Active Build Action (ACTION)

A string identifying the build system action being performed.

Additional SDKs (ADDITIONAL_SDKS)

The locations of any sparse SDKs that should be layered on top of the one specified by Base SDK (SDKROOT). If more than one SDK is listed, the first one has highest precedence. Every SDK specified in this setting should be a "sparse" SDK, for example, not an SDK for an entire macOS release.

A result type (based on swiftz) that can represent either an error or success:

enum Result<X, T> {
  case Err(() -> X)
  case Ok(() -> T)
}

Now we need a way to chain multiple results together without lots of nesting of if statements -- or exceptions. To do so, we can define a new bind (result, next) operator (implementation borrowed from swiftz) that operates on Result types (a.k.a flatMap or >>=):

• If the result is Err, the result is immediately returned.

Issue

Users report issues with code signing their Objective-C based project with the newly-rolled out Mavericks image on Travis CI.

The error looks something like:

Code Sign error: No codesigning identities found: No codesigning identities (i.e. certificate and private key pairs) that match the provisioning profile specified in your build settings ("Chappy Dev Adhoc") were found. CodeSign error: code signing is required for product type 'Application' in SDK 'iOS 7.1'

Workaround

A couple of users have reported that setting the keychain in use to be the default will fix this issue. For example:

prendio2

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
    
    NSIndexPath *selectedRowIndexPath = [self.tableView indexPathForSelectedRow];
    if (selectedRowIndexPath) {
        [self.tableView deselectRowAtIndexPath:selectedRowIndexPath animated:YES];
        [[self transitionCoordinator] notifyWhenInteractionEndsUsingBlock:^(id<UIViewControllerTransitionCoordinatorContext> context) {
            if ([context isCancelled]) {
                [self.tableView selectRowAtIndexPath:selectedRowIndexPath animated:NO scrollPosition:UITableViewScrollPositionNone];
