iOS: Xcode warnings

[hbugdoll]

Introduction

Motivated by https://github.com/tidev/titanium-cli/issues/593 I took a closer look at the log messages during the build process (app build and SDK build).

Currently, almost all Xcode warnings end up at log level trace – there are quite a lot of them.
 I have marked the warnings in the SDK build, because they are (a little bit) less relevant. A normal user is more likely to use a compiled/published SDK version.

The following list is intended as an overview and will be continuously updated.
