ios - App Transport Security has blocked a cleartext HTTP resource

Question

I am using Socket.IO library in swift and I keep getting this error:

App Transport Security has blocked a cleartext HTTP (http://) resource load since it is insecure. Temporary exceptions can be configured via your app's Info.plist file.

when I am trying to send an http request. I added the keys to plist according to the official apple documentation, but it did not help.

You need to correct it like this:

To make it easier, this is the correct xml in the info.plist

<key>NSAppTransportSecurity</key>
    <dict>
        <key>NSExceptionDomains</key>
        <dict>
            <key>localhost</key>
            <dict>
                <key>NSIncludesSubdomains</key>
                <true/>
                <key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
                <true/>
                <key>NSTemporaryExceptionMinimumTLSVersion</key>
                <string>TLSv1.1</string>
            </dict>
        </dict>
    </dict>

change the localhost to your actual server

Check the table for NSAppTransportSecurity options

If you want to all communications with any domain, you can do this:

 <key>NSAppTransportSecurity</key>
    <dict>
        <key>NSAllowsArbitraryLoads</key>
        <true/>
    </dict>

However, you should use the latest just in the developing phase.
