MaxDesiatov · web-flow · commit 2b5857b0c93c · 2022-01-10T08:10:25.000Z
Currently, when trying to build with the latest stable Xcode, you get this error:

```
using unsupported Xcode version:

Xcode 13.2.1
Build version 13C100
```

Xcode 13.2.1 can successfully build the toolchain and should be marked as supported.
