Xcode 11 beta 4 compiler error

[alandeguz]

Steps to reproduce

• Using Xcode 10.2.1, create brand-new project (single view app, I named mine Test01).
• Configure Test01 to target iOS 11.
• Quit Xcode 10.2.1
• Using latest Cocoapods tool (1.7.2), enable pods with Reusable 4.1.0 as the sole dependency (see Podfile.txt).
• Open Xcode 10.2.1, and verify compiling the project workspace (Test01.workspace).
• Quit Xcode 10.2.1
• Start Xcode 11.0 beta 3, and verify compiling the project workspace.
• Quit Xcode 11.0 beta 3
• Start Xcode 11.0 beta 4, and verify compiling the project workspace

Expected behavior

• Compile with no error

Actual behavior

• The project won't compile (see xcode.error.txt).

Notes

• I discovered this issue when testing Beta 4 (released July 17th) on my current project, and validated that this compiler error happens with a brand-new project as well.
• I manually clear my DerivedData folder (delete it via bash script) every time before I startup a different version of Xcode.

This isn't a Reusable issue... it's a Cocoapods issue. I'm closing this.
