TiApp Editor lists the installed SDKs in strict alphabetical order. However this does not show the true prominence of the choices.
- 3.5.0 RC
- 3.5.0 GA
- 3.5.0 Beta
- 3.4.1 GA
With 3.5.0 RC displayed first it appears as the newest or "more" correct SDK. However "3.5.0 GA" is the correct choice from the "3.5.0 xx" family.
Having created a new project the SDK selected as 3.5.0 RC rather than 3.5.0 GA. Whilst there are CLI ways to set the default SDK, there are no immediately obvious (near the selection itself) ways to set that default through Ti Studio.
So I assume the default choice is made from the most alphabetically highest value rather than the true most suitable or most recent.
