Setting up IntelliJ IDEA as Diff and Merge Tool in Fork

To configure Fork to use IntelliJ IDEA for diffing and merging, follow the steps below.

1. Prerequisites

Ensure you have the command-line launcher idea installed.

• Path: /usr/local/bin/idea

/// Processes ARKits' ARFrame->capturedImage CVPixelBuffer according to the documentation into an sRGB image.
///
/// ARKit captures pixel buffers in a full-range planar YCbCr format (also known as YUV) format according to the ITU R. 601-4 standard.
/// (You can verify this by checking the kCVImageBufferYCbCrMatrixKey pixel buffer attachment.)
/// Unlike some uses of that standard, ARKit captures full-range color space values, not video-range values.

Current State of xcappdata

Apple feedback submitted: FB9905889

Up to Xcode version 13 xcappdata container are not behaving as expected: xcappdata container set in xctestplan configurations or via schemes ...

• ... will be transferred onto physical devices as expected ✅
• ... will NOT be transferred to the Simulator 🛑

Usage

1. swiftc main.swift -emit-module-path main.swiftmodule -emit-executable -enable-private-imports -Xfrontend -enable-implicit-dynamic
2. ./main -> prints From original bar()
3. swiftc -emit-library inject.swift -o inject.dylib -I . -Xlinker -undefined -Xlinker suppress -Xlinker -flat_namespace -Xfrontend -disable-access-control
4. DYLD_INSERT_LIBRARIES=inject.dylib ./main -> prints From replacement bar()

Notes

• Passing -Xfrontend -enable-implicit-dynamic removes you from having to add dynamic to everything you want to be replacable
