[swift-users] [Swift Package Manager] Use of Info-plist; use for apps

[Zach Waldowski]

I haven’t yet had the pleasure of investigating what’s available in
3.2/4.0’s swiftpm, but I did once hack this together in the 3.x
toolchain using a dummy module:

Hierarchy:
Sources/
-- InfoPlist
---- Dummy.c
---- include/
------ InfoPlist.h

InfoPlist.h: 
```
__attribute__((used, section("__TEXT,__info_plist")))
static const char __darwin_info_plist[] = "<##escaped XML string##>";

__attribute__((used))
static inline void includeInfoPlist(void) {
    (void)(__darwin_info_plist);
}
```

partial main.swift:
```
import InfoPlist

includeInfoPlist()
```

I sure do hope there’s a better way to do this now, but just throwing it
out there for posterity.

Sincerely,
  Zachary Waldowski
