Hi Mustafa,
The issue only appears for touch scrolling events. The scrollContainer's vertical scrolling does work on desktops & android devices but fails on ios devices.On desktop & android scrollbars appear & scrolling is possible, but ios does not have scollbars & touch-drag scrolling doesn't work. It is the same with sap.m.Page. It does not seem to be a UI5 issue rather I perceive it to be a Design Studio issue which seems to suppress touch-drag events, as touch scrolling does not work even for scrollable content inside a Panel component.
Regards,
Stephen
