The swift compiler, as a recursive descent parser is terribly slow at resolving broken code. It really needs to be replaced with an LALR1 compiler using lex/yacc with the swift syntax more fully described in the grammar instead of their being so much context sensitive choices that require the compiler to unwind and recompile from so many different levels to try and discern what is meant by the content.
Modern day compilers should be complaining about syntax errors much more quickly. Certainly named parameters make it a lot harder to "figure out" the polymorphic resolve of the exact method. But realistically I am having to wait 5min or more for some problems that are only reported as
"The compiler is unable to type-check this expression in reasonable time; try breaking up the expression into distinct sub-expressions"
The SwiftUI chaining of .onChange(), and other things with code in them create the biggest barrier here. Something different needs to happen here that moves the base syntax resolution to happen first and then have polymorphic binding result methods. That may already be what's being done, I don't know, but I just am spending day after day commenting out lines of code trying to find the syntax error and get a real error message. It's keeping me from being productive and pushing me to just stop and give up again on these apps I keep trying to put together but have to rewrite because each time I try again, I have a complete new set of APIs, language, libraries etc. to deal with.
