Xcode files for building Previous on macOS.
Created with cmake -G Xcode, modified in Xcode 9 (9A235) to include /Library/Frameworks.
You'll need Xcode and SDL2.framework.
Run:
git clone https://github.com/itomato/Previous-Xcode
cd Previous-Xcode
xcodebuild -project Previous.xcodeproj
This should produce Previous.app in src/ and Previous.build/Debug/
open src/Previous.app
The same project and workspace files can be used in the Xcode GUI.
