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?
In SwiftUI, I have several TextFields in a Form and they always begin with initial caps when data is entered? How do I prevent this? I want the field to be all lowercase.
This code worked in Xcode 12.0 B1 but no longer works in B2.
struct ContentView: View {
var body: some View {
NavigationView {
List {
ForEach (1..<10) {
row in
Text("\(row) - Test").foregroundColor(Color.white).fontWeight(.bold)
}
.listRowBackground(Color.burgundy)
}
.navigationTitle(Text("List Background Color Test"))
.navigationBarTitleDisplayMode(.inline)
.toolbar {
ToolbarItem(placement: .bottomBar) {
HStack {
Button(action: {}, label: {
Text("One").foregroundColor(Color.white)
})
Spacer()
Button(action: {}, label: {
Text("Two").foregroundColor(Color.white)
})
Spacer()
Button(action: {}, label: {
Text("Three").foregroundColor(Color.white)
}).foregroundColor(.blue)
}
}
}
}
}
}

I have this code giving me the deprecated warning. How do I fix this?:
// Retrieve the unscanned remainder of the string
if textScanner.scanLocation < textScanner.string.count {
textToScan = (textScanner.string as NSString).substring(from: textScanner.scanLocation + 1)
}
