Failed to parse font key token
is displayed at console.
It doesn't particularly cause crashes, UI bugs, etc., but it is a concern.
This is occurred when I zoom on SwiftUI Map.
Part of code
struct MapView: View {
var body: some View {
Map(coordinateRegion: $viewModel.region,
showsUserLocation: true,
annotationItems: viewModel.pins,
annotationContent: { item in
MapAnnotation(coordinate: item.coordinate, anchorPoint: CGPoint(x: 0.5, y: 0.5), content: {
pinButton(pin: item)
})
})
.ignoresSafeArea()
}
}
My project is here.

I wrote as follows.
An error occurred on line 14 because of forced unwrapping.
extension SignInViewController: ASAuthorizationControllerDelegate {
@available(iOS 13.0, *)
func authorizationController(controller: ASAuthorizationController, didCompleteWithAuthorization authorization: ASAuthorization) {
var name: String? = nil
if let appleIDCredential = authorization.credential as?
ASAuthorizationAppleIDCredential {
if let fname = appleIDCredential.fullName?.familyName { name = fname }
if let gname = appleIDCredential.fullName?.givenName {name = name == nil ? gname : name!+gname}
authenticateWithApple(token:
appleIDCredential.identityToken?.toString, code: appleIDCredential.authorizationCode?.toString, name: name)
}
}
func authenticateWithApple(token: String?, code: String?, name: String?) {
authenticationScenario.signOut(from: .apple)
let param = [LQAAccountAppleTokenKey:token!, LQAAccountAppleAuthorizationCode:code!]
...
}
}
I fixed it by rewriting as below, but I would like to know why nil is included in identityToken or authorizationCode.
guard let identityToken = appleIDCredential.identityToken, let idTokenString = String(data: identityToken, encoding: .utf8) else { return }
guard let authorizationCode = appleIDCredential.authorizationCode, let authCodeString = String(data: authorizationCode, encoding: .utf8) else { return }
private func setupCollectionView() {
let registration = UICollectionView.CellRegistrationUICollectionViewListCell, Article { cell, _, item in
var content = cell.defaultContentConfiguration()
content.text = "title"
cell.contentConfiguration = content
}
XCTAssertEqual(cell.contentConfiguration.text, "title")
but
Value of type 'UIContentConfiguration?' has no member 'text'
Why does 'UIContentConfiguration?' have no member 'text' ??
