We now use BitByteData directly in TestSWCompression, so we need to link test target against BitByteData properly, the same way we do it for SWCompression. Since we don't want to unnecessary duplicate equal target settings, it was decided to make them project-wide.
Changed xcode version used in CI; changed swift version .swift-version file; changed swift version in podspec; changed swift badge in readme; consistently use double-quotes for strings in podspec; upgrade project to Xcode 9.3 and new project format; use Xcode's "new build system".
Carthage released an update which fixes the problem with unintended stripping of debugging symbols, thus, we no longer need to modify project settings to workaround this problem.
SWCompression is now linked against appropriate platform-version of framework using linker flags and framework search path; added custom shell script phase to TestSWCompression target, which copies appropriate platform-version of framework into test bundle (its presence is necessary to make it run).
Organization name set to "Timofey Solomko"; reset some settings to its default values; remove separate test project and workspace by merging them into main project; move plist files inside xcode project; use project-wide settings as much as possible; set project version 50 (total amount of releases on github) and CFBundleShortVersion to 4.0.1; versions in xcode project are now managed by agvtool: project version is increased by 1 whenever there is a new release, CFBundleShortVersion will continue to be semantically versioned; remove some unused settings; remove header file and empty build phases.
Use recommended settings for TestSWCompression; move SWCompression above TestSWCompression in workspace; remove internal workspace from SWCompression; remove platform-specific schemes and targets from SWCompression; enable support for all Darwin platforms in one target/scheme; set deployment targets as minimal as possible; set correct rpath for TestSWCompression; remove unwanted files from TestSWCompression; reorder files in TestSWCompression; add correct test action to SWCompression scheme; remove code-signing.
