Goals
* Reflect Apple nullability annotations in our bindings using C#8
* No warnings when building bindings
Non-Goals
* Update (add or fix) `[NullAllowed]` to match Apple headers (next phase)
* Make the generator or internal code fully nullable aware (`nowarn` is used)
Notes
* Apple's own annotations are not 100% accurate :(
* Where known issue exists we have _fixed_ our attributes to match reality :)
* We also do additional null-checks internally that might seems not required (better safe than sorry).
- https://github.com/xamarin/xamarin-macios/issues/3367
- App Store will now fail builds if you add in a 32-bit dylib
- If you are a 32-bit app you don't need the 64-bit part of your fat
dylib anyway
- Add --optimize=-trim-architectures to allow customization of behavior, as not everyone
uses app store
In addition, while writing tests for this is was noticed that mmp tests did not "really" run Release configuration correctly in most cases. Fixing this turned out to be a bit of a pain, but necessary to correctly test this (and other things).
- Turns out that /p:configuration:debug is not sufficient to tell mmp to
do the right thing
- That, in most projects, sets the DebugSymbols property, which really
is what is checked.
- However, two of our projects did not have that, so we always did
release mmp work.
- Removed configuration property for tests and added real "Release"
configuration option
