/*:
 This is a concept re-implementation of the @Binding and @State property wrappers from SwiftUI

 The only purpose of this code is to implement those wrappers myself
   just to understand how they work internally and why they are needed,

 ⚠️ This is not supposed to be a reference implementation nor cover all
      subtleties of the real Binding and State types.
    The only purpose of this playground is to show how re-implementing
      them myself has helped me understand the whole thing better

New Build System Tricks

Command Line

# enable internal menu
defaults write com.apple.dt.Xcode ShowDVTDebugMenu -bool YES

alias xcbuild=$(xcode-select -p)/../SharedFrameworks/XCBuild.framework/Versions/A/Support/xcbuild

• Xcode build duration defaults write com.apple.dt.Xcode ShowBuildOperationDuration -bool YES
• Faster build times by leveraging multi-core CPU defaults write com.apple.dt.Xcode IDEBuildOperationMaxNumberOfConcurrentCompileTasks `sysctl -n hw.ncpu`
• Flag to emit warnings whenever a function takes longer than some threshold to compile. Add the following to Other Swift Flags
  • -Xfrontend -warn-long-function-bodies=100, where 100 is the number of milliseconds you’d like the warning threshold to be
• To enable warn about individual expressions that take a long time to type check, go the Build Settings, “Swift Compiler - Custom Flags”, “Other Swift Flags”, and add:
• -Xfrontend -warn-long-expression-type-checking= where `` is the lower limit of the number of milliseconds that an expression must take to type check in order for the warning to be emitted.

Build settings reference

Active Build Action (ACTION)

A string identifying the build system action being performed.

Additional SDKs (ADDITIONAL_SDKS)

The locations of any sparse SDKs that should be layered on top of the one specified by Base SDK (SDKROOT). If more than one SDK is listed, the first one has highest precedence. Every SDK specified in this setting should be a "sparse" SDK, for example, not an SDK for an entire macOS release.
