When I try to open file open or file save dialog inside Xcode is sliding down from the top.
Which XCode version ?
I tested the following in XCode 10.2.1:
- open a project
- call open… from File menu
The panel opens in the middle of the screen, directly, not sliding from top.
Can you describe how you get the sliding effect in XCode ?
Do you see the same sliding effect in other apps ?
I have Xcode 9 and in there when I select "File->Duplicate... the panel slides from the top.
But "File->Open does come from the middle of the screen.
Sorry about the confusion.
The "runModal" methods create an independent window, which gets a standard window opening animation. Panels that slide down from the top are actually sheets, and you get them by using the "beginSheet" variants of the methods:
