Use new .onChange modifier with Picker

Forums > SwiftUI

I have a Picker setup as a segmented control which modifies a property in an environment object. When that property is modified, I would like to use the new .onChange modifier to set a local binding's value.

    @EnvironmentObject var tvm: TrucksViewModel
    @Binding var slideoverPosition: CGFloat

...

         //status picker
         Picker(selection: $tvm.status, label: Text("Status")) {
               Text("All").tag("All")
                Text("Scheduled").tag("Scheduled")
                Text("Live").tag("Live")
           }
           .onChange (of: tvm.status) {
                  pickerChanged()
            }
            .pickerStyle(SegmentedPickerStyle())

When I include the .onChange modifier I can't seem to figure out what the proper value of the of: parameter should be. I have tried tvm.status and $tvm.status but I keep getting an error like:

Cannot convert value of type 'String' to expected argument type '()'

Not sure how to fix this. Any help would be appreciated.

Solution found!

                        .onChange(of: tvm.status, perform: { (value) in
                            pickerChanged()
                        })
