I am using MATLAB R2016b on a Mac. I have tried the following which results in a black box with the specified dimensions (640x480) showing up in the UIAxes:
vid = videoinput('macvideo', 1);
hImage = image(app.UIAxes1, zeros(640,480,3));
preview(vid, hImage);
I get this error message:
Error using imaqdevice/preview (line 176)
There is no ALimMode property on the UIAxes class.
Is preview not supported in App Designer yet?

The Image Acquisition Toolbox PREVIEW function does not support UIAXES in R2016b yet, but the toolbox team is aware of the customer need.

I do not know if this works in 2016. But try this.
hf_Preview = figure('Toolbar','none',...
'Menubar', 'none',...
'NumberTitle','Off',...
'Name','Preview Window');
ha = axes(hf_Preview);
vid = videoinput('macvideo', 1);
hImage = image(zeros(640,480,3), 'Parent', ha);
preview(vid, hImage);
