Summary:

When breaking up an array literal definition into multiple lines with Xcode, code formatting automatically aligns items with the opening square bracket “@[“. This can create potentially waste a lot of space on the left side and especially with longer definitions cause extra line breaks (see http://cl.ly/0x3Q1S18230P). This could be avoided by instead just indenting the same way a new scope (content between “{“ abd “}”) would be indented.

Steps to Reproduce:

Paste the following code snippet into Xcode:

[NSLayoutConstraint activateConstraints:@[
    [NSLayoutConstraint constraintWithItem:stateLabel attribute:NSLayoutAttributeCenterX relatedBy:NSLayoutRelationEqual toItem:self.view attribute:NSLayoutAttributeCenterX multiplier:1.0 constant:0.0],
    [NSLayoutConstraint constraintWithItem:stateLabel attribute:NSLayoutAttributeCenterY relatedBy:NSLayoutRelationEqual toItem:self.view attribute:NSLayoutAttributeCenterY multiplier:0.5 constant:0.0],
    [NSLayoutConstraint constraintWithItem:passwordField attribute:NSLayoutAttributeCenterX relatedBy:NSLayoutRelationEqual toItem:self.view attribute:NSLayoutAttributeCenterX multiplier:1.0 constant:0.0],
]];

Expected Results:

It would be formatted like this.

[NSLayoutConstraint activateConstraints:@[
    [NSLayoutConstraint constraintWithItem:stateLabel attribute:NSLayoutAttributeCenterX relatedBy:NSLayoutRelationEqual toItem:self.view attribute:NSLayoutAttributeCenterX multiplier:1.0 constant:0.0],
    [NSLayoutConstraint constraintWithItem:stateLabel attribute:NSLayoutAttributeCenterY relatedBy:NSLayoutRelationEqual toItem:self.view attribute:NSLayoutAttributeCenterY multiplier:0.5 constant:0.0],
    [NSLayoutConstraint constraintWithItem:passwordField attribute:NSLayoutAttributeCenterX relatedBy:NSLayoutRelationEqual toItem:self.view attribute:NSLayoutAttributeCenterX multiplier:1.0 constant:0.0],
]];

Actual Results:

Instead it is formatter like this. 

[NSLayoutConstraint activateConstraints:@[
                                          [NSLayoutConstraint constraintWithItem:stateLabel attribute:NSLayoutAttributeCenterX relatedBy:NSLayoutRelationEqual toItem:self.view attribute:NSLayoutAttributeCenterX multiplier:1.0 constant:0.0],
                                          [NSLayoutConstraint constraintWithItem:stateLabel attribute:NSLayoutAttributeCenterY relatedBy:NSLayoutRelationEqual toItem:self.view attribute:NSLayoutAttributeCenterY multiplier:0.5 constant:0.0],
                                          [NSLayoutConstraint constraintWithItem:passwordField attribute:NSLayoutAttributeCenterX relatedBy:NSLayoutRelationEqual toItem:self.view attribute:NSLayoutAttributeCenterX multiplier:1.0 constant:0.0],
                                          ]];

Note: 

Same holds for dictionary literals.
