A dump of the SwiftUI.framework binary for the iOS simulator (as of Xcode 12.0 beta 2) using the swift-reflection-dump tool.
# Call this inside the bin directory of a build of the Swift compiler,
# e.g. build/Xcode-ReleaseAssert/swift-macosx-x86_64/Release/bin.
# Adjust the path to match your Xode installation or pick a different binary to dump.
# Tested with Xcode 12.0 beta 2.
# Note: I used a Swift 5.3 compiler build from a few weeks ago that I had laying around.
# Because of ABI stability, I don't think the swift-reflection-dump version has to match
# the compiler version that was used to build the binary, but I'm not 100% sure.
