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.

Foster Bass

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.

Aijaz Ansari

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

Sam Soffes

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

James Dempsey

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

Alexis Gallagher

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

Nate Armstrong

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

Karl Oscar Weber

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

Marcus Ziadé

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

There are 7 episodes with tag 'logging'   Clear search
  • How to get logs from your app using OSLogStore

    #528

    In iOS 15 we can take advantage of the long-awaited OSLogStore, which allows you to capture and filter logs for your process on device. In this episode we will examine the NSScreencast application, which utilizes logging pretty extensively. We will build a rudimentary debug shake menu to show recent logs.

  • From os_log to Logger

    #527

    iOS 14 brought some nice improvements to os_log via a new type called Logger. This leverages Swift's StringInterpolation type to make it much more usable for formatting values inside your logs. It does this without sacrificing the privacy and performance that makes os_log so appealing. In this episode we will see how we can adopt this new API as well as how StringInterpolation works under the hood.

  • Using Signposts to Diagnose Performance Issues

    #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.

  • Streaming Logs with the log Tool

    #346

    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.

  • Private Data and the log Utility

    #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.

  • Using os_log to Log Messages

    #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.

  • Introduction to the Unified Logging Framework

    #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.
