At first you should know, that the splash screen is just a static image, you can set it by this step:

1 Create a single view application:

2 Going to "info.plist" you can find "launch images", click "Use Asset Catalog":

3 Then remove the "LaunchScreen.storyboard" from your solution, and remove the Key "Launch screen interface file base name" from the info.plist->source:

4 At last set the image you want in "Assets.xcassets":

Oh, another thing, if you need change anything in "Assets.xcassets" you'd batter:

1 Clean your solution and rebuild it;

2 Delete the APP from your device if you already install the old one;

3 Then install the new one, it will works.

Hope it can help you.

Add one xib file and setup your launch screen image in that xib file with UIImageview, and then assign that file to"Launch Screen File" Check attached screenshot for help.

Hope this helps!

Make sure you are connected to your external Mac. Then double click Launchscreen.storyboard in your iOS-project. You should get a design-view of the Splashscreen.

If you want to put a image to fill any screen size without open Xcode:

Go to your Resources -> LaunchScreen.storyboard file

• Right click to your "LaunchScreen.storyboard" file -> Open Width -> Source Code Editor

Replace your Storyboard code with the following:

<?xml version="1.0" encoding="UTF-8"?>

                                <autoresizingMask key="autoresizingMask" widthSizable="YES" heightSizable="YES"/>
                            </imageView>
                        </subviews>
                        <color key="backgroundColor" red="0.20392156862745098" green="0.59607843137254901" blue="0.85882352941176465" alpha="1" colorSpace="custom" customColorSpace="sRGB"/>
                    </view>

                <placeholder placeholderIdentifier="IBFirstResponder" id="XAI-xm-WK6" userLabel="First Responder" sceneMemberID="firstResponder"/>
            </objects>
            <point key="canvasLocation" x="348" y="338.68065967016497"/>
        </scene>
    </scenes>
    <resources>
        <image name="background1.png" width="2560" height="1600"/>
    </resources>
</document>

• Where you see "background1.png" put the name of your background resource image file that should be located in the Resources Folder of your Xamarin.ios project.
