iOS only runs app bundles, so with HEADLESS=ON the iOS build makes PPSSPPHeadless an app (org.ppsspp.headless) that starts UIKit and runs the headless main on a thread with the arguments devicectl launched it with. Vulkan only, and the IR interpreter since there's no JIT. frametests.py --ios installs it, copies over the dumps the device lacks, and compares each render with the host's Vulkan one like --adb does. Each devicectl call costs a second or two, so the new --screenshot-dir lets one launch render a batch of dumps. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

|
|
// UIKit, so this starts UIKit and runs the headless main on a thread of its own, with the

// xcrun devicectl device process launch --console --device <udid> org.ppsspp.headless <args>

|
|
// Relative paths are resolved against the app's Documents directory, which
|
|
// `devicectl device copy to/from --domain-type appDataContainer` reaches. See frametests.py --ios.
