XCTEST_UI_TEST_PACKAGE_UNZIP_FAILED

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

Warning

We could not open your test IPA file. 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 swift-sample-UI.ipa.

Copy your test package to your working directory, and then run the following command:
```
$ unzip swift-sample-UI.ipa
```

                      |       `swift-sampleUITests.xctest (directory)
                      |                       |-- Info.plist
                      |                       `-- (any other files)
                      `-- (any other files)

To find the executable value, you can open Info.plist using Xcode or Python.

For Python, you can install the biplist module by running the following command:
```
$ pip install biplist
```

Next, open Python and run the following command:


import biplist
info_plist = biplist.readPlist('Payload/swift-sampleUITests-Runner.app/Plugins/swift-sampleUITests.xctest/Info.plist')
print info_plist['CFBundleExecutable']

A valid XCtest UI package should produce output like the following:


swift-sampleUITests
