This code:

Section { Text("((Double(self.conversion[self.startUnits[self.startUnit]] ?? 1) / (self.conversion[self.targetUnits[self.targetUnit]] ?? 1) * self.startAmount), specifier: "%.2f")")

triggers this error message: "The compiler is unable to type-check this expression in reasonable time; try breaking up the expression into distinct sub-expressions".

How does one do this? Apparently cannot declare variables within the body view and cannot do it before then either because user input is needed.

HI Chris

Have you looked at the other posts for this topic:

https://www.hackingwithswift.com/forums/100-days-of-swiftui/day-19-challenge-day/604

https://www.hackingwithswift.com/forums/swiftui/project-2-day-19/1015

Regards Tim.

Tim,

No, I have not looked at those because I did not know they existed which raises a new question: How does one search for such posts? When I type in key words on this page's search field, such as "Day 19", I get a barrage of links to random articles. When I browse the topic lines of the "100 Days of SwiftUI", the one you referenced does not appear. Further, I would have never thought to browse the SwiftUI forum, but now I at least know that much.

Thank you!

Chris

Hi Chris,

Yes Paul's site is a great resource, however you can't beat the king of search so I always head to google, I searched for:

"Day 19 challenge swiftui forums"

I do the same for other sites like stackoverflow or even apple.

Regards, Tim.
