I propose fix to avoid null failure on iPhone 5

##- OBS 1

• When compiling the application and generating the error below in the ModernSearchBar.swift file in the updateSizeSuggestionsView () method
  updateSizeSuggestionsView()

private func updateSizeSuggestionsView(){
    var frame: CGRect = self.suggestionsView.frame
    frame.size.height = self.getExactMaxHeightSuggestionsView(newHeight: self.suggestionsView.contentSize.height)

    UIView.animate(withDuration: 0.3) {
        self.suggestionsView.frame = frame
        self.suggestionsView.layoutIfNeeded()
        self.suggestionsView.sizeToFit()
    }
}

• Corrigir assim: (veja que foi adicionado um if para evitar objeto nulo)

private func updateSizeSuggestionsView(){
    if(suggestionsView != nil){
        var frame: CGRect = self.suggestionsView.frame
        frame.size.height = self.getExactMaxHeightSuggestionsView(newHeight: self.suggestionsView.contentSize.height)

        UIView.animate(withDuration: 0.3) {
        self.suggestionsView.frame = frame
        self.suggestionsView.layoutIfNeeded()
        self.suggestionsView.sizeToFit()
        }
    }
}
