To be able to build SDL2 application on iOS with Xcode, follows the following steps.

For this tutorial, I use Mojave 10.14 (18A391) and XCode 10.0 (10A255).

Create an Xcode project

Create a simple view based application. It can be either swift, or objective-c project. In this case, I choose swift. Name your project, in this case we go with sdl-ios, and bundle identifier properly.

Setup Xcode project

  • Remove Main.storyboard, Viewcontroller.swift, AppDelegate.swift files from the project. Choose Move to Trash is ask, SDL2 handles these for us already.
  • Remove Main storyboard file base name item from Info.plist file. As we already removed storyboard file, we don't need it.
  • Add SDL Xcode project as a sub-project by right click on folder sdl-ios directory then choose "Add Files to "sdl-ios"" then select <your SDL source directory>/Xcode-iOS/SDL/SDL.xcodeproj.
  • Click on sdl-ios in project navigation panel, then click on Build Phases->Link Binary With Libraries->+ symbol then choose libSDL2.a from 'libSDL-iOS' target in 'SDL' project.
  • Further add GameController.framework, Foundation.framework, UIKit.framework, OpenGLES.frameworkd, QuartzCore.framework, CoreAudio.framework, AudioToolbox.framework, CoreGraphics.framework, CoreMotion.framework, Metal.framework, CoreBluetooth.framework, and AVFoundation.framework.
  • Create a new directory called src then put SDL2 source files inside e.g. you can use rectangles.c, common.c, and common.h file as seen in <your SDL source directory>/Xcode-iOS/Demos/src
  • Right click on sdl-ios in project navigation panel in Xcode then choose "Add Files to "sdl-ios"" to select src directory as we added eariler.
  • Click on Build Settings then search for "Header Search Paths", then add <your SDL source directory>/include.

Build SDL2 Library (optional)

Just for checking.

  • Click to change Xcode's project target to libSDL-iOS.
  • Build the project with Cmd+B.
  • You should see it successfully built.

Build SDL2 Application

  • Click to change Xcode's project target to sdl-ios (your target sample).
  • Run the project with Cmd+R.
  • You should see it successfully built and see the screenshot similar to below

What's Next

Now you can add more sample source files into src directory then create a new Xcode target duplicating from what we currently have for sdl-ios in order to run another sample.

As well, you can even include Icon.png and setup Default.png to launch screen as seen in <your SDL source directory>/Xcode-iOS/Demos to your Xcode project to let it has default icon and launch screen shown.
