Maybe the Xcode team is using some special flags for compilation or applying internal fixes? I ask this question because we're seeing some projects that compile fine with the official toolchain, but fail to do so with one downloaded from the repository, from the exact tagged version.</div><div id="yui_3_16_0_ym19_1_1475490137083_2485" dir="ltr" class="" style="font-size: 12px;"><br class=""></div><div id="yui_3_16_0_ym19_1_1475490137083_2485" dir="ltr" class="" style="font-size: 12px;">Before we investigate this further, is it possible to create an "official" Swift toolchain using the build scripts (for internal use, I assume we cannot upload to the Store with that toolchain)?
