50347914: Bundle.main returns the wrong bundle inside a framework

[openradar-mirror]

Description

Summary:

 Bundle.main inside a framework returns the wrong data.

 [From the docs:](https://developer.apple.com/documentation/foundation/bundle/1410786-main)
 "_For code running in a framework, the main bundle offers access to the framework’s bundle directory_."

 However, when breaking in the provided test method, the main bundle is referring to Xcode:

 ```
 (lldb) po Bundle.main
 NSBundle </Applications/Xcode-10.1.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/Library/Xcode/Agents> (loaded)
 ```

 I would expect the frameworks bundle here.

Steps to Reproduce:

• run the test

Expected Results:

• The test is green, the frameworks bundle is returned by .main

Actual Results:

• The test fails, because the bundle of Xcode is returned

Version/Build:

Xcode 10.2.1 (10E1001)

Configuration:

osx 10.14.4 (18E226)
