Importing Cocoa SDKs
Usually, imports for new versions of Xcode, including betas, are made available within a day or two at elementscompiler.com/elements/sdks, so you will rarely have the need to import SDKs yourself.
That said, FXGen integrated into Fire makes it possible to use beta SDKs we haven't added support for yet, or to manually re-import an existing SDK (e.g. older) SDK, should the need arise.
FXGen for Cocoa SDKs is available via the "Tools|Cocoa|FXGen|Import SDKs from Xcode" menu. Selecting the command will show the following sheet:
Fire will already pre-select the currently active Xcode version (if configured), but you can select a different (e.g. older) version of
Xcode.app via the "Browse" button at the top.
In the table view below, FXGen shows all the SDKs found in Xcode, and it will check the ones that Fire does not already have
.fx files for by default. You can also optionally check SDKs marked as "(already imported)", if you want to to re-import them anyway.
Click "Import" to start the import process, and FXGen will launch the import script and show the "Activity" window, where you can see progress,
Depending on the size and scope of the SDKs, this can take several mintes or longer; you can close the FXGen sheet and continue working, om the mean time.
The SDKs generate a lot of .fx files, for some platforms in up to five different architectures. iOS for example generates
arm64 versions for the device, which will then be merged to a Universal
x64 version for the Simulator, which also will be merged. macOS generates only one architecture, but has well over 100 different framework files, from
WebKit.fx, and each new version adds more.
