MATLAB: Is app designer not opening

app designer

I am unable to open app designer. I am running Mac OS Sierra with MATLAB 2016b. When I click on opening a new app designer script a MATLAB window icon appears in my dock, but a window does not appear.

I was having the exact same problem (2016b, OS Sierra), which appeared when I had entered full-screen mode while connected to projector. In MATLAB click on new app designer script or open existing mlapp file, icon should appear in the dock. Then Menu->Enter full screen, app designer will show up, if not, swipe on your trackpad until designer window pops out, then reset it by closing MATLAB Window from the top menu. Worked in my case. Btw I tried changing the matlabpref.mat as suggested by Sean, it did not work itself, but there still might be a correlation with my solution as I didn't change the setting back.

MATLAB: Appdesigner startup in editing mode

A possible workaround for this issue is to regenerate the MATLAB preferences directory and then try launching App Designer again as normal.

For instructions on regenerating the MATLAB preferences directory, please refer to the MATLAB Answers post below:

MATLAB: Appdesigner window ends up in background after uigetfile

For MATLAB R2018a and newer you can use the figure command to focus your app again,

uigetfile; % Could be other dialogs here

drawnow;
figure(app.UIFigure)

For releases prior either turn the visibility off and on again or use the attached p file (change extension from .zip to .p). The usage then would be

uigetfile; % Could be other dialogs here
drawnow;
FocusUIFigure(app.UIFigure)
