@ObservedObject 带有属性初始化器 - SwiftUI

Question

I have this code:

struct TestView: View {

    lazy var currentCompetitionID: String

    @ObservedObject var fetchSingleCompetitionData = FetchSingleCompetitionData(option: "\(currentCompetitionID)")

    var body: some View {
       Text("\(fetchSingleCompetitionData.competitionList.name)")
    }
}

I receive the error: "Cannot use instance member 'currentCompetitionID' within property initializer; property initializers run before 'self' is available"

Is there any way to initialize and use variable in the same view? Thank you!

Answer 1

fetchSingleCompetitionData is being initialized as part of init . Lazy vars are only available afterwards. Consider moving the initialization to a fully-qualified initializer.
