Hello,
I am getting following errors in Xcode console when running my app on the simulator with iPad Pro 13-inch (M4) 17.4:
CoreUI: _Bool CUIValidateIdiomSubtypes(NSInteger, NSUInteger *) passed a device subtype '2752' and idiom '2':pad that are not a matching pair, subtype is not valid with given idiom. Assuming subtype should be 0 instead.
This is the code:
import Foundation
import SwiftUI
struct PrefersTabNavigationEnvironmentKey: EnvironmentKey {
static var defaultValue: Bool = false
}
extension EnvironmentValues {
var prefersTabNavigation: Bool {
get { self[PrefersTabNavigationEnvironmentKey.self] }
set { self[PrefersTabNavigationEnvironmentKey.self] = newValue }
}
}
#if os(iOS)
extension PrefersTabNavigationEnvironmentKey: UITraitBridgedEnvironmentKey {
static func read(from traitCollection: UITraitCollection) -> Bool {
return traitCollection.userInterfaceIdiom == .phone || traitCollection.userInterfaceIdiom == .pad || traitCollection.userInterfaceIdiom == .tv
}
static func write(to mutableTraits: inout UIMutableTraits, value: Bool) {
// do not write
}
}
#endif
I am using this to decide what layout of the app to use – learned this from the Apple sample app Backyards Birds:
if prefersTabNavigation {
AppTabView(selection: $selection)
} else {
NavigationSplitView {
AppSideBar(selection: $selection)
} detail: {
AppDetailColumn(screen: selection)
}
}
Could you please help me find out what is wrong with the code?
