I downloaded files from a separate Stack OverFlow post, and dragged the folder into my project (as a group.) The dependancies get resolved and it shows no error for code that relies on the files, but when I try to compile I get this error: <unknown>:0: error: unexpected input file: /.../xyz.Swift Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swiftc failed with exit code 1 It might be nothing, but the files themselves in the project navigator show up as blank icons (while my project's other file have the swift red spalsh icon) despite checking in

I can't seem to get the text to actually span multiple lines. The heights look correct. What am I missing? - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:@"StatusCell"] autorelease]; CGRect frame = cell.contentView.bounds; UILabel *myLabel = [[UILabel alloc] initWithFrame:frame]; myLabel.text = [[person.updates objectAtIndex:indexPath.row] valueForKey:@"text"]; [cell.contentView addSubview:myLabel]; [myLabel release]; return cell; } - (CGFloat

The code is from Stanford CS193p. I added a NSLog to check it out. The label seems not being initialized. Any idea? @interface AskerViewController() <UITextFieldDelegate> @property (weak, nonatomic) IBOutlet UILabel *questionLabel; @property (weak, nonatomic) NSString *question; @end @implementation AskerViewController @synthesize questionLabel = _questionLabel; @synthesize question = _question; - (void)setQuestion:(NSString *)question { _question = question; self.questionLabel.text = question; NSLog(@"label is %@", self.questionLabel); } @end The NSLog result is: 2012-07-31 01:56:45.177

In case this illuminates the problem, here's the original Objective-C code. int x = (arc4random()%(int)(self.gameView.bounds.size.width*5)) - (int)self.gameView.bounds.size.width*2; int y = self.gameView.bounds.size.height; drop.center = CGPointMake(x, -y); I started out with this code. Lines 2 and 3 are fine, I'm presenting them for clarity later. let x = CGFloat(arc4random_uniform(UInt32(self.gameView.bounds.size.width * 5))) - self.gameView.bounds.size.width * 2 let y = self.gameView.bounds.size.height dropView.center = CGPointMake(x, -y) In Xcode 6 beta 3, it was necessary to cast the

I am trying to design a helper method which will retrieve a UIManagedDocument, then open and return it, so that I may access the same UIManagedDocument from several places in my app. I am having trouble with the asynchronous nature of this as I am not too familiar with blocks. Ideally the sequence of events would be this: Class X calls the helper method to retrieve the UIManagedDocument and includes a block of code to run when the opened document is returned. The class method retrieves the UIManagedDocument and calls openWithCompletionHandler or saveToURL as necessary, and includes a block of
