Have I mentioned lately how awesome NSScreencast is? No? Worth the subscription. Check it out if you’re an iOS developer. Or even if you’re not and you want an example of how to do coding screencasts well.

Got tired of dead-end googling so I checked to see if @NSScreencast had covered what I was looking for. Of course he had, 4 years ago. Should have checked there first.

One 13-minute episode of @NSScreencast just paid for the yearly subscription fee in amount of time saved. Do it.

Seriously great stuff even for seasoned developers. I’ve learned a good amount from Ben’s videos.

You can really expand your development horizons in just a few minutes a week with NSScreencast.

Random PSA for iOS developers: @NSScreencast is a great resource, and worth every penny. It’s high quality, practical, and honest.

Can’t say enough good things about @NSScreencast There is gold in the Road Trip DJ Series.

I just reuppped my subscription to @NSScreencast. [An] indespensible resource if you’re into iOS or Mac Development.

Just finished @NSScreencast series on Modern CollectionViews. Strongly recommended. Programmatic UI, nicely structured code, easily approachable explanation style. 👌

  • #348

    Unified Logging and Activity Tracing

    Signposts are a special part of the Unified Logging and Activity Tracing system. They allow you to mark point-in-time events that occur in your code, or track the duration of operations by specifying the begin and end for an activity. These can be visualized in Instruments to get a rich, high level view of how these operations are performing, how often they are occurring, and how long they are taking. In this episode we will see how to add signposts to an app and how to view these signposts in Instruments.

    Unified Logging and Activity Tracing

    Console.app is a nice way of viewing logs, but most of this power (and more) is builtin to the log utility from the command line. In this episode we will see how to stream debug logs from the simulator, as well as how to retrieve logs from customer or tester devices out in the field by triggering a sysdiagnose.

  • #345

    Unified Logging and Activity Tracing

    In this episode we talk about public versus private data (and how to change the defaults). We also look at using the log command line tool for a deeper understanding of the unified logging system and how we can tweak it for our needs.

  • #344

    Unified Logging and Activity Tracing

    In this episode we show how you adopt the Unified Logging framework in code by using the OSLog type to define your log subsystems and categories, and how to use os_log to actually log events and messages.

  • #343

    Unified Logging and Activity Tracing

    A high level overview of the new Unified Logging system, which covers the benefits of the new system, a high level overview of how it works, and some things to consider when adopting the new system.
