SwiftUI – Change TabBar Icon Color

Solution 1

Use renderingMode(.template)

struct MainView: View {

    var body: some View {
       TabView {
            LoginView().tabItem {
                VStack {
                    Text("Login")
                    Image("login").renderingMode(.template)
                }
            }

            HomeView().tabItem {
                VStack {
                    Text("Home")
                    Image("home").renderingMode(.template)
                }
            }
        }.accentColor(.orange)
    }
}

Solution 2

Make tabItem type

enum TabViewItemType: String {
    case login  = "login"
    case home   = "home"
    case search = "search"

    var image: Image {
        switch self {
        case .login:  return Image("login")
        case .home:   return Image("home")
        case .search: return Image("search")
        }
    }

    var text: Text {
        Text(self.rawValue)
    }
}

struct MainView: View {

    var body: some View {
        TabView {
            LoginView()
                .tabItem { TabViewItem(type: .login) }

            HomeView()
                .tabItem { TabViewItem(type: .home) }

            SearchView()
                .tabItem { TabViewItem(type: .search) }

        }.accentColor(.orange)
    }
}

struct TabViewItem: View {

    var type: TabViewItemType

    var body: some View {
        VStack {
            type.image.renderingMode(.template)
            type.text

        }
    }
}
