SWF and AE are not the same kind of apps at all. SWF and flash as it was known are not compatible with 90% of mobile devices. Flash has been completely re-engineered as an interactive animation app compatible with HTML 5 and mobile devices. When AE did support exporting SWF files it didn't work very well, almost all effects had to be rasterized and the SWF files were huge and didn't play well with other objects in a Flash/Swf format.
If you are delivering SWF files to a client now you are delivering obsolete product and doing a disservice to your clients. You should check out Animate CC (the new Flash) and rethink your workflow.
