Yes, there are many of us that have extensive experience with both Python and Swift, and many more who have experience with Python libraries that want to write their code in Swift because it fits better with some other part of their project. Maybe not because they want to desert Python, and maybe not because they love Swift, but because it's a better way to solve that particular problem. Before Swift existed, I wrote high-level parts of a project in Python because it was untenable to do it in Objective-C (it was actually much easier for me to write a bridge *and* the Python code than to write it in Objective-C), but now I have rewritten those parts in Swift, because I could throw out the Python runtime and write interface code and logic code in the same language. I didn't depend on any critical Python libraries, but others will, and if they want to write Cocoa code in Swift, they have to have a Python bridge, and the probability that a high-quality Python bridge will exist is much lower if the syntax is awful. This of course goes for other dynamically typed languages as well. /Magnus _______________________________________________ swift-evolution mailing list swift-evolution@swift.org https://lists.swift.org/mailman/listinfo/swift-evolution
