Hi,
Well, it's software, so both are likely to have bugs. IMO, the apps from XF folder seem to be more intuitive and easier to use.
- The folders <SDK>/sw/{android, ios, macos}/tlogger are examples of host applications that implement a GUI and the communication protocol on top of the NDEF messaging in a dedicated language, for a dedicated platform. This turned out to be maintenance burden.
- The folder <SDK>/XF/tlogger will replace all the dedicated host implementations. It provides projects to compile to Android, iOS, macOS and Win10. At this moment, these are still projects for MS VS 2017, but the next SDK will be updating that.
Plans for the next SDK (still a few months away):- Based on MS VS 2019
- Using iOS NFC write capability (new since iOS13)
- Bug fixes - as always
- Removal of Android, iOS, macOS specific code.
Btw, the current iOS and Android listings in the Play/App store are built using the XF code from the internal development branch.
BR,
Dries.
