Hi,

I'm trying to convert a "regular" FAT Framework to a XCFramework to make later use of it in the Swift-Package Manager (SPM).

This process works with very simple framework which has just a struct with one string property and a function.

But when I'm try to convert a more complex framework, like SwiftyBeaver, I get a kinds of weird errors as soon as I try to import the XCFramework in my project.

The error message in the Xcode-IDE is:

**"Failed to build module 'SwiftyBeaver' for importation due to the errors above; the textual interface may be broken by project issues or a compiler bug"**

When I look into the **arm64-apple-ios.swiftinterface** - file I see all kind of weird declerations like:

```swift
open class BaseDestination : Swift.Hashable, Swift.Equatable {
  open var format: Swift.String
  open var asynchronously: Swift.Bool
  open var minLevel: SwiftyBeaver.SwiftyBeaver.Level
  open var levelString: SwiftyBeaver.BaseDestination.LevelString
  open var levelColor: SwiftyBeaver.BaseDestination.LevelColor
  open var calendar: Foundation.Calendar

```

and error messages like: **SwiftyBeaver' is not a member type of class 'SwiftyBeaver.SwiftyBeaver**'

Which is very likely true.

These are the commands I execute to create the XCFramework:

`xcodebuild archive -scheme SwiftyBeaver -destination "generic/platform=iOS" -archivePath /work/SwifyBeaver.xcarchive SKIP_INSTALL=NO BUILD_LIBRARY_FOR_DISTRIBUTION=YES`

ARCHIVE SUCCEEDED

and then:

`xcodebuild -create-xcframework -framework /work/SwifyBeaver.xcarchive/Products/Library/Frameworks/SwiftyBeaver.framework -output ./SwiftyBeaver.xcframework`

both commands succeed but when I add the XCFramework to my XCode-Project and import the module I get error message - stated above:

**"Failed to build module 'SwiftyBeaver' for importation due to the errors above; the textual interface may be broken by project issues or a compiler bug"**

I'm using XCode 13.3.1 and xcodebuild -version gives me this output:

```swift

Any idea how to solve this problem?

Thanks in advance!
