in exercise https://github.com/Mairoslav/5networkAndGDC/tree/main/ImageRequest I would like to allow the jpg to be loaded from the web site with "http" scheme by adjusting NSAppTransportSecurity in Info.plist as written below. I do not want to allow any other "http" sites, therefore opted to set NSAllowsArbitraryLoads to false. If you can advice.
<dict>
<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key>
<false/>
<key>NSExceptionDomains</key>
<dict>
<key>www.kittenswhiskers.com</key>
<dict>
<key>NSIncludesSubdomains</key>
<true/>
<key>NSExceptionAllowsInsecureHTTPLoads</key>
<true/>
<key>NSExceptionMinimumTLSVersion</key>
<string>TLSv1.0</string>
<key>NSExceptionRequiresForwardSecrecy</key>
<false/>
</dict>
</dict>
</dict>
Even after these adjustments, there is an error: "The resource could not be loaded because the App Transport Security policy requires the use of a secure connection." I have tried all alternative options for NSExceptionMinimumTLSVersion. The sources I was using were: https://agilie.com/blog/how-to-add-domain-exceptions-to-comply-with-apples-new-ats-requirements, https://cocoacasts.com/how-to-add-app-transport-security-exception-domains and https://developer.apple.com/documentation/bundleresources/information_property_list/nsapptransportsecurity
Here is my test code and Info.plist
, that works well for me. Tested on real devices, not Previews.
The Info.plist
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key>
<false/>
<key>NSExceptionDomains</key>
<dict>
<key>www.kittenswhiskers.com</key>
<dict>
<key>NSIncludesSubdomains</key>
<true/>
<key>NSExceptionAllowsInsecureHTTPLoads</key>
<true/>
<key>NSExceptionMinimumTLSVersion</key>
<string>TLSv1.0</string>
<key>NSExceptionRequiresForwardSecrecy</key>
<false/>
</dict>
</dict>
</dict>
</dict>
</plist>
The test code
struct ContentView: View {
@State var image = UIImage()
var body: some View {
Image(uiImage: image)
.resizable()
.aspectRatio(contentMode: .fit)
.frame(width: 333, height: 333)
.cornerRadius(10)
.task {
if let url = URL(string: "http://www.kittenswhiskers.com/wp-content/uploads/sites/23/2014/02/Kitten-playing-with-yarn.jpg") {
image = await loadImage(url: url)
}
}
}
func loadImage(url: URL) async -> UIImage {
do {
let (data, _) = try await URLSession.shared.data(from: url)
if let img = UIImage(data: data) { return img }
}
catch { print(error) }
return UIImage()
}
}
