iPad Multitasking support requires these orientations

iPad Multitasking support requires all the orientations but your app does not, so you need to opt out of it, just add the UIRequiresFullScreen key to your Xcode project’s Info.plist file and apply the Boolean value YES.

In Xcode, check the "Requires Full Screen" checkbox under General > Targets, as shown below.

I am using Xamarin and there is no available option in the UI to specify "Requires full screen". I, therefore, had to follow @Michael Wang's answer with a slight modification. Here goes:

Open the info.plist file in a text editor and add the lines:

<key>UIRequiresFullScreen</key>
<true/>

I tried setting the value to "YES" but it didn't work, which was kind of expected.

In case you are wondering, I placed the above lines below the UISupportedInterfaceOrientations section

<key>UISupportedInterfaceOrientations~ipad</key>
<array>
    <string>UIInterfaceOrientationPortrait</string>
    <string>UIInterfaceOrientationPortraitUpsideDown</string>
</array>

Hope this helps someone. Credit to Michael.

as Michael said,

Check the "Requires full screen" of the target of xcodeproj, if you don't need to support multitasking.

or Check the following device orientations

Portrait

Upside Down

Landscape Left

Landscape Right

In this case, we need to support launch storyboard.

Unchecked all Device orientation and checked only "Requires full screen". Its working properly

Go to your project target in Xcode > General > Set "Requires full screen" (under Hide status bar) to true.

As Michael said check the "Requires Full Screen" checkbox under General > Targets

and also delete the 'CFBundleIcons-ipad' from the info.plst

This worked for me

You need to add Portrait (top home button) on the supported interface orientation field of info.plist file in xcode
