    March 24, 2020

    πŸš€ This release has been the product of months of daily work. Most of FLEX was rewritten from the ground up. If you want to show your appreciation, I have a GitHub Sponsors profile with a range of tiers where you can donate to me on a monthly basis. I also have Cash App ($tannerbennett). Reach out to me on Twitter if you have any questions or concerns about anything!

    (This is by no means a complete list of changes)


    • ⬇️ Drops support for iOS 8 β€” if you need to support iOS 8, use FLEX 3
    • Tabs! Every screen now has a toolbar you can use to view the list of open tabs and switch between them.
      • Background a tab by swiping down to dismiss the view controller (yes, even if you're not on iOS 13, try it)
      • Close a tab by pressing the "Done" button or by deleting it from the tabs list
    • Bookmarks! Bookmark objects to save them for later
      • Hit the + button in the tabs list to open a tab from a bookmark
    • πŸ†• New icons for the FLEX toolbar, taken from SFSymbols (yay @3x)
    • 🌲 System log is back from the dead: iOS 10 largely broke the system log feature with the addition of os_log. FLEX now forces NSLog() to use ASL so you don't get a log full of useless internal junk
    • βž• Added various singletons to the main menu screen
    • Dark mode improvements
    • βš™ Run queries on SQLite databases (thanks @LesykMelnychuk)
    • Most screens are now searchable, including lists of object references and the keychain

    • πŸ†• New APIs for customizing "shortcuts" that are displayed for any given object or class
    • πŸ“‡ Uses a monospace font for displaying metadata

    • Protocol conformances are listed at the bottom, as well as instance size and image of origin
    • βž• Added various helpful shortcuts to a number of classes
    • Fine-tuned the shortcuts for various UIKit classes
    • Swipe left or right to change your position in the class hierarchy
    • Tapping on a property or ivar now takes you to the value; press the detail button to edit instead
    • βž• Added a section index control to aid in quickly jumping to a specific metadata section
    • βž• Added a toolbar with quick access to helpful toggles or options

    • Translucency is now correct
    • nil background colors don't show a color indicator at all

    πŸ’» Runtime Browser

    • Replaces the System Libraries and App Classes screens
    • Browse the runtime using a key-path-like syntax: bundle.class.method
      • Accepts wildcards, like *.*View* which will list all classes that contain View
      • Currently only supports searching for methods, properties and ivars soon to come
      • Search for an instance method with -methodName, a class method with +methodName, or either by prefixing your query with a wildcard
      • For example, UIKit*.*Controller.*foo searches for any method containing foo in any class ending with Controller in any loaded bundle starting with UIKit

    Method Calling

    • βž• Added a "paste" button to argument input accessory views, useful for pasting an address
    • βž• Added support for char * and SEL parameters

    • Easy access to the "clear" button in the toolbar

  • v3.1.0 Changes

    November 14, 2019

    Marking this as 3.1 instead of 3.0.1 because we don't really have much of an "API" to use for semantic versioning, but a lot changed under the hood so I think a minor version change is warranted.

    • πŸŽ‰ Initial support for iOS 13 and dark mode
    • πŸ‘ Allow passing addresses for id arguments
    • βž• Added a custom class hierarchy scope bar to the object/class explorer
