You can. But you can also use Avalonia*, Uno Platform* , Gir.Core or whatever currently maintained Qt binding library is for .NET. The FP and syntax advantages listed in the article exist in equal measure in C#, and so do zero-cost Rust-style abstractions. Swift is a language with a lot of potential, but it has a lot of work ahead of it, the work that was done for .NET's performance, cross-platform support, tooling ecosystem and OSS-focused development process. *both of which have SwiftUI style extensions for declarative UI definition and MVU patterns. Avalonia even has the F# version of that.
