If you are developing with Firestore, thanks to its complex functionalities, its hard to mock for testing.

Terraform has a concept called workspace. Creating one is quite simple, just run: terraform workspace new <your workspace name>

Terraform is a powerful infrastructure provisioning tool. It just reminds me how kubernetes impress me when I first learned it.

If you have written Swift, there is an extension pattern that is pretty neat and handy.

When writing software for production, inevitably you will have to write some unit tests to ensure the functionalities are working just fine in certain scenarios.
