Swift: #warning equivalent

Question

Does Swift have a #warning equivalent? It\'s simply used to show a warning in Xcode\'s own GUI

I\'m also interested in whether there\'s a #error equivalent.

Answer 1

We wrote a configurable tool that lets you put warnings and errors in Xcode Issue Navigator based on comment tag and build configuration: https://github.com/doubleencore/XcodeIssueGenerator

Install it:

brew tap doubleencore/tap
brew install xcodeissuegenerator

Then put a line in a Run Script Build Phase:

# Mark WARNINGs, SERIOUSs, and TODOs as warnings in DEBUG builds excluding the Vendor and Third Party directories.
XcodeIssueGenerator -b DEBUG -w "WARNING, SERIOUS, TODO" -x "Vendor/, Third Party/"

Here's an article describing how we use it.
