When using the latest swiftlint 0.51.0, xcodeproj's prebuild script occurs a fatal error.
So, the build failed for users who use carthage and install the latest swiftlint.
And, xcodeproj file contains missing reference files. So I deleted it.
This PR contains the following:
[x] Fix swiftlint serious violations.
[x] Delete missing reference in xcodeproj
[x] Equal xcodeproj's ios minimum development target to Package.swift
