I am not a fan of Xcode.  Here are ~160~ 200 problems, the first hundred or so issues were filed mostly in 
July and August 2016 in a fit of rage.  Mostly on weekends working (slowly) on side-projects.  I have also
taken days of my employer's time filing others of these - so the company was not getting value for my time.

I believe a paid intern could have found many of these - just start a screen recorder, and when you see something,
stop and cut a quick movie.  Many have been around for several major versions.
I'm volunteering chunks of my life (15-30 minutes per) to one of the most valuable companies in the world, which seems
kind of messed up. Things get worse the more complex the project and the longer Xcode been's running.

@interface BNRDiggyDict : NSObject

// React to object indexing.  Would be nice to have a @protocol for this
- (id) objectForKeyedSubscript: (id) key;
- (void) setObject: (id) thing  forKeyedSubscript: (id<NSCopying>) key;

// And for fun, it also can react to scalar indexing.
// Returns the N'th key of the top-level collection.

Hi!  Thanks for looking

TL;DR - trying to do anything with os_signpost, but nothing is appearing in instruments.
UPDATE: on devices it's working.  Is it supposed to work in the simulator?  Points of Interest are on built-in templates, I figured it should work on the device...

The app is all objc, using the C API.  See at the end for a swift attempt

More details:

Creating the log like this:

// clang -g -Wall -fobjc-arc -framework Foundation -o serial serial.m


static id makePlistObjects (void) {
    NSMutableDictionary *top = [NSMutableDictionary dictionary];

    [top setObject: @"Hi I'm a string"  forKey: @"string"];
    [top setObject: [NSNumber numberWithInt: 23]  forKey: @"number"];
