy your own private devices with dedicated provisioning profiles, see here. Once you have such private devices, disabling can be achieved in one of these two ways:

1. Using an ad-hoc provisioning profile: embed the private device's UDID in the profile.
2. Using an enterprise certificate: this does not require you to embed the device's UDID in the provisioning profile.

Creating .ipa files for Appium testing

Building an .app Bundle

1. Open your app project in Xcode.
2. Select a Generic iOS Device or Any iOS Device (arm64) as your product's device target.
3. In the Product menu, select Clean.
4. In the Product menu, select Build.
5. Navigate to your Xcode project's Products directory and find the generated .app file.

Building an .ipa from an .app Bundle

1. Create an empty directory with the name Payload.
2. Move the .app file inside the Payload directory.
3. Compress the Payload directory into an archive (.zip file) and give it a new name with .ipa appended to the end of the file name.
4. Your .ipa file is now ready for upload to Sauce Labs.

Building an .ipa File

You can use any of the existing methods of distribution for your iOS app, except for the App Store type. This means that you can choose any of the three other export methods: Ad Hoc, Enterprise, or Development.

Recommendation

We highly recommend to use Ad-hoc and Development targets to get the most out of our capabilities. Enterprise-signed apps have limitations, and in some cases we are not able to install Enterprise re-signed applications due to Apple restrictions and protections.

1. Open your app project in Xcode.
2. Select Generic iOS Device or Any iOS Device (arm64) as your project's device target.
3. In the Product menu, select Clean.
4. In the Product menu, select Archive. When the archiving process completes, you'll see your app listed under Archives.
5. Select your app and click Export.
6. When prompted for an export method, select Ad Hoc, Development or Enterprise.
7. Set these Distribution options:
   1. App Thinning: None.
   2. Clear the selection Rebuild from Bitcode.
   3. Strip Swift symbols is optional.
   4. Clear the selection Include manifest for over-the-air installation.
8. Select your Distribution Certificate and Provisioning Profile (Automatic or Manual). This will generate the .ipa file.
9. When the file generation process completes, click Export and choose where to save the .ipa file.
10. Your .ipa file is now ready for upload to Sauce Labs.

Creating an XCUITest Package

note

saucectl supports archiving from .app to .ipa Testing with XCUITest when devices are used during the configuration of your suites.

1. Open your app project in Xcode.

2. Select Generic iOS Device or Any iOS Device (arm64) as your project's device target.

3. Make sure that your UI tests are part of a Target Membership and that those Targets are selected to be built in your Xcode Build scheme. Targets containing UI Tests are typically selected to be built at the "Test" build action.

   

4. Generate your test package by selecting Product > Build For > Testing.

5. Navigate to your Xcode project's Products directory and find the generated .app files.

Creating .ipa Files for XCUITest Testing

Make sure that you set the same iOS version for your app and test runner iOS Deployment Target. If they don't match, your tests will run locally, but fail when you run them against Sauce Labs real devices.

To set the iOS version in your Xcode Project:

1. Select the Project you want to build.
2. Under Build Settings, set the iOS Deployment Target to the iOS version you want to use in your test. All target outputs of this project, including the app and your test runner, will be set to the same iOS version.

To set the iOS version in your Xcode Target:

1. Select the Target for your Project.
2. Under Build Settings, set the iOS Deployment Target to the iOS version you want to use in your test.

caution

This will also overwrite the Build Settings at the Project level to that iOS version. If you use this method, be aware that your Targets can become out of sync with each other and the Project settings, and your tests will break. If you change the iOS version for one target output, you may want to build the Project again to make sure all your targets are in sync.

Sauce Labs Resigning Enablements

Public Devices

Sauce Labs applies its own resigning to apps that are installed on our public iOS devices. Our resigner includes the following keychain-access-groups entitlements:

Key	Value
application-identifier	<string>XXXXXXXXXX.*</string>
keychain-access-groups	<array>   <string>XXXXXXXXXX.*</string>    <string>com.apple.token</string> </array>
get-task-allow	<true/>
com.apple.developer.team-identifier	<string>XXXXXXXXXX</string>
com.apple.developer.ubiquity-kvstore-identifier	<string>XXXXXXXXXX.*</string>
com.apple.developer.ubiquity-container-identifiers	<array>   <string>XXXXXXXXXX.*</string> </array>
inter-app-audio	<true/>
com.apple.developer.networking.networkextension	<array>   <string>app-proxy-provider</string>   <string>content-filter-provider</string>   <string>packet-tunnel-provider</string>   <string>dns-proxy</string>   <string>dns-settings</string> </array>
com.apple.developer.siri	<true/>
com.apple.developer.pass-type-identifiers	<array>    <string>XXXXXXXXXX.*</string> </array>

Private Devices

If your organization or application requires specific entitlements to be present, Sauce Labs allows you to disable resigning for private devices. To access our private device cloud, contact your Sauce Labs account executive or our support team. When resigning is disabled, you may sign your app using your own provisioning profile, or install an application that is signed with an Enterprise certificate, which can include any entitlements.

To disable the Resigning, you can either visit "App Management > {Your App} > App Settings" (App Settings) to disable resigning globally for your app.

You can also use the sauce:options capability resigningEnabled=false to disable app resigning for automation. This option is available for private devices only.

Common Errors

Unable to Verify App

If you are facing the issue where the app crashes with a red screen and an "Unable to Verify App" popup:

that means your proxy might be blocking Apple's signature check for installing custom enterprise apps on iOS. Apple has recently started rolling out a new signature verification and PPQS check for new prov. profiles and our new accounts. During installation, Apple sends an initial API request to verify the signature of the app.

We recommend that you try the following workaround:

1. Disable the proxy for the device you are using to install the app.
2. If the above solution does not work, try using a different network without the proxy.

We do not have control over Apple's signature verification process. It is recommended to work with your network administrator to ensure that Apple's signature check is not blocked by the proxy.
