![]() Budenholzer coached the Bucks to their first title in a half-century in 2021 but posted a 4-4 record in playoff series his other four seasons, including this year's first-round exit. That pretty much explains why the Bucks opted to fire coach Mike Budenholzer after he led Milwaukee to the NBA’s best record in three of his five seasons on the job.

Perhaps I’m naïve, but that doesn’t seem to me to be anything like what the docs were telling me to do it does, though, work a treat. Let theSctring = SecCopyErrorMessageString(theResult2, theReserved) Let theResult1 = SecKeychainSetUserInteractionAllowed(true) Let theReserved: UnsafeMutableRawPointer? = nil My first lesson in digging this particularly long and twisty trench is best summarised in the playground code which works: And as I delve deeper, other docs tell me that I should not try to release a CFString at all. Then, we have to deal with SecCopyErrorMessageString(), which doesn’t return a Swift String at all, but CFString? The docs assure us that “You must call the CFRelease function to release this object when you are finished using it.” Only there isn’t a CFRelease function. Let theResult2 = SecKeychainUnlock(theChain, 0, theAccess, false) When the documentation refers to “passing NULL”, it actually means something more like Let theResult2 = SecKeychainUnlock(NULL, 0, NULL, false) Only that doesn’t mean that you would code the call as a Boolean value, which would be false as I am not passing a password.a buffer containing the password, or in my case “NULL if the user password is unknown” to display the Unlock Keychain dialog.As I was going to leave macOS to prompt for the password, this would be 0. an unsigned 32-bit integer giving the length of the password buffer.a reference to the keychain to unlock, for which I would “pass NULL to specify the default keychain.”.So I browsed the documentation using Dash, and discovered that SecKeychainUnlock() would have four parameters: SecCopyErrorMessageString() to convert any resulting error into a more informative text message.SecKeychainUnlock() to unlock the login keychain,.SecKeychainSetUserInteractionAllowed() to ensure that macOS displays its standard dialogs,.The sequence of calls is thus going to be: The first task which I set myself was producing code to lock and unlock the default user login keychain, using the standard system-supplied dialogs. That Apple recommends its open source security command tool (written mainly in C) as example code is very telling for someone working in Swift. My major problem, as seems always to be the case, has been the confusing documentation and lack of example code. On that I was wrong: everything that I have tried so far in a Swift playground has worked, once I have bludgeoned my way through the business of passing it the right parameters. ![]() I also feared that anything to do with keychains would be way off limits for Xcode’s Swift playgrounds. There have been several attempts to make Swiftian wrappers, but most are aimed primarily at iOS, none is comprehensive, and I decided, for better or worse, that I should develop my own solution. Despite that, the Swift interface to the many function calls to work with keychains are crude kludges from the Objective-C interfaces. This came as something of a shock, as Swift has been available for almost three years, has enjoyed very substantial resourcing within Apple, and is now at version 3.1. My first discovery was that the calls for working with keychains have not yet been made fully friendly to Swift. That was my intention, but reality went downhill from there. Browsing the features offered to apps, it seems possible to produce an app which can do much more, with less grief in terms of development. The snag with trying to use a scripting approach is that, while the security command offers a rich range of tools, there’s the ever-present problem of authentication. With the simple KeychainCheck as my starting point, I have launched into producing something better and more capable. From the number of people visiting this blog to read about the lack of tools for dealing with keychain problems, there is a need for better tools. ![]()
