Software source code previously released under an open source license and then modified by NGA staff is considered a "joint work" (see 17 USC § 101); it is partially copyrighted, partially public domain, and as a whole is protected by the copyrights of the non-government authors and must be released according to the terms of the original open source license.
Simple Features Projection is an iOS library for performing projection conversions between Simple Feature Geometries.

Be sure your Mac has the
glibtoolize utilities. These are required to build
the proj4-ios dependency. Without them,
pod install will fail. The easiest way to get these is to
brew install them:
brew install automake brew install libtool
Build this repository using Xcode and/or CocoaPods:
pod repo update pod install
Open sf-proj-ios.xcworkspace in Xcode or build from command line:
xcodebuild -workspace 'sf-proj-ios.xcworkspace' -scheme sf-proj-ios build
Run tests from Xcode or from command line:
xcodebuild test -workspace 'sf-proj-ios.xcworkspace' -scheme sf-proj-ios -destination 'platform=iOS Simulator,name=iPhone 14'
See the above note about
Include this repository by specifying it in a Podfile using a supported option.
