I started a large solo project in late 2019 using Swift. I have no trouble compiling and linking the project today. I have been adding Swift code to an old Objective-C project without issues. There was an open source objc project I tried to modify recently, and was told that a feature was so deprecated that using it was no longer an option, forcing me to consider rewriting a large swatch of objc code; it just got so convoluted that I bailed.
