It doesn't work on iOS.

I have an issue; my code works perfectly on Android but not on iOS, and it gives me this in Xcode console
"Request to remove background on an unsupported device. Error Domain=com.apple.VisionKit.RemoveBackground Code=-8 "(null)"
MADService: VisualSearchGating: Could not get visual search result from MADService with Error Domain=VisualIntelligence.FlowError Code=1 "(null)" "
