fantastic, that's definitely a Swift/LLVM bug. From what I can see the most relevant bit is

--- SNIP ---
>   "output": "PHI node operands are not the same type as the result!\n  %384 = phi %CSo7UIColor* [ %395, %394 ], [ %377, %379 ], !dbg !469\nPHI node operands are not the same type as the result!\n  %395 = phi %CSo7UIColor* [ %349, %346 ], [ %377, %378 ], !dbg !469\nPHI node operands are not the same type as the result!\n  %738 = phi %CSo7UIColor* [ %749, %748 ], [ %731, %733 ], !dbg !517\nPHI node operands are not the same type as the result!\n  %749 = phi %CSo7UIColor* [ %703, %700 ], [ %731, %732 ], !dbg !517\nPHI node operands are not the same type as the result!\n  %1109 = phi %CSo7UIColor* [ %1125, %1124 ], [ %1102, %1104 ], !dbg !562\nPHI node operands are not the same type as the result!\n  %1125 = phi %CSo7UIColor* [ %1074, %1071 ], [ %1102, %1103 ], !dbg !562\nPHI node operands are not the same type as the result!\n  %1462 = phi %CSo7UIColor* [ %1478, %1477 ], [ %1455, %1457 ], !dbg !604\nPHI node operands are not the same type as the result!\n  %1478 = phi %CSo7UIColor* [ %1427, %1424 ], [ %1455, %1456 ], !dbg !604\nLLVM ERROR: Broken function found, compilation aborted!\n",
--- SNAP ---

I'm sure the Swift developers will be most interested in a bug report will all this info.

Cheers,

Project builds fine for earlier compiler releases. The crash gives no stack trace in console. The crash occurs for one framework component within a complex project with multiple frameworks + app with lots of inter-dependency so its hard to know what specifically is causing the issue or produce something to reproduce and file with a bug report. If I turn off optimisation for that one framework the whole project builds.
