There appear to be couple of things at play regarding rootless mode:/System/Library/LaunchDaemons/com.apple.rootless.init.plist - Calls /etc/libexec/rootless-init (registers with XPC?)/System/Library/Sandbox/rootless.conf - Configures the system locations to sandbox - an asteriks or name in the first column appears to override this globally or by executable name/System/Library/Sandbox/rootless.compat - Whitelisted executables? Legacy?/System/Library/Sandbox/com.apple.xpc.launchd.rootless.plist - XPC authorizations configThe one tool that can enable and disable rootless mode right now is on the Recovery partition under /System/Library/CoreServices/Security Configuration.app. It reboots the Mac immediately after applying the configuration change (it calls shutdown -r now).This appears to write a non-removable key (as far as I've been able to determine so far) named csr-active-config which the Security Configuration tool writes to. Notable is that this also appears to affect single user mode - I was not

Hi,if you're storing the tokens in a database (e.g. MySQL) you can set the SQL UNIQUE constraint for the column containing the tokens; this prevents a token from being stored twice. The UNIQUE constraint exists in MySQL, SQL Server, Oracle and MS Access databases. The following SQL statement creates a UNIQUE constraint on the 'Token' column when the DeviceInformation table already exists:ALTER TABLE DeviceInformation ADD UNIQUE (Token)All the best,Alex

No, the right column is blank when creating a new playground, too.I just updated to the 10.11 beta, and the issue is the same there.After sitting for about ten minutes, an error popped up:Error running playground.Failed to launch iOS stub for playground execution:error: no process found with ID 3436.I recall a similar error in 10.10.3.

I’m afraid there’s no magic bullet for this. PeterNeg is right that you have to use -tableView:heightOfRow:, but it’s quite complicated to set up, because you’ll need to maintain a cache or row heights (so that you don’t recalculate them every time your delegate is queried, which will slow things down), and you’ll have to do all the height calculations on your own using NSLayoutManager methods. You’ll also need to observe changes to the frame of the edited text field, and changes to the text, and tell your table to resize accordingly.Below is a full breakdown of how I achieve this in my app. Mine is done in NSOutlineView and in Objective-C, but the principle is the same, so you can adapt this for NSTableView and Swift.1. Keep a dictionary of row heights. This will store the row height NSNumber against a unique ID of some sort associated with your model object.2. Maintain an isRecalculatingRowHeights BOOL.3. Implement a -recalculateRowHeights method which:a. Removes all objects from the rowHeights dictionary.b

I slept on the problem and managed to find a workaround, although it's not a complete one.If I implement the delegate method -browser:numberOfRowsInColumn:, NSBrowser recognizes my object as an old-style delegate and will send all of the optional delegate methods. However, as I mentioned, this also severly limits the usability of NSBrowser because now calls to -itemAtRow:inColumn: and similar methods throw an exception that they are not supported.My solution (and by solution I mean hack) is to subclass NSBrowser and implement my own -itemAtRow:inColumn: method, like this:- (id)itemAtRow:(NSInteger)row inColumn:(NSInteger)column { NSMatrix* columnMatrix = [self matrixInColumn:column]; NSCell* cell = [columnMatrix cellAtRow:row column:0]; return cell.objectValue; }Since all of the cells in the NSMatrix are bound to the objects in the NSTreeController, the item of any given [row,column] is a well-known value. (Why NSBrowser can't do this is beyond me.)It doesn't solve the problem of -p

I agree with this sentiment.If I want to call a function/method as `moveBy(x: 3, y: 5)`, is there any reason why the syntaxfunc moveBy(x x: Int, y: Int)was preferred overfunc moveBy(x: Int, y: Int)and then just require an `_` otherwise?This seems counterintuitive to me as the goal of the parameters naming change was for consistency. Here's a comparison:Call siteSwift 1.xSwift 2.0Why not?moveBy(1, 1)func moveBy(x: Int, _ y: Int)func moveBy(x: Int, _ y: Int)func moveBy(_ x: Int, _ y: Int)moveByX(1, y: 1)func moveByX(x: Int, y: Int)func moveByX(x: Int, y: Int)func moveByX(_ x: Int, y: Int)moveBy(x: 1, y: 1)func moveBy(#x: Int, y: Int)func moveBy(x x: Int, y: Int)func moveBy(x: Int, y: Int)Compared to the current implementation, I find the last column to be readable and intuitive wether I know about swift's naming rules or not.

The general approach is outlined in the Cocoa Text Architecture Guide: Text System Organization – Common Configurations. Look for figure 3-5. You create the components of the text system separately, rather than just creating a text view and having it create the other components for you. You use a single text storage object, a single layout manager, and multiple text containers and text views. Each page-column is associated with a pair of text container and text view. You implement a delegate for the layout manager and implement -layoutManager:didCompleteLayoutForTextContainer:atEnd: to add additional columns and pages, along with their associated text containers and text views, as necessary to accommodate the text.

I just posted a reply with a sample project showing the issue, but of course, now that posts with links in them are moderated, that may not show up for a day or so. But essentially, it seems easy to reproduce this behaviour in a sample project as follows:1. Create a view-based NSTableView and hook it up to an NSArrayController (arrangedObjects and selectionIndexes bound to the array controller, the objectValue.key of the cell view text field bound to the cell view etc).2. Set the cell view's text field to be editable.3. In code, set the content of the array controller to an array of dictionaries simply containing e.g. @[@{key: @Foo}, @{@key: @Bar}] (but with a mutable array and dictionaries, of course).4. Set a -doubleAction on the table view (a dummy action will do).Once you've done all of the above, simply clicking on in the text area of a row causes it to be edited (after a slight delay) without needing to select it first and then click again. (2) and (4) are clearly the key culprits here. Back with cell-b
