I have a struct that need to present some view when variable in class changes.
Example:
struct Example: View {
@StateObject var isText = ProviderDelegate()
var body: some View {
Text("here some text")
if(isText.show) {
Bar()
}
}
the providerDelegate:
class Adapter: ObservableObject {
@Published public var show: Bool = false;
func changeShow() {
show.toggle()
}
...
}
when function from other class to changeShow the View is not updation, thus the bar() is not shown.
Why is that?

Hey,
I don't know why i can not make scan function work.
I have written in the entitlement file:
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>com.apple.developer.nfc.readersession.formats</key>
<array>
<string>NDEF</string>
<string>TAG</string>
</array>
</dict>
</plist>
also in the info.plist:
<key>com.apple.developer.nfc.readersession.iso7816.select-identifiers</key>
<array>
<string>A0000002471001</string>
<string>D2760000850101</string>
<!-- Add more AIDs as needed -->
</array>
still get the error Error Domain=NFCError Code=2 "Missing required entitlement"
of course when i remove the iso18092 enum everything is working.
Help? thanks
