SwiftUI Preset Picker
When I create a picker, for example font settings, it always show the values, but not with the last selected one preselected. How can I create a picker that has the last selected value shown selected the next time the view is viewed. I plan to store the last selected value in UserDefaults.Thank in advance for any help.

WKWebView in SwiftUI iOS 14 and Xcode 12
I have code that loads an HTML page into a WKWebView and needs to call javascript functions in the HTML page to update font family and size. Now that WKPreferences.javaScriptEnabled has been deprecated, it does not seem to work anymore. How to I correctly create a struct WebView: UIViewRepresentable with makeUIView and updateUIView to be able to show the page and call the functions in the HTML page? Please help...

SwiftData Predicate not working.
My predicate: #Predicate{ transaction in transaction.date! >= startDate && transaction.date! <= endDate && transaction.category! == "Income" && transaction.ttype! == "Business" } is failing with: The operation couldn’t be completed. (SwiftData.SwiftDataError error 1.) The release notes for iOS 17 State: Fixed: #Predicate does not support UUID, Date, and URL properties. (109539652) Does anyone have any suggestions?
