Debugging the Swift Toolchain

Use these steps to debug components of the Swift toolchain. This allows you to see Swift's source code from the debugger – instead of disassembly. The debugger can also provide some variable names and values. This has been initially tested with libswiftCore.dylib.

These instructions were updated as of Swift 5.2.1.

class PointerEnabledButton: UIButton {

        super.init(frame: frame)
        if #available(iOSApplicationExtension 13.4, *) {
            enablePointer()
        }
    }

import UIKit

/// A scroll view that allows scrolling using a hardware keyboard like `NSScrollView`.
/// Supports arrow keys, option + arrow keys, command + arrow keys, space bar, page up, page down, home and end.
/// Limitations:
/// - Paging scroll views (isPagingEnabled = true) are not supported yet.
/// - The scroll view must become its own delegate so setting the delegate is not supported yet.

libdispatch efficiency tips

The libdispatch is one of the most misused API due to the way it was presented to us when it was introduced and for many years after that, and due to the confusing documentation and API. This page is a compilation of important things to know if you're going to use this library. Many references are available at the end of this document pointing to comments from Apple's very own libdispatch maintainer (Pierre Habouzit).

My take-aways are:

• You should create very few, long-lived, well-defined queues. These queues should be seen as execution contexts in your program (gui, background work, ...) that benefit from executing in parallel. An important thing to note is that if these queues are all active at once, you will get as many threads running. In most apps, you probably do not need to create more than 3 or 4 queues.

• Go serial first, and as you find performance bottle necks, measure why, and if concurrency helps, apply with care, always validating under system pressure. Reuse
