+  # This description is used to generate tags and improve search results.
+  #   * Think: What does it do? Why did you write it? What is the focus?
+  #   * Try to keep it short, snappy and to the point.
+  #   * Write the description between the DESC delimiters below.
+  #   * Finally, don't worry about the indent, CocoaPods strips it!

+  #
+  #  Licensing your code is important. See https://choosealicense.com for more info.

+  # ――― Source Code ―――――――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
+  #
+  #  CocoaPods is smart about how it includes source code. For source files
+  #  giving a folder will include any swift, h, m, mm, c & cpp files.
+  #  For header files it will include any header in the folder.

+
+  # ――― Resources ―――――――――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
+  #
+  #  A list of resources included with the Pod. These are copied into the
+  #  target bundle with a build phase script. Anything else will be cleaned.
+  #  You can preserve files from being cleaned, please don't preserve
+  #  non-essential files like tests, examples and documentation.
+  #
+
+  # spec.resource  = "icon.png"
+  # spec.resources = "Resources/*.png"

+
+
+  # ――― Project Linking ―――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
+  #
+  #  Link your library with frameworks, or libraries. Libraries do not include
+  #  the lib prefix of their name.
+  #
+
+  spec.framework  = "Poly"
+  # spec.frameworks = "SomeFramework", "AnotherFramework"

+
+  # ――― Project Settings ――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
+  #
+  #  If your library depends on compiler flags you can set them in the xcconfig hash
+  #  where they will only apply to your library. If you depend on other Podspecs
+  #  you can include multiple dependencies to ensure it works.
