Reply to Returning Type Optional("Text") but I just want ("Text")

The Array.first function returns an optional value, because the array could be empty. You have to unwrap that.

Reply to Tasks shown "alive" in Instruments display even after they should have finished.

Unfortunately not, ... but yesterday I heard someone talk about retain cycles in SwiftUI and closures and now that you ask, this may actually be the problem here: Task's closure retains some values. Try using some weak captures could be the solution.

Reply to GeometryReader problem

Without seeing your code we can only speculate: It could be possible that the size is reported as beeing zero for a short period. Change your code to prevent using a size of zero and see if that solves the problem.
