Autogenerated file gets regenerated at every build causing submodule to become dirty

[c0diq]

Describe the bug Everytime RxBluetoothKit is built from scratch, the file Tests/Autogenerated/_Peripheral.generated.swift seems to be regenerated and looks different causing the git submodule to become dirty.

To Reproduce Steps to reproduce the behavior:

1. Add RxBluetoothKit as submodule
2. Build RxBluetoothKit
3. Notice Tests/Autogenerated/_Peripheral.generated.swift changes

Expected behavior Tests/Autogenerated/_Peripheral.generated.swift shouldn't change or be git ignored.

Environment:

• Library version [5.1.3]
• Swift version [4.1]

A fix is to remove gsed from environment but is not very nice.

Can we use an environment variable and execute code generation using a script instead of a build phase?
