Version History

1.10.0 July 27 2108

  • Rebuilt with XCode 8.2.1 on macOS Sierra
  • Proper error message if Adobe Flash Plugin is not installed.
  • Technically it can be almost approved to the Mac App Store, but since the most important feature uses the Adobe Flash Plugin, it is not worthy (Makes sense - maybe I should redo iSwiff as a way to extract media from SWF files instead making it possible to bring the contents forward. And since most use iSwiff to play video or view slides, that use is good).

1.1 May 6 2005

Update for Tiger and MacOS 10.3.9. Added the ability to play flash files through Personal Web sharing.  Some files don't play directly from hard disk, but need to be played form a server.
You can do this on your Mac by:
  1. Enable Personal Web sharing in System Preferences.
  2. Place the flash files in your "Sites" folder. 
When iSwiff opens files in your "Sites" folder it will open them through your web server, and they may fullfill the need to be network played. Some games have stronger requirements than this, and they can only be played from the website where they reside.

1.0.3 February 26 2005

  • Fixes of several user interface issues.

1.0.2 January 5 2005
  • Can now open files with unicode names
1.0.1 January 5 2005
  • Window resize problem fixed
1.0 January 3 2005
  • First release


You can try it from the disk image, and if you link it you can drag to your "Applications" Folder, or anywhere on your hard disk.


Drag iSwiff to the trash.


Drop Flash files on iSwiff or open then from the File menu.
