Cannot build Xcode target "breadwallet"

[taoeffect]

After over an hour of fighting with the project, installing JDK 11 (because the newer ones won't work with gradle due to java.lang.IllegalArgumentException: Unsupported class file major version 62), hacking the gradle files to let it run ./gradlew linkDebugFrameworkIosArm64 linkReleaseFrameworkIosArm64 because I don't have (and don't need) the Android SDK installed, I still get this same error, and have no clue how to get past it.
