How to display build log in Xcode

Xcode has a very minimalistic design when working with build errors. Sometimes it’s necessary to get more information about a failed build and it might not be obvious how to do it.

The answer is simple and it’s one click away.

Click on the last icon (text bubble) in the top left panel.

Now select the build and you’ll see all build information.

SDL2_image for iOS with JPEG image format

Adding SDL2_image with JPEG support for iOS is a little bit different than for Android. In case of Android, it was necessary to add JPEG library in C and build it. iOS has JPEG dependency hidden in another library which is already compiled in frameworks.

If you just add SDL2_image to your project for iOS, you will very likely end up with following linker error:

"_kUTTypeJPEG", referenced from ...
Linker command failed with exit code 1

To resolve this issue, it is sufficient to add two dependencies into your project.

Go to Project and select Build Phases.

In the section Linking add library: ImageIO.framework

Then add the second dependency: MobileCoreServices.framework

Then Clean and Build the project.

These steps should resolve the linker issue, and JPEG should work.
