Can't edit Info.plist (read/write permission) in XCODE 7

Question

I'm trying to solve the issue mentioned here .

I found a solution: edit my info.plist.

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSExceptionDomains</key>
    <dict>
        <key>mydomain.com</key>
        <dict>
            <key>NSIncludesSubdomains</key>
            <true/>
            <key>NSExceptionAllowsInsecureHTTPLoads</key>
            <true/>
            <key>NSExceptionRequiresForwardSecrecy</key>
            <false/>
        </dict>
    </dict>
</dict>

I tried to edit every way I could think of (Textedit, xml edit, open as source code, etc.). I even tried to do it manually with raw values, but every time I try to save it, it freezes.

Why is this happening, and how can I fix it?

my info Plist

Answer 1

At the end you can add like this.. this resolves you.

<key>UISupportedInterfaceOrientations</key>
<array>
    <string>UIInterfaceOrientationPortrait</string>
    <string>UIInterfaceOrientationLandscapeLeft</string>
    <string>UIInterfaceOrientationLandscapeRight</string>
</array>
<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
</dict>
