Xib2Nib.exe failure should not be fatal

[alakoring]

  Unable to find class mapping for required object <visualEffectView>
C:\WinObjC\msvc\sbresources.targets(174,5): error MSB3073: The command ""C:\WinObjC\msvc\..\bin\Xib2Nib.exe" "..\..\Resources\Base.lproj\DebugDialog.xib" "Debug\Base.lproj\DebugDialog.nib"" exited with code -1.

I realize this is nearly a duplicate of #367 but it would be more useful if I got a runtime crash instead of being able to see how well the bridge works for all the other views in my app. (Probably poorly because I also use UIStackView, but I'd love to see something show up to know if it’s worth continuing down the WinObjC path.)

Thank you for the feedback. Would you be able to share the list of controls you're using in your xib files and storyboard and we can tell you which one will cause problem with Xib2Nib? We did "stub" some of the unsupported control in Xib2Nib to avoid this but we did not do that for all of them.

Oops, I didn't realize that GitHub didn't show the actual class: it's UIVisualEffectView. I don't have a great way to catalog the UIKit classes I use, especially since I don't even know how to exclude this from the build to get to the next error.

(Oh, at least it's just the project, I was afraid there was some other mapping file created by the converter.)

So my next error from Xib2Nib is worse:

Unable to find class mapping for required object <nil>

I wonder if this was an Interface Builder bug?

                        <label opaque="NO" userInteractionEnabled="NO" contentMode="left" horizontalHuggingPriority="251" verticalHuggingPriority="251" text="Sacred Time" lineBreakMode="tailTruncation" baselineAdjustment="alignBaselines" adjustsFontSizeToFit="NO" translatesAutoresizingMaskIntoConstraints="NO" id="ijC-2a-i2C" customClass="SmallCapsLabel">
                            <rect key="frame" x="0.0" y="0.0" width="96.5" height="20.5"/>
                            <fontDescription key="fontDescription" type="system" pointSize="17"/>
                            <color key="textColor" red="0.0" green="0.0" blue="0.0" alpha="1" colorSpace="custom" customColorSpace="sRGB"/>
                            <nil key="highlightedColor"/>
                        </label>

I manually removed any <nil …> lines and proceeded.
