QQ: Does pod install --clean-install ignore the Podfile.lock file? The documentation is unclear.
--clean-install
Ignore the contents of the project cache and force a full pod installation. This only applies to projects that have enabled incremental installation.

No, the documentation says that it will ignore the cache which means it will download pod from Remote instead of using cache from your machine.
If you want to ignore the Podfile.lock file then just rename it (may be Podfile1.lock) or remove it and run pod install.
